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 (Orions 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 Orions first option.
Etymology
Eunuch comes from the Ancient Greek word εὐνοῦχος (eunoukhos), 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 eunoukhos. "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, to tēn eunēn ekhein, "guarding the bed", a derivation inferred from eunuchs established role at the time as "bedchamber attendants" in the imperial palace, and second, to eu tou nou ekhein, "being good with respect to the mind", which Orion explains based on their "being deprived of intercourse (esterēmenou tou misgesthai), the things that the ancients used to call irrational (anoēta, literally: mindless)". Orions second option reflects well-established idioms in Ancient Greek, as shown by entries for transl. grc – transl. noos, eunoos and ekhein in Liddell and Scotts Greek-English Lexicon, while the first option is not listed as an idiom under eunē 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 (eunē) and claimed that the very word eunuch attested to this kind of employment.
