Petit Palais in Avignon
At the northern end of the large open space which begins with the Palais du Papes in Avignon, there is the Petit Palais which was extensively modified by Guiliano della Rovere who became Pope Julius II (known as Il Papa Terribile) who gave the dispensation for Henry VIII to marry Katherine of Aragon, and founded the Swiss Guard, among his other claims to fame.
Here is the view from the door of the Little Palace:
There are some more photos in the Flickr set but I was taken by this painting of St Peter by Taddeo di Bartolo of Siena (d.1422), with the apostle in a yellow toga:
Giovanni Pagani of Monterubbiano in the Marches (d.1545) painted this unusual Vierge du Secours in which Our Lady illustrates the military maxim "Talk softly and carry a big stick."
I am back now from Avignon and back into the parish schedule. If you are waiting for a reply to an email that might take a few days...
