“There is some debate over how Dürer accurately captured the image of the hare: he may have sketched a hare in the wild and filled in the individual details from a dead animal, or captured one and held it alive in his studio while he worked on the painting. A reflection of the window frame in the hare’s eye is often cited as evidence for the theory that Dürer copied the hare from life in his workshop, but this cross-barred reflection is a technique that Dürer frequently used to add vitality to the eyes of his subjects.”
