Lucas Cranach the Elder, Saints Christina and Ottilia, 1506. National Gallery, London.

Saint Christina is shown standing on her attribute, the millstone, as according to her legend she was thrown into Lake Bolsena in Tuscany after converting to Christianity (a trial she miraculously survived). Saint Ottilia (aka St Odile of Alsace) is said to have miraculously recovered her sight after being baptised by Saint Erhard of Regensburg; her eyes are balanced on the book she is carrying.
