Johannes Cesaris (fl. 1406 – 1417) was a French composer of the late Medieval era and early Renaissance. He was one of the composers of the transitional style between the two epochs, and was active at the Burgundian court in the early 15th century.
Little is known about his life, excepting the years he was active in Bourges. He was a cleric for the Duke of Berry in Bourges in 1406, and maître des enfants (choirmaster to the boys) at the cathedral there from 1407 to 1409. In 1417 he was probably the organist at Angers cathedral. A Pierre Cesaris, possibly a relative, was active in Bourges until 1443. There is a reference in a contemporary poem, Le champion des dames by Martin le Franc to Johannes Cesaris being a popular composer in Paris in the early part of the century (this is the same manuscript that contains the famous portraits of Guillaume Dufay and Gilles Binchois).
Of his works, one motet, two ballades, and five rondeaux survive, as well as a sixth rondeau which has a contested attribution (it may be by Passet). Stylistically, they span both the manneristic complexities of the ars subtilior, which was the predominant style in Avignon in the 1390s, and the relatively simple song style of the early 15th century as it was developing in the courts of France and Burgundy. His motet A virtutis ignitio/Ergo beata/Benedicta filia, for four voices with three simultaneously sung texts, is isorhythmic in all parts. One of the secular songs, the rondeaux A l'aventure va Gauvain, is in a style which suggests the later generation, and may have been written later than 1417; indeed many of his pieces are from manuscripts dated from early to mid-century.
