St Antony the Abbot is a 1530-1534 oil on canvas painting of Antony the Great by Moretto da Brescia on display on one of the side-altars in the Santuario della Madonna della Neve in Auro, Casto, Province of Brescia, Italy.
The first possible reference to the work is by Francesco Paglia in 1675 - in writing of Casto he states generally that in "Val Sabria beyond these are seen in some little churches works by Romanino and Moretto". It is impossible definitively to link this reference to specific paintings, but the only one still in this area is Moretto's St Antony the Abbot. Its commissioner is unknown, but was probably the town of Casto - the Santuario was built from 1527 onwards after a vision of the Virgin Mary and the canvas dates to the years immediately after this. There is no mention in later sources of the work being moved and so it seems to be on its original site.
