Gerard Horenbout (c. 1465 – 1541) was a Flemish miniaturist, a late example of the Flemish Primitives. He has been identified with the Master of James IV of Scotland.
Gerard Horenbout lived and worked in Ghent as a manuscript illustrator and a painter. First mentioned in 1487, when he joined the guild of Saint Luke, he had at least two apprentices, one in 1498, and one in 1502. In 151, he was made painter to Archduchess Margaret of Austria, and also briefly worked at the court of Henry VIII in England. He was visited by Albrecht Dürer in 1521, when Dürer bought an illustrated manuscript made by his daughter Susanna Horenbout. His son Lucas Horenbout was also a well-known painter.[1]
