历史

太监一名始见于北魏，孝文帝置女官管理内事，其中有「大监」一职，在作司之下，女侍中之上，而古人常把「大」与「太」混用，故「大监」可能即为太监，如北齐时，宫女出身的穆黄花（字舍利）为北齐后主高纬临幸后被称为「舍利太监」。

唐代外朝官职中有大监，也作太监。

「太监」作为正式官名的记载始见于宋代，孙逢吉《职官分纪》载，宋太宗在内廷置内官（女官），有尚宫及太监，同负责内省事务，又改内省为尚书内省，尚书、太监并号尚书。这里的太监为高级女官职称，亦作大监。亦有其他官署设有太监官职。

辽代时，太监为南面官中太府监、少府监、秘书监、将作监、都水监等官署的主官，下有少监、监丞。

元代时，太监为艺文监、典用监、典医监、典牧监、甄用监、太府监、度支监、利用监、中尚监、章佩监、经正监、秘书监等官署皆设有太监官职，位次于各监的卿或太卿。

明代宫中设二十四衙门，内设十二监、四司、八局，各专设掌印太监一人提领。及其他机构主官，其中十二监中的内官监、御用监、四司、八局、内府供用库、提督东厂等，各设掌印太监一人。部分机构如司礼监除掌印太监外，还有提督太监、秉笔太监、随堂太监；提督京营除掌印太监外还有坐营太监。由于这些太监常由宦官出任，于是后来「太监」变成了高级宦官的称谓。但明代并无规定太监职位必须由宦官出任。

清朝时，宦官统称为太监，太监一词才完全与宦官同义。

1912年宣统退位后，便停止新招太监入宫，但直到1924年冯玉祥北京政变，驱逐逊清小朝廷后，所有太监才返乡，据称在第二次世界大战时的满洲国内部也存在一定数量的太监，但随著日本投降和苏联入侵满洲，太监从此彻底从中国官场中消失。

Etymology

Eunuch comes from the Ancient Greek word, first attested in a fragment of Hipponax, the 6th century BCE comic poet and prolific inventor of compound words. The acerbic poet describes a particular lover of fine food having "consumed his estate dining lavishly and at leisure every day on tuna and garlic-honey cheese paté like a Lampsacene "

The earliest surviving etymology of the word is from late antiquity. The 5th century (CE) Etymologicon by Orion of Thebes offers two alternative origins for the word eunuch: first, , "guarding the bed", a derivation inferred from eunuchs' established role at the time as "bedchamber attendants" in the imperial palace, and second, , "being good with respect to the mind", which Orion explains based on their "being deprived of intercourse, the things that the ancients used to call irrational (, literally: 'mindless')". Orion's second option reflects well-established idioms in Ancient Greek, as shown by entries for , and in Liddell and Scott's Greek-English Lexicon, while the first option is not listed as an idiom under in that standard reference work. However, the first option was cited by the late 9th century Byzantine emperor Leo VI in his New Constitution 98 banning the marriage of eunuchs, in which he noted eunuchs' reputation as trustworthy guardians of the marriage bed and claimed that the very word eunuch attested to this kind of employment. The emperor also goes further than Orion by attributing eunuchs' lack of male–female intercourse specifically to castration, which he said was performed with the intention "that they will no longer do the things that males do, or at least to extinguish whatever has to do with desire for the female sex". The 11th century Byzantine monk Nikon of the Black Mountain, opting instead for Orion's second alternative, stated that the word came from ( "good" + "mind"), thus meaning "to be well-minded, well-inclined, well-disposed or favorable", but unlike Orion he argued that this was due to the trust that certain jealous and suspicious foreign rulers placed in the loyalty of their eunuchized servants. Theophylact of Ohrid in a dialogue In Defence of Eunuchs also stated that the origin of the word was from eupnoeic and ekhein, "to have, hold", since they were always "well-disposed" toward the master who "held" or owned them. The 12th century Etymologicum Magnum (s.v. eunoukhos) essentially repeats the entry from Orion, but stands by the first option, while attributing the second option to what "some say". In the late 12th century, Eustathius of Thessalonica (Commentaries on Homer 1256.30, 1643.16) offered an original derivation of the word from eunis + okheuein, "deprived of mating".

