Notes:
Guido da Vigevano (ca. 1280-ca.1349) was the personal physician to Joan of Burgundy, consort of Philip VI in the 1330s. Philip had twice pledged to lead a crusade to recover the Holy Land and, although he never did, Guido da Vigevano was so concerned how best to protect the king's life during the dangerous and unhealthy adventure of a crusade that he wrote a treatise called (in translation) Treasury of the King of France for the recovery of the Holy Land beyond the sea. The first part of this work is devoted to rules of health suitable for elderly warriors (Philip VI was then 42 years old) and the second half to siegecraft.
Guido da Vigevano's treatise on siegecraft includes a number of innovations, the most important of which was the idea of portability. Guido proposed constructing pre-fabricated sections of siege apparatus, each section small enough to be transported by horse, to compensate for the dearth of timber available in the Holy Lands. These pieces could be easily transported from to place to place and used many times. His treatise carefully described the towers and ladders, hinges, joints, bolts, ropes, and other small parts that allowed for the assembly of his designs; he comes close thus to the modern notion of interchangeable parts. In a similar vein, his treatise describes: a design for paddle wheels (to propel a portable boat) rotated by a double-compound crank; the use of wrought-iron for shafts and other structural purposes; a design for a sort of mechanical lift; a design for self-propelled battle wagon, employing a crank and a geared drive, with steerable fore-carriage; and a design for a tower windmill. However novel Guido's plans may have been, there is no evidence that any of them were ever built.
An analysis of the Texaurus is available in: Hall, A. Rupert. "Guido's Texaurus, 1335." On pre-modern technology and science. Ed. Bert S. Hall and Delno C. West. Malibu: Undena, 1976. Hall includes a translation into English of the manuscript version at the BNF (Latin 11015), together with notes on where that version differs from the present YCBA manuscript.
Accompanying the manuscript is another translation into English, in typescript, by an unidentified translator. It may have been prepared for the Sotheby's sale (1960), or shortly before. The introduction to this volume includes a history of the work and the provenance of the present manuscript. The volume is shelved with the present manuscript.
The manuscript is partially reproduced (26 of 52 pages, including all of the drawings), with commentary in: Le macchine del re : il Texaurus Regis Francie, di Guido da Vigevano; trascrizione, traduzione e commento del codice lat. 11015 della Bibliothèque nationale di Parigi di Giustina Ostuni. Vigevano : Diakronia, 1993.

On vellum.
Bound in later brown morocco.
Phillipps MS 16398.
Manuscript copy of Guido Vigevano's Texaurus Regis Francie, with 16 illustrations in pen and brown ink. The manuscript, written in Latin, includes only the second the part of the Texaurus, that dealing with siege warcraft. According to the colophon, the text was copied by Martin of Aachen in the kingdom of Cyprus in the year 1375. Martin in fact claims to be the compiler (copulatus) of the work, but this is an exaggeration, as the present manuscript is an almost exact copy of Guido's treatise, the earliest complete manuscript copy of which is present in the collections of the Bibliothèque Nationale de France (Ms Latin 11015, ca. 1340). The present version of the Texaurus was not copied from that in the BNF (see Hall).
The manuscript includes 16 full-page drawings in pen and brown ink, plus one smaller drawing of the author on p. [2], and a small number of interlinear diagrams, also in pen and brown ink. If the drawings are relatively rudimentary in technique, they do make an attempt to clearly articulate the mechanisms of the designs proposed by Guido.
