pridie kalendas martias

Amburbium -- a 'moveable feast' which may or may not have actually been held on this day, but does seem to have happened near the end of February. A sacrificial procession was led around the boundaries of the city as a rite of purification.

116 A.D. -- supplicatio pro salute Traiani (day 3)

1631 -- birth of Henry Stubbe (Greek and Latin scholar and author of a work which is rather timely today, it seems).
