Christmas round-up
A Christmas spirit hovers over Art of the Middle Ages at Sam Fogg (15d Clifford Street, W1, until 12 January), visible particularly in the Three Kings bearing gifts in the tiny 14th-century French ivory diptych, and in the green-winged stained-glass angel probably from the glazier who worked at Sées Cathedral, Orne in Normandy, around 1270–80.
