A photograph sent to Christie’s request an auction estimate portal by an unsuspecting owner resulted in a $27.2 million (€23.02 million) sale in New York last week. The previously unknown red chalk study for a foot of the Libyan Sibyl in the Sistine Chapel made nearly 20 times its low estimate and set a record for a Michelangelo drawing. It measures just five and a quarter inches in height. A black chalk study for a leg with bent knee is on the back. Christie’s specialist Giada Damen identified it as an original drawing by Michelangelo, done in preparation for the right foot of the monumental figure at the far east end of the ceiling of the Sistine Chapel. The art brought multiple bidders in the room, on the phone and online to a 45 minute bidding battle at the sale of Old Master and British Drawings.
