A roundel in heraldry is a disc; the term is also commonly used to refer to a type of national insignia used on military aircraft, generally circular in shape and usually comprising concentric rings of different colours.

In heraldry, a roundel is a circular charge. Roundels are among the oldest charges used in coats of arms, dating from at least the twelfth century. Roundels in British heraldry have different names depending on their tincture. Thus, while a roundel may be blazoned by its tincture, e.g., a roundel vert (literally "a roundel green"), it is more often described by a single word, in this case pomme (literally "apple", from the French) or, from the same origins, pomeis—as in "Vert; on a cross Or five pomeis" (Scottish Public Register vol. 32, p. 26).

In French blazon, a roundel of either metal (or or argent) is a besant, and a roundel of any colour (dark tincture) is a torteau, with the tincture specified.

One special example of a named roundel is the fountain, depicted as a roundel barry wavy argent and azure, that is, containing alternating horizontal wavy bands of blue and silver (or white). Because the fountain consists equally of parts in a light and a dark tincture, its use is not limited by the rule of tincture as are the other roundels.

Geoffrey Chaucer ( /ˈtʃɔːsər/; c. 1343 – 25 October 1400), known as the Father of English literature, is widely considered the greatest English poet of the Middle Ages and was the first poet to have been buried in Poet's Corner of Westminster Abbey. While he achieved fame during his lifetime as an author, philosopher, alchemist and astronomer, composing a scientific treatise on the astrolabe for his ten year-old son Lewis, Chaucer also maintained an active career in the civil service as a bureaucrat, courtier and diplomat. Among his many works, which include The Book of the Duchess, the House of Fame, the Legend of Good Women and Troilus and Criseyde, he is best known today for The Canterbury Tales. Chaucer is a crucial figure in developing the legitimacy of the vernacular, Middle English, at a time when the dominant literary languages in England were French and Latin.

Geoffrey Chaucer was born in London sometime around 1343, though the precise date and location of his birth remain unknown. His father and grandfather were both London vintners; several previous generations had been merchants in Ipswich. (His family name derives from the French chausseur, meaning "shoemaker".) In 1324 John Chaucer, Geoffrey's father, was kidnapped by an aunt in the hope of marrying the twelve-year-old boy to her daughter in an attempt to keep property in Ipswich. The aunt was imprisoned and the £250 fine levied suggests that the family was financially secure—bourgeois, if not elite. John Chaucer married Agnes Copton, who, in 1349, inherited properties including 24 shops in London from her uncle, Hamo de Copton, who is described in a will dated April 3, 1354 and listed in the City Hustings Roll as "moneyer"; he was said to be moneyer at the Tower of London. In the City Hustings Roll 110, 5, Ric II, dated June 1380, Geoffrey Chaucer refers to himself as me Galfridum Chaucer, filium Johannis Chaucer, Vinetarii, Londonie' .
