The Morall Fabillis of Esope the Phrygian is a work of Northern Renaissance literature composed in Middle Scots by the fifteenth century Scottish makar, Robert Henryson. It is a cycle of thirteen connected narrative poems based on fables from the European tradition. The drama of the cycle exploits a set of complex moral dilemmas through the figure of animals representing a full range of human psychology. As the work progresses, the stories and situations become increasingly dark.

Robert Henryson was a poet who flourished in Scotland in the period c. 1460–1500. Counted among the Scots makars, he lived in the royal burgh of Dunfermline and is a distinctive voice in the Northern Renaissance at a time when the culture was on a cusp between medieval and renaissance sensibilities. Little is known of his life, but evidence suggests that he was a teacher who had training in law and the humanities, that he had a connection with Dunfermline Abbey and that he may also have been associated for a period with Glasgow University. His poetry was composed in Middle Scots at a time when this was the state language. His writing consists mainly of narrative works. His surviving body of work amounts to almost 5000 lines.
