The altarpiece was executed between 1329 and 1333 for the chapel of Sant\u27Ansano of the Cathedral in Siena by Simone Martini and his brother-in-law Lippo Memmi, to whom are attibuited the two lateral figures: saint Ansano - patron of Siena - and saint Giulitta. On the gold background the figures of Angel Gabriel and the Virgin enhances Gothic line, without narrative details: just the central pot with lilies, symbolizing Mary\u27s purity, and the olive branch. The golden relief inscription starting from the Angel\u27s mouth contains beginning words of the Annunciation.https://digitalcommons.usf.edu/saskia/2564/thumbnail.jp
