Sometime between 1502 and 1509 one of Antwerp's city clerks took time to pen a small drawing and inscription on the flyleaf of a document in his care (fig. 1). His depiction of a naked soul seen from the backside while ascending into the clouds of heaven, succinctly labeled “ascensio,” turns out to be only the first of several dozen doodles preserved in a special class of judicial manuscripts in the Antwerp city archives. Taken as a group, these pictorial and verbal jottings provide a unique opportunity to eavesdrop upon the spontaneous mental meanderings of several Antwerpians in the age of Metsys, Erasmus, Bruegel, and Plantin. The art of doodling is revealing by its very nature, and the possibility that one of the doodlers was the humanist Pieter Gillis provides an additional incentive for the discussion of this material, which is catalogued and translated in the accompanying appendix.
