The Thrissil and the Rois is a Scots poem composed by William Dunbar to mark the wedding, in August 1503, of King James IV of Scotland to Princess Margaret Tudor of England. The poem takes the form of a dream vision in which Margaret is represented by a rose and James is represented variously by a lion, an eagle and a thistle. The episodes of the poem present in allegory King James' view of himself and of his kingdom. Princess Margaret receives lavish praise for her beauty, virtue and high birth.
