L’Art de Régner is a tragi-comedy by Gillet de La Tessonerie, first published in 1645. It is unusual in that structurally each of its five acts is a separate playlet. The sub-title, Le Sage Gouverneur, refers to the role of a royal tutor, probably meant to be the duc de Bassompierre, to whom the play is dedicated.
Gillet de La Tessonerie’s tragi-comedy is an unusual example in French seventeenth-century theatre of a ‘play within a play’. The play has not been reprinted since 1645 and is an important example of diversity in early French classical theatre.
