"Étienne Chevalier (c.1410 in Melun – 1474) was a major civil servant of the French kings Charles VII and Louis XI. He is also notable for commissioning two major works by Jean Fouquet - the Melun Diptych (which he gave to the Collégiale Notre-Dame de Melun) and the Hours of Étienne Chevalier (in which he is shown twice praying before the Virgin, to whom he is presented by his patron saint Stephen)." - (en.wikipedia.org 11.08.2021)
