Gerard Horenbout or Gerard Hourenbout (c. 1465–c. 1541) was a Flemish miniaturist, a late example of the miniature tradition in Early Netherlandish painting. He is "likely and widely accepted" to be the Master of James IV of Scotland, a leading miniaturist of the period, responsible for the Spinola Hours and other major projects of the last flowering of the Flemish miniature tradition.[1][2]
