BOUTS, bouts, Dirk or Dierick, wrongly styled Steurbout (c.1410-75). A Dutch painter, born at Haarlem. He was a pupil of Roger van der Weyden at Louvain, where, in 1466-68, he painted two pictures for the Church of Saint Peter, one of the “Martyrdom of Saint Erasmus” and one of the “Last Supper.” He also painted the “Martyrdom of Saint Hippolytus” and the “Torture of Saint Sebastian.” His brilliant coloring makes him one of the most significant members of the Flemish School, and his landscape backgrounds are especially good. His figures, on the other hand, are often disproportionately long and angular.