In translations of the Bible into modern European languages, such as the Luther Bible or the King James Bible, the word eunuchs as found in the Latin Vulgate is usually rendered as an officer, official or chamberlain, consistent with the idea that the original meaning of eunuch was bed-keeper (Orion's first option). Modern religious scholars have been disinclined to assume that the courts of Israel and Judah included castrated men, even though the original translation of the Bible into Greek used the word eunoukhos.

The early 17th-century scholar and theologian Gerardus Vossius therefore explains that the word originally designated an office, and he affirms the view that it was derived from eunē and ekhein (i.e. "bed-keeper"). He says the word came to be applied to castrated men in general because such men were the usual holders of that office. Still, Vossius notes the alternative etymologies offered by Eustathius ("deprived of mating") and others ("having the mind in a good state"), calling these analyses "quite subtle". Then, after having previously declared that eunuch designated an office (i.e., not a personal characteristic), Vossius ultimately sums up his argument in a different way, saying that the word "originally signified continent men" to whom the care of women was entrusted, and later came to refer to castration because "among foreigners" that role was performed "by those with mutilated bodies".

Modern etymologists have followed Orion's first option. In an influential 1925 essay on the word eunuch and related terms, Ernst Maass suggested that Eustathius's derivation "can or must be laid to rest", and he affirmed the derivation from eunē and ekhein ("guardian of the bed"), without mentioning the other derivation from eunoos and ekhein ("having a well-disposed state of mind").

In Latin, the words eunuchus, spado (Greek: spadon), and castratus were used to denote eunuchs.

By region and epoch

Ancient Middle East

The four-thousand-year-old Egyptian Execration Texts threaten enemies in Nubia and Asia, specifically referencing "all males, all eunuchs, all women."

Castration was sometimes punitive; under Assyrian law, homosexual acts were punishable by castration.

Eunuchs were familiar figures in the Assyrian Empire (ca. 850 until 622 BCE) and in the court of the Egyptian Pharaohs (down to the Lagid dynasty known as Ptolemies, ending with Cleopatra VII, 30 BCE). Eunuchs sometimes were used as regents for underage heirs to the throne, as it seems to be the case for the Neo-Hittite state of Carchemish. Political eunuchism became a fully established institution among the Achamenide Persians. Eunuchs held powerful positions in the Achaemenide court. The eunuch Bagoas (not to be confused with Alexander's Bagoas) was the Vizier of Artaxerxes III and Artaxerxes IV, and was the primary power behind the throne during their reigns, until he was killed by Darius III.

Marmon (1995) writes "Mamluk biographies of the eunuchs often praise their appearance with adjectives such as jamil (beautiful), wasim (handsome), and ahsan (the best, most beautiful) or akmal (the most perfect)."

Ancient Greece, Rome and Byzantium

The practice was also well established in other Mediterranean areas among the Greeks and Romans, although a role as court functionary does not arise until Byzantine times. The Galli or Priests of Cybele were eunuchs.

In the late period of the Roman Empire, after the adoption of the oriental royal court model by the Emperors Diocletian (r. 284–305) and Constantine (r. 306–337), emperors were surrounded by eunuchs for such functions as bathing, haircutting, dressing, and bureaucratic functions, in effect acting as a shield between the emperor and his administrators from physical contact, thus enjoying great influence in the imperial court (see Eusebius and Eutropius). Julian (r. 361–363) released the eunuchs from their service because he felt they were overpaid, and he subsequently realized how much they had contributed to palace operations.

The Roman poet Martial rails against a woman who has sex with partially castrated eunuchs (those whose testicles were removed or rendered inactive only) in the bitter epigram (VI, 67): "Do you ask, Panychus, why your Caelia only consorts with eunuchs? Caelia wants the flowers of marriage – not the fruits." It is up for debate whether this passage is representative of any sort of widely practiced behavior, however.

