Note 806 — BOOK XIII. THE NATURAL HISTORY OF EXOTIC TREES, AND AN ACCOUNT OF UNGUENTS.
John Bostock translation
This seems to have been a general name, as Pliny says, meaning an eunuch; but it is evident that it was also used as a proper name, as in the case of the eunuch who slew Artaxerxes, Ochus, B.C. 338, by poison, and of another eunuch who belonged to Darius, but afterwards fell into the hands of Alexander, of whom he became an especial favourite. The name is sometimes written “Bagoüs,” and sometimes “Bagoas.”
