- ludi Florales … a.k.a. Floralia (day 1) — a festival originally ordered in response to an interpretation of the Sybilline books in 238 B.C., it fell into desuetude only to be revived in 173 B.C.; it was a general festival of drinking and other merriment in honour of Flora, who presided over (of course) flowers and their blossoms (Chloris is also mentioned … I’m still trying to figure that one out).
- 4977 B.C. — birth of the universe, according to the calculations of Johannes Kepler
- 1737 — Birth of Edward Gibbon (he wrote some sort of book apparently)
