A small book, of which only two copies survived, at the British Library and Cambridge University. As first shown by J F Payne in 1896, this work is very similar to a manuscript (MS 564) in the Wellcome Library. This manuscript is a fifteenth century (c.1475) copy of an earlier text written in Middle English around 1392 by an anonymous London surgeon, who copied the work of earlier writers. When first published this text was attributed to the 16th century English physician, surgeon and anatomist Thomas Vicary, who may have once owned the manuscript. Traditionally it was believed that this work had been first published in 1548, though no copies are known to exist. The text was first printed in the English translation of Thomas Geminus's anatomy (1553). In the second, significantly expanded, edition, issued in 1586 the title of the work was changed to The Englishmans treasure, or treasor for Englishmen: with the true anatomye of mans body.  See Duncan P.
