Abstract: The sixteenth-century chambers of rhetoric of the Low Countries wished to train new orators in the vernacular. They were thus closely tied to the educational domain. This article sheds new light on the connections between these two environments – chambers of rhetoric and schools – through the phenomenon of the rebus-poem. While this poetic form has long been considered as typical of the rhetoricians’ culture of the Low Countries, it probably developed through the interplay between Dutch and French as it was also used by plurilingual teachers.
