Mikä on ollut muinaisessa Roomassa vietetyn kevätpäivän tasauksen juhla? Juvenalis tms. On kuulemma ilmestynyt Roomalainen kalenteri, josta tieto voisi löytyä.

Arto Kivimäen Roomalaisesta kalenterista vastausta en löytänyt, mutta internetistä löytyi erinäisiä linkkejä Google-hakukoneella http://www.google.com .
Hakusanoilla roma ja "vernal equinox" (=kevätpäiväntasaus, engl.) löytyi esim. seuraava linkki: Ancient Roman gods and goddesses http://www.crystalinks.com/romegods.html, josta selviää mm. seuraavaa:

"Mars was the consort of Rhea Sylvia and father of Romulus and Remus, and therefore the father of the Roman people. He was the Roman god of war, the beginning and ending of battles.

Mars was the god of young men and their activities, primarily war. He was celebrated in March and October. His festival was called the Quinquartus. It was five days of celebration during the vernal equinox. Mars was the son of Juno and the father of the twins Romulus and Remus, the founders of Rome. The planet Mars was named after the god because its red color looked like blood. "
