Altarpiece of Saint George
On June 3, 1365, Pere the Ceremonious created the militia of the Centenar de la Ploma, initially called the Centenar of the Glorious Sant Jordi. After the Church of Sant Jordi in Valencia was consecrated on May 27, 1401, the Centenary commissioned an altarpiece for this church, which was made sometime between 1400 and 1420.   Due to its dimensions and complexity, the work probably had several authors, mainly Marçal de Sax and Miquel Alcanyís, but also very likely Johan Utuvert and Gonçal Peris .
