Calendar of Philocalus (354 AD) places the Roman Lychnapsia ''
pridie Idus Augustas'', the day before the
Ides of August, a month when the Ides fell on the 13th. It began to be celebrated after the mid-1st century AD.
Mommsen conjectured that it was introduced around 36–39 AD along with the longer Roman Isiac festival held October 28 through November 3. During this period, the fourth epagomenal day would have coincided with August 12 on the Roman calendar. According to this theory, the Lychnapsia would have been a Roman celebration of the ''
dies natalis'' ("birthday") of Isis.
