Geoffrey Chaucer's squire from The Prologue of the Canterbury Tales is the son of the knight. He was a lover and a lively bachelor of about twenty years of age.
He was a man of moderate height and was wonderfully agile. He was very strong and had curly hair. He wore a short gown with long and wide sleeves.
Like his father, he had fought in many places - Flaundres, Artoys, and Pycardie - all on a cavalry expedition. He knew how to ride a horse well and how to make songs and write lyrics. He was a respectable jouster and a fair dancer. Drawing and writing came easy to him. He slept very seldom, as quoted, "He sleep namoore than dooth a nyghtyngale."
The squire was "courteous, humble, and willing to serve." He was carved before his father at the table. He conducted himself well for a man of only twenty years.
He was very respected and liked by everybody.
Chaucer must have liked the squire because he only said good things about him. There is no mentioning of anything bad in the text. He would be a good son, and the knight should be proud of him.
