his intent was to describe the tradition and set general aesthetic and linguistic standards for Scots poetic composition. As he was well aware, his own ancestor, James I, was a principal figure in that tradition. Some of the specific tenets of the royal treatise were not always observed by the Castalians, but its focus on language was a defining aspect for the group. James wrote elsewhere that it "best became a king" to "make famous his own tongue", and the Reulis and Cautelis seems principally designed to serve that aspiration. Yet James at the same time conscious of his increasingly likely future accession to the English throne also gave his publisher, Robert Waldegrave, permission to anglicise his Scots manuscripts when going to press for consumption in England.
