Antique print, titled: ''T.61.'' - Tab. 61: This detailed anatomical plate illustrates the structure and vascular complexity of the human placenta and umbilical cord membranes through a sequence of dissections and magnified views:The first figure shows the placenta (A) partially cleaned of adhering blood and glandular masses, with the chorion (B), amnion (C), and allantoic vessels (D) made visible. The fetal-facing side (E) shows intricate vascular networks, where the umbilical vessels (G) branch and interweave.The second figure demonstrates the separation of the outer chorionic membrane (A) from the amnion (B), laid flat with pins (C) and rolled onto paper (D) for clarity.In the third and fourth figures, the umbilical artery (III) and vein (IV) are dissected and inflated to reveal internal sinuses and folds, while the vessel walls are shown both in cross-section and in full length.The fifth figure focuses on a twisted section of umbilical cord (A), with arteries (B) and vein (C) injected with wax (red and brown), simulating blood flow and emphasizing the vessel layout.The sixth through eighth figures highlight the finest vascular branches, where capillary-like vessels spread to nourish placental villi, depicted with extreme delicacy some are broken or so fine they are nearly invisible to the naked eye.This visual exposition captures the intricate layering of membranes, the vascular architecture, and the capillary termination of fetal blood supply systems.

A later Dutch version of Govard Bidloo's most famous work, his monumental Anatomia humani corporis published in Amsterdam in 1685, containing 107 copperplate engravings. Like so many large and expensive anatomical atlases of the time, the work was not a financial success, and in 1690 he published a Dutch translation entitled, Ontleding des menschelyken lichaams, using the same plates. When this edition did not sell well either, Bidloo's publisher sold 300 of the extra printed plates to William Cowper, a noted English anatomist. Cowper published the plates with his own, English language text in Oxford in 1698 under the title, Anatomy of the humane bodies, without mentioning Bidloo or the artists of the original plates. Cowper went so far as to use Bidloo's engraved allegorical title page, amended with an irregular piece of paper lettered: "The anatomy of the humane bodies .," which fits over the Dutch title (see a comparison here). A number of vitriolic exchanges took place between Bidloo and Cowper, including several pamphlets published in each anatomist's defense. Cowper claimed, without much evidence presented, that the plates were not Bidloo's at all, but that they were commissioned by Jan Swammerdam (1637 1680) and that after his death Swammerdam's widow had sold them to Bidloo. The illustrations in Bidloos' work were drawn by Gerard de Lairesse (1640 1711) and engraved by Abraham Blooteling (1640 1690) and Peter van Gunst (1659? 1724?).Reference: Choulant, L.
