The first mention art of baking cheesecake appears in the work of the Greek philosopher Aegimus from the 5th century CE. Apparently, the cake was eaten by the Olympians.
Cheesecakes were also known in ancient Rome as libium. It was a cheesecake associated with religious rituals. The Cato the Elder in the work “De Re Rustica” included a recipe for it:
Bray 2 pounds of cheese thoroughly in a mortar; when it is thoroughly macerated, add 1 pound of wheat flour, or, if you wish the cake to be more dainty, ½ pound of fine flour, and mix thoroughly with the cheese. Add 1 egg, and work the whole well. Pat out a loaf, place on leaves, and bake slowly on a warm hearth under a crock.
