It is Easter tomorrow. A great moment to reflect on the death and resurrection of Jesus, you might say. But we will not be doing that. Easter is a Christian festival, but it also has a long secular tradition. This is reflected in Easter fires, Easter processions, Easter eggs and, of course, the appearance of the Easter bunny: the non-religious personification of the Christian festival. Just as Santa Claus is for Christmas. As a non-believer, Escher was not particularly concerned with the tradition of the festival, but he did depict a hare and two rabbits in his work. Clearly not intended to be Easter bunnies, but we’ll show them anyway.