At the Byzantine imperial court, there were a great number of eunuchs employed in domestic and administrative functions, actually organized as a separate hierarchy, following a parallel career of their own. Archieunuchs—each in charge of a group of eunuchs—were among the principal officers in Constantinople, under the emperors. Under Justinian in the 6th century, the eunuch Narses functioned as a successful general in a number of campaigns.

Advantages of eunuchs were that they prevented offices from becoming hereditary, allowing appointments to be made on merit; they were more dedicated to their jobs, not being distracted by family obligations; and they were ineligible for the throne, and for that reason thought by emperors to be safe. Those who had been deprived not only of their testicles but also their penises were known in Greek as carzimasia, and were highly prized.

By the last centuries of the Empire, the number of roles reserved for eunuchs had reduced, and their use may have been all but over.

Following the Byzantine tradition, eunuchs had important tasks at the court of the Norman Kingdom of Sicily during the middle 12th century. One of them, Philip of Mahdia, has been admiratus admiratorum, and another one, Ahmed es-Sikeli, was prime minister.

China

In China, castration included removal of the penis as well as the testicles (see emasculation). Both organs were cut off with a knife at the same time.

Eunuchs existed in China from about 4,000 years ago, were imperial servants by 3,000 years ago, and were common as civil servants by the time of the Qin dynasty. From those ancient times until the Sui dynasty, castration was both a traditional punishment (one of the Five Punishments) and a means of gaining employment in the imperial service. Certain eunuchs, such as the Ming dynasty official Zheng He, gained immense power that occasionally superseded that of even the Grand Secretaries. Self-castration was a common practice, although it was not always performed completely, which led to it being made illegal.

It is said that the justification for the employment of eunuchs as high-ranking civil servants was that, since they were incapable of having children, they would not be tempted to seize power and start a dynasty. In many cases, eunuchs were considered more reliable than the scholar-officials. As a symbolic assignment of heavenly authority to the palace system, a constellation of stars was designated as the Emperor's, and, to the west of it, four stars were identified as his "eunuchs."

The tension between eunuchs in the service of the emperor and virtuous Confucian officials is a familiar theme in Chinese history. In his History of Government, Samuel Finer points out that reality was not always that clear-cut. There were instances of very capable eunuchs who were valuable advisers to their emperor, and the resistance of the "virtuous" officials often stemmed from jealousy on their part. Ray Huang argues that in reality, eunuchs represented the personal will of the Emperor, while the officials represented the alternative political will of the bureaucracy. The clash between them would thus have been a clash of ideologies or political agenda.

The number of eunuchs in imperial employ fell to 470 by 1912, when the practice of using them ceased. The last imperial eunuch, Sun Yaoting, died in December 1996.

Korea

The eunuchs of Korea, called 내시, 内侍|naesi, were officials to the king and other royalty in traditional Korean society. The first recorded appearance of a Korean eunuch was in Goryeosa ("History of Goryeo"), a compilation about the Goryeo dynasty period. In 1392, with the founding of the Joseon dynasty, the naesi system was revised, and the department was renamed the "Department of Naesi".

The naesi system included two ranks, those of 상선, 尙膳|Sangseon|translation=Chief of Naesi, who held the official title of senior second rank, and 내관, 内官|Naegwan|translation=Common official naesi, both of which held rank as officers. A total of 140 naesi served the palace in the Joseon dynasty period. They also took the exam on Confucianism every month. The naesi system was repealed in 1894 following Gabo reform.

During the Yuan dynasty, eunuchs became a desirable commodity for tributes.

Eunuchs were the only males outside the royal family allowed to stay inside the palace overnight. Court records going back to 1392 indicate that the average lifespan of eunuchs was 70.0 ± 1.76 years, which was 14.4–19.1 years longer than the lifespan of non-castrated men of similar socioeconomic status.

Vietnam

The Vietnamese adopted the eunuch system and castration techniques from China. Records show that the Vietnamese performed castration in a painful procedure by removing the entire genitalia with both penis and testicles being cut off with a sharp knife or metal blade. The procedure was agonizing since the entire penis was cut off. The young man's thighs and abdomen would be tied and others would pin him down on a table. The genitals would be washed with pepper water and then cut off. A tube would be then inserted into the urethra to allow urination during healing. Many Vietnamese eunuchs were products of self castration to gain access to the palaces and power. In other cases they might be paid to become eunuchs. They served in many capacities, from supervising public works, to investigating crimes, to reading public proclamations.

