The Vinalia were
Roman festivals in honour of
Jupiter and
Venus. The first was held on
August 19, and the second on
May 1. The Vinalia of
August 19 were called Vinalia Rustica, and were instituted on occasion of the war of the
Latins against
Mezentius; in the course of which war the people vowed a libation to Jupiter of all the wine in the succeeding vintage. On the same day likewise fell the dedication of a temple to Venus, whence some authors have fallen into a mistake that these Vinalia were sacred to Venus.
