What is "cassandre"

Cassandre, pseudonym of Adolphe Jean-Marie Mouron (24 January 1901 – 17 June 1968) was a Ukrainian- French painter, commercial poster artist, and typeface designer.

It takes the form of a tragédie en musique in a prologue and five acts. The libretto, by Charles-François-Joseph-Victor de La Grange-Chancel, is based on the Oresteia by Aeschylus.
