This engraving is probably by Marco Dente, also known as Marco da Ravenna (1493-1527) after an original by his master, Marcantonio Raimondi, the first major Italian printmaker. It depicts a pagan sacrifice of a ram, being pulled towards an altar by a nude man. On the left is a priest with his head cloaked, and behind him a youth carrying a box. The print is styled on an ancient bas relief and is in the so-called King George IV album of Old Master prints, acquired by the Dominion Museum, forerunner of Te Papa, in 1910.
