Science Art: Growth of Egg of Hen, c. 16th century.

Growth of Egg of Hen, from De formatione ovi, et pulli / [Fabricius ab Aquapendente]

From De formatione ovi, et pulli, by Fabricius ab Aquapendente, also known as Hieronymus Fabricius or Girolamo Fabrizio d’Acquapendente. He was an Italian surgeon who helped found modern embryology at around the same time the first English colonies in North America were still just an idea, and cutting-edge transportation technology consisted of figuring out a way to stick another sail or two on a ship.

I found these eggs hidden in the Wellcome Library.
