Villard de Honnecourt (Wilars dehonecort, Vilars de Honecourt) was a 13th-century artist from Picardy in northern France. He is known to history only through a surviving portfolio or "sketchbook" containing about 250 drawings and designs of a wide variety of subjects.
Nothing is known of Villard apart from what can be gleaned from his surviving "sketchbook." Based on the large number of architectural designs in the portfolio, it was traditionally thought that Villard was a successful, professional, itinerant architect and engineer. This view is largely rejected today, as there is no evidence of him ever working as an architect or in any other identifiable profession, and the drawings contain many inaccuracies and misunderstandings that would be surprising from a practicing architect. He was possibly trained as a metalworker. Nonetheless, it is clear from his drawings that he was interested in architecture and that he traveled to some of the major ecclesiastical building sites of his day to record details of these buildings. His drawing of one of the west facade towers of Laon Cathedral and those of radiating chapels and a main vessel bay, interior and exterior, of Rheims Cathedral are of particular interest.
Villard tells us, with pride, that he had been in many lands (Jai este en m[u]lt de tieres) and that he made a trip to Hungary where he remained many days (maint ior), but he does not say why he went there or who sent him. It has recently been proposed that he may have been a lay agent or representative of the cathedral chapter of Cambrai Cathedral to obtain a relic of St. Elizabeth of Hungary who had made a donation to the cathedral chapter and to whom the chapter dedicated one of the radiating chapels in their new chevet. He also claimed to have made many of his drawings "from life" (al vif), an activity more usually associated with much later artists of the Renaissance.
The so-called "sketchbook" of Villard de Honnecourt (more correctly, an album or portfolio) dates to about c.1225-1235. It was discovered in the mid-19th century and is presently housed in the Bibliothèque nationale de France (BnF), Paris, under the shelfmark MS Fr 19093. It consists of 33 parchment sheets measuring on average 235x155 mm, or 9.25 x 6.1 inches. The manuscript is not complete, and its original extent cannot be determined. Because the drawings and captions are oriented in many different directions, the album appears to have been assembled in an ad hoc fashion, as if the individual sheets were not originally intended to be bound together into book form. It is unclear whether it was Villard himself or a later party who assembled and bound the leaves into a book.
