for her opinion: the panel was dated circa 1280 and considered to be from the same altarpiece as the Madonna and Child and the Flagellation. In 2006 her opinion was sought on a different artist, when two small paintings were discovered hanging in a modest terraced house in Oxford. They were identified as being by the 15th century Florentine artist Fra Angelico, and thought to be from a panel of eight saints, originally part of an altarpiece from the monastery of San Marco in Florence, dated circa 1440, commissioned by Cosimo de' Medici the Elder. The two paintings sold at auction for £1.7m in April 2007.
