   In ancient Greece, the eponymous archon gave his name to the year in which he held office; he was accordingly known as an eponym.

   • 1615, Edward Grimeston, The Estates, Empires, & Principalities of the World, translation of original in French, page 975; translation of Pierre d'Avity, Les Estats, Empires et Principautez du Monde, 1613, page 1170:

     Before the Senat aſſembled to ſpeake, he that would propound any laws ſhould digeſt them in writing, in the office of Eponimes, to the end that according to the number, the people may haue a time preſcribed from the Nomothetes to examine them. And whoſoeuer requires the introduction of a new law, ſhall not only prefer it once, but euery day in the office of the Eponimes, vntil the Senat makes their solemne ſeſſion and aſſemblie. Let the Eponime chuſe out all the number of the Athenians, fiue men that may haue the charge to defend and protect the lawes.

     [original: Auant que le Senat s’aſſemble pour donner les voix, celuy qui voudra propoſer quelque loy, l’eſcrira au lieu des Eponimes, afin que selon leur nõbre le peuple peuſt auoir des Nomothetes le tẽps de les pouuoir premierement examiner. Et quiconque demandera qu’vne nouuelle loy ſoit introduite, la mettra non ſeulement vne fois, mais tous les iours au lieu des Eponimes, iuſques à ce que le Senat s’aſſemble. Que l’Eponime eſliſe de tout le nombre des Atheniens cinq hommes, qui auront la charge de deffendre les loix.]

     Note: D’Avity’s passage is a rough translation of Demosthenes’ Against Timocrates, 23. The Greek original says that the proposed laws were to be displayed “before the [monument of the] eponymous [heroes]” (πρόσθεν τῶν ἐπωνύμων) and that the people would decide how much time to give the nomothetes; it then says that the proposer should display the new law there every day until the assembly (ἐκκλησία) meets, and that five Athenians should be selected to speak in defense of laws being challenged before the nomothetes.

   • 1831, B. G. Niebuhr, translated by Julius Charles Hare, The History of Rome, page 415:

     An Athenian of the Æantid phyle did not believe himself to be descended from Ajax; or a Formian from Æmilus: these were only eponyms, honoured by the tribesmen as their common guardian spirits.

   • 1842, The History of Rome, page 715:

     Volesus, the eponym of the Valerii, […]

   • 1888, Evelyn Abbott, A History of Greece, pages 74, 83–84:

     (page 74) He was followed by Phlegyas, the eponym of the warlike Phlegyae, and Minyas, the son of Chryses, from whom the Minyae derived their name and their wealth.
     (pages 83–84) The kings who immediately follow Cecrops are mere inventions. Erysichthon and Erichthonius are repetitions of Erechtheus; Cranaus is an eponym [whose name is] derived from the old title of the Athenians, who were originally called Cranai, and Amphictyon is obviously a fictitious name.

     Note: In the second occurrence, eponym refers to a personage constructed so as to appear to be the name-giver of a people, although his name was actually derived from the said people's name.

4. Something that is named after a person.

   • 2015, Robert B. Taylor, What Every Medical Writer Needs to Know, →ISBN:

   • 2023 June 19, Rachel E. Gross, “Should Medicine Still Bother With Eponyms?”, in The New York Times‎^[1], →ISSN:

     An eponym was once considered medicine’s highest honor. Like monuments to great generals, they paid tribute to medicine’s most brilliant minds, ensuring their names would live on in perpetuity.
