PR15302 Discovery of Pulmonary Circulation: adopted by Professor Anita Simonds, Harveian Librarian
We have saved the most drastic transformation for last!
The Discovery of Pulmonary Circulation is a printed item, something of a composite, made up of four images in the upper half and two columns of text below.
The images are a portrait of Michael Servetus in the centre, surrounded by reproductions of printed book pages: text on either side and a title page above.
The reproduced book pages are from Servetus’s work Restitutio Christianismi in which he rejects certain Christian doctrines and incidentally describes pulmonary circulation, the first European to do so. This challenged galenic medicine, some 75 years before William Harvey’s De Motu Cordis. Ibn-al Nafis, a 13th century Muslim physician had, already described pulmonary circulation, but it is unclear whether Servetus would have been familiar the work. Servetus was ultimately burnt at the stake for his heretical work, and thanks to it being embedded in a theological work, his description of pulmonary circulation suppressed and forgotten.
The text in the print provides some information about Michael Servetus and his work, but is mainly a translation from Latin of his description of pulmonary circulation, from Restitutio Christianismi.
In the lower right hand side corner of the page there is what appears to be the signature of William Osler , a prominent Canadian physician and collector of antiquities and books, though we are unsure why it is there.
This document was severely damaged, curling on the edges, with many tears and losses, and with ingrained dirt.
Conservator Vicky’s first step was to ask permission to slightly trim the page: a rare occurrence in conservation, however the damage was so extensive on the blank areas of the page, that this was deemed appropriate for this object on this occasion. The paper was cleaned with the vulcanised rubber sponges and eraser crumbs mentioned above, tears and losses were repaired with Western handmade paper, while the back of the brittle page was reinforced with Japanese tissue.
