Science Art: Fig. 179. – Profile view of a human embryo of about three weeks, showing the cephalic visceral arches and clefts and their relations to the arterial arches, from Quain’s Elements of Anatomy, 1898

This is a human embryo, from the first volume of an 1898 textbook for college students. The book was actually first published in the 1840s, meaning it’s probably best if we don’t dwell on where the models for the engravings were obtained.

Beautiful though they may be.