Thailand

In Siam (modern Thailand) Indian Muslims from the Coromandel Coast served as eunuchs in the Thai palace and court. The Thai at times asked eunuchs from China to visit the court in Thailand and advise them on court ritual since they held them in high regard.

Burma

Sir Henry Yule saw many Muslims serving as eunuchs during the Konbaung dynasty period of Burma (modern Myanmar) while on a diplomatic mission.

Arabian Peninsula

For several centuries, Muslim Eunuchs were tasked with honored roles in Medina and Mecca. They are thought to have been instituted in their role there by Salah ad-Deen Ayubi, but perhaps earlier. Their tasks included caring for the Prophet Muhammad's tomb, maintaining borders between males and females where needed, and keeping order in the sacred spaces. They were highly respected in their time and remained there throughout the Ottoman Empire's control of the area and afterward. In the present day, it is reported that only a few remain.

Ottoman Empire

In the Ottoman Empire, eunuchs were typically slaves imported from outside their domains. A fair proportion of male slaves were imported as eunuchs.

The Ottoman court harem—within the Topkapı Palace (1465–1853) and later the Dolmabahçe Palace (1853–1909) in Istanbul—was under the administration of the eunuchs. These were of two categories: black eunuchs and white eunuchs. Black eunuchs were African slaves who served the concubines and officials in the Harem together with chamber maidens of low rank. The white eunuchs were European slaves from the Balkans or the Caucasus, either purchased in the slave markets or taken as boys from Christian families in the Balkans who were unable to pay the Jizya tax. They served the recruits at the Palace School and were from 1582 prohibited from entering the Harem. An important figure in the Ottoman court was the Chief Black Eunuch (Kızlar Ağası or Darüssaade Ağası). In control of both the Harem and a net of spies among the black eunuchs, the Chief Eunuch was involved in almost every palace intrigue and thereby could gain power over either the sultan or one of his viziers, ministers, or other court officials. One of the most powerful Chief Eunuchs was Beshir Agha in the 1730s, who played a crucial role in establishing the Ottoman version of Hanafi Islam throughout the Empire by founding libraries and schools.

Coptic involvement

In the 14th century, the Muslim Egyptian religious scholar Taj-al-Din Abu Nasr 'Abdal-Wahhab al-Subki discussed eunuchs in his book Kitab Mu'id al-Ni'am wa Mubid al-Niqam (كتاب معيد النعم ومبيد النقم), a title that has been translated as Book of the Guide to Divine Benefits and Averting of Divine Vengeance and also as Book of Tutor of Graces and Annihilator of Misfortunes. In a chapter dedicated to eunuchs, Al-Subki made "the clear implication that 'eunuchness' is itself an office," Shaun Marmon explained, adding that al-Subki had specified occupational subgroups for the tawashiya eunuchs: the zimam watched over women, and the muqaddam al-mamalik over adolescent boys.

Edmund Andrews of Northwestern University, in an 1898 article called "Oriental Eunuchs" in the American Journal of Medicine, refers to Coptic priests in "Abou Gerhè in Upper Egypt" castrating slave boys.

Coptic castration of slaves was discussed by Peter Charles Remondino, in his book History of Circumcision from the Earliest Times to the Present, published in 1900. He refers to the "Abou-Gerghè" monastery in a place he calls "Mount Ghebel-Eter". He adds details not mentioned by Andrews such as the insertion of bamboo into the victim. Bamboo was used with Chinese eunuchs. Andrews states his information is derived from an earlier work, Les Femmes, les eunuques, et les guerriers du Soudan, published by a French explorer, Count Raoul du Bisson, in 1868, though this detail does not appear in Du Bisson's book.

Remondino's claims were repeated in similar form by Henry G. Spooner in 1919, in the American Journal of Urology and Sexology. Spooner, an associate of William J. Robinson, referred to the monastery as "Abou Gerbe in Upper Egypt".

