Material from lectures 


disputatie
The picture is a page from "Het bloedig Tooneel, of Martelaars Spiegel" from 1685 (book 2, page 425), a book describing various kinds of tortures - as in this example: to have to have a dispute with Mr Broer Cornelis (sic). As a modern equivalent, I offer some of my lectures.
