Ăgōnālĭa, ĭum or ōrum (like Saturnalia, Parentalia, etc.), n.,
I. a festival in honor of Janus, celebrated in Rome on the 9th of Jan. (V. Id. Jan.) and 21st of May (XII. Kal. Jun.).—Different derivations of the word were given by the ancients, concerning which see Ov. F. 1, 319-332. Ovid, in l. c., derives it from agonia, q. v. For other etym., v. the foll. art., and under agonium.

Origins

An unknown root + -ālia. One theory states that, while the festival was later performed in the Regia along the Via Sacra, the Regia used to reside on the Collis Quirinalis, which was formerly known as Agōnus and which gave the epithet Agōnensis to the Porta Collina.