According to Remondino, Spooner, and several later sources, the Coptic priests sliced the penis and testicles off Nubian or Abyssinian slave boys around the age of eight. The boys were captured from Abyssinia and other areas in Sudan like Darfur and Kordofan, then brought into Sudan and Egypt. During the operation, the Coptic clergyman chained the boys to tables, then, after slicing off their sexual organs, stuck a piece of bamboo into the urethra and submerged them in neck-high sand under the sun. The survival rate was ten percent. Slave traders made especially large profits off eunuchs from this region.

However, neither "Abou Gerbe", as an actual monastery, nor "Mount Ghebel Eter", as an actual location, are known. Additionally, the cited references from Andrews, Remondino and Spooner appear circular, originating in tales told by a single French explorer. The later cited sources simply copy the earlier ones. Further, the 90% mortality rate seems economically improbable, given that it would require that markets paid at least 15 times the value of an uncastrated slave boy for a eunuch slave boy. A modern peer-reviewed source reports survival in Chinese court castrations of children at 33%, which is quite low, but nevertheless far higher than reported by Remondino. The same source reports later adult castrations as having a survival rate of 98%. Consequently, the accounts of castration by Coptic monks reported above, along with the 90% mortality figure, should be treated with considerable skepticism.

Fatimid Caliphate

In the Shi'i Fatimid Empire (909 CE - 1171 CE), eunuchs played major roles in the politics of the caliphate's court. These eunuchs were normally purchased from slave auctions and typically came from a variety of Arab and non-Arab minority ethnic groups. In some cases, they were purchased from various noble families in the empire, which would then connect those families to the caliph. Generally, though, foreign slaves were preferred, described as the "ideal servants".

Once enslaved, eunuchs were often placed into positions of significant power in one of four areas: the service of the male members of the court; the service of the harem, or female members of the court; administrative and clerical positions; and military service. For example, during the Fatimid occupation of Cairo, Egyptian eunuchs controlled military garrisons (shurta) and marketplaces (hisba), two positions beneath only the city magistrate in power. However, the most influential Fatimid eunuchs were the ones in direct service to the caliph and the royal household as chamberlains, treasurers, governors, and attendants. Their direct proximity to the caliph and his household afforded them a great amount of political sway. One eunuch, Court Eunuch al-Jawdhar, became hujja to the Imam-Caliph al-Qa'im, a sacred role in Shia Islam entrusted with the imam's choice of successor upon his death.

There were several other eunuchs of high regard in Fatimid history, mainly being Abu'l-Fadi Rifq al-Khadim and Abu'l-Futuh Barjawan al-Ustadh. Rifq was a black African eunuch general served as governor of the Damascus until he led an army of 30,000 men in a campaign to expand Fatimid control northeast to the city of Aleppo, Syria. He was noted for being able to unite a diverse group of black Africans, Arabs, Bedouins, Berbers, and Turks into one coherent fight force which was able to successfully combat the Mirdasids, Bedouins, and Byzantines.

Barjawan was a European eunuch during late Fatimid rule who gained power through his military and political savvy which brought peace between them and the Byzantine empire. Moreover, he squashed revolts in the Libya and the Levant. Given his reputation and power in the court and military he took the reigns of the caliphate from his then student al-Hakim bi-Amr Allah; then ruled as the de facto Regent 997 CE. His usurpation of power from the caliph resulted in his assassination in 1000 CE on the orders of al-Hakim.

Since imams during this period ruled over a majority non-Shi'a population, the court eunuchs served an important informal role as ambassadors of the caliph, promoting loyalty and devotion to the Shi'a sect and the imam-caliph himself. The multicultural, multilingual eunuchs were able to connect to the commoners through shared cultural ground

Algiers

In the 16th century, an Englishman, Samson Rowlie, was captured and castrated to serve the Ottoman governor in Algiers.

