Image of the vagina and uterus, with a fetus showing in the womb at right. Drawn in the form of the male reproductive organs. In the 16th century, it was thought that female reproductive organs looked similar to male ones, except they were internal rather than external. From Georg Bartisch, "Kunstbuch," 1575. Georg Bartisch (1535-1607) was a German physician, considered a highly skilled practitioner of ocular medicine and surgery. He is credited for producing the first Renaissance manuscript on ophthalmic disorders and eye surgery, which was called "Ophthalmodouleia Das ist Augendienstz". It was published in 1583, and discussed ocular diseases, surgical techniques and instruments, as well as an ophthalmic atlas of 92 woodcuts depicting diseases of the eye. Bartisch is also remembered for his work in lithotomy for removal of urinary calculi. This version of the 16th century diagram published in 1908.
