A Seventeenth-Century Engraving
Patavii: Apud Paulum Frambottum, 1634. An early classification of deformities, this is the first illustrated edition of Fortunio Liceti's work, originally published in 1616. It includes many firsthand descriptions made by Liceti himself.
This wood engraving depicts two cases reported in 1572 of ischiopagus conjoined twins joined in the genito-urinary area. Liceti reports that the girls shared one abdomen and one set of reproductive organs.