Indian subcontinent (Central Asian Muslim conquerors)

Eunuchs in Indian sultanates (before the Mughals)

Eunuchs were frequently employed in imperial palaces by Muslim rulers as servants for female royalty, as guards of the royal harem, and as sexual mates for the nobles. Some of them attained high-status positions in society. An early example of such a high-ranking eunuch was Malik Kafur. Eunuchs in imperial palaces were organized in a hierarchy, often with a senior or Chief Eunuch (Urdu: Khwaja Saras), directing junior eunuchs below him. Eunuchs were highly valued for their strength and trustworthiness, allowing them to live amongst women with fewer worries. This enabled eunuchs to serve as messengers, watchmen, attendants and guards for palaces. Often, eunuchs also doubled as part of the King's court of advisers.

The hijra of South Asia

Hijra, a Hindi term traditionally translated into English as "eunuch", actually refers to what modern Westerners would call transgender women and effeminate homosexual men (although some of them reportedly identify as belonging to a third sex). The history of this third sex is mentioned in the Ancient Indian Kama Sutra, which refers to people of a "third sex" (triteeyaprakrti). Some of them undergo ritual castration, but the majority do not.

They usually dress in saris (traditional garb worn by women in India) or shalwar kameez (traditional garb worn by women in South Asia) and wear heavy make-up. They typically live on the margins of society and face discrimination. Hijra tend to have few options for earning a wage, with many turning to sex work and others performing ritualistic songs and dances. They are integral to several Hindu ceremonies, such as dance programs at marriage ceremonies. They may also earn a living by going uninvited to large ceremonies such as weddings, births, new shop openings and other major family events, and singing until they are paid or given gifts to go away. The ceremony is supposed to bring good luck and fertility, while the curse of an unappeased hijra is feared by many. Hijra often engage in prostitution and begging to earn money, with begging typically accompanied by singing and dancing. Some Indian provincial officials have used the assistance of hijras to collect taxes in the same fashion—they knock on the doors of shopkeepers, while dancing and singing, embarrassing them into paying. Recently, hijras have started to found organizations to improve their social condition and fight discrimination, such as the Shemale Foundation Pakistan.

Religious castration

Castration as part of religious practice, and eunuchs occupying religious roles, have been established prior to classical antiquity. Archaeological finds at Çatalhöyük in Anatolia indicate worship of a 'Magna Mater' figure, a forerunner of the goddess Cybele found in later Anatolia and other parts of the near East. Later Roman followers of Cybele were called Galli, who practiced ritual self-castration, known as sanguinaria. Eunuch priests also figured prominently in the Atargatis cult in Syria during the first centuries AD.

The practice of religious castration continued into the Christian era, with members of the early church practicing celibacy (including castration) for religious purposes, although the extent and even the existence of this practice among Christians is subject to debate. The early theologian Origen found evidence of the practice in : "His disciples said to him, 'If such is the case of a man with his wife, it is better not to marry.' But he said to them, 'Not everyone can accept this teaching, but only those to whom it is given. For there are eunuchs who have been so from birth, and there are eunuchs who have been made eunuchs by others, and there are eunuchs who have made themselves eunuchs for the sake of the kingdom of heaven. Let anyone accept this who can. (NRSV)

Tertullian, a 2nd-century Church Father, described Jesus himself and Paul of Tarsus as spadones, which is translated as "eunuchs" in some contexts. Quoting from the cited book: "Tertullian takes 'spado' to mean virgin". The meaning of spado in late antiquity can be interpreted as a metaphor for celibacy. Tertullian even goes so far with the metaphor as to say St. Paul had been "castrated".

Eunuch priests have served various goddesses from India for many centuries. Similar phenomena are exemplified by some modern Indian communities of the hijra, which are associated with a deity and with certain rituals and festivals – notably the devotees of Yellammadevi, or jogappas, who are not castrated, and the Ali of southern India, of whom at least some are.

The 18th-century Russian Skoptzy (скопцы) sect was an example of a castration cult, where its members regarded castration as a way of renouncing the sins of the flesh. Several members of the 20th-century Heaven's Gate cult were found to have been castrated, apparently voluntarily and for the same reasons.

In the Bible

The reference to "eunuchs" in Matthew 19:12 has yielded various interpretations.

Eunuchs are mentioned many times in the Bible, such as in the Book of Isaiah (56:4) using the word סריס (saris). Although the Ancient Hebrews did not practice castration, eunuchs were common in other cultures featured in the Bible, such as ancient Egypt, Babylonia, the Persian Empire, and ancient Rome. In the Book of Esther, servants of the harem of Ahasuerus, such as Hegai and Shashgaz, as well as other servants such as Hatach, Harbonah, Bigthan, and Teresh, are referred to as sarisim. Being exposed to the consorts of the king, they would likely have been castrated.

There is some confusion regarding eunuchs in Old Testament passages, since the Hebrew word for eunuch, saris (סריס), could also refer to other servants and officials who had not been castrated but served in similar capacities.

One of the earliest converts to Christianity was an Ethiopian eunuch who was a high court official of Candace, the Queen of Ethiopia, but was already a eunuch at the time of conversion (Acts 8:27–39).

Non-castrated eunuchs

The term eunuch has sometimes figuratively been used for a wide range of men who were seen to be physically unable to procreate. Hippocrates describes the Scythians as being afflicted with high rates of erectile dysfunction and thus "the most eunuchoid of all nations" (Airs Waters Places 22). In the Charlton T. Lewis, Charles Short, A Latin Dictionary, the term literally used for impotent males is spado but may also be used for eunuchs.

Some men have falsified the status of their castration to gain entrance into the palace. Chinese eunuch Lao Ai for instance, became the lover of the mother of Qin Shi Huang, who bore him two sons, before Lao Ai and his sons were executed after participating in a rebellion against Qin Shi Huang.

Castrato singers

Eunuchs castrated before puberty were also valued and trained in several cultures for their exceptional voices, which retained a childlike and other-worldly flexibility and treble pitch (a high-pitched voice). Such eunuchs were known as castrati.

As women were sometimes forbidden to sing in Church, their place was taken by castrati. Castrati became very popular in 18th century opera seria. The practice, known as castratism, remained popular until the 18th century and was known into the 19th century. The last famous Italian castrato, Giovanni Velluti, died in 1861. The sole existing sound recording of a castrato singer documents the voice of Alessandro Moreschi, the last eunuch in the Sistine Chapel choir, who died in 1922.

This Italian practice of castrating young males to maintain their soprano voices was ended by Pope Leo XIII (1878).

In popular culture

Notable eunuchs

In chronological order.

First millennium BCE

• Mutakkil-Marduk (8th century BCE): Assyrian chief eunuch, eponym of the year 798 BCE in an Assyrian eponym chronicle.

• Yariri (8th century BCE): regent of Neo-Hittite Carchemish thought likely to be a eunuch.

• Sin-shumu-lishir (7th century BCE): Assyrian eunuch who attempted to usurp power in the Neo-Assyrian Empire.

• Bagoas (4th century BCE): prime minister of king Artaxerxes III of Persia, and his assassin (Bagoas is an old Persian word meaning eunuch).

• Bagoas (4th century BCE): a favorite of Alexander the Great. Influential in changing Alexander's attitude toward Persians and therefore in the king's policy decision to try to integrate the conquered peoples fully into his Empire as loyal subjects. He thereby paved the way for the relative success of Alexander's Seleucid successors and greatly enhanced the diffusion of Greek culture to the East.

• Unidentified "Ethiopian eunuch" (1st century AD), from the Kingdom of Kush in modern-day Sudan, described in the Acts of the Apostles (chapter 8). Philip the Evangelist, one of the original seven deacons, is directed by the Holy Spirit to catch up to the eunuch's chariot and hears him reading from the Book of Isaiah (chapter 53). Philip explained that the section prophesies Jesus' crucifixion, which Philip described to the eunuch. The eunuch was baptized shortly thereafter.

• Halotus ( 20–30 CE – 70–80 CE), servant to the Roman Emperor Claudius and suspected of poisoning him.

• Cai Lun (–121): Former attribution to Lun as the inventor of paper has been rescinded following discovery of many earlier manuscripts written on paper. It is now highly questionable if he was directly involved in making paper.

• Zhang Rang: head of the infamous "10 Changshi" (ten attendants) of the Eastern Han dynasty.
