The 'Decameron', also called 'Prince Galehaut', is a 14th-century medieval allegory by Giovanni Boccaccio, told as a frame story encompassing 100 tales by ten young people. The book's primary title exemplifies Boccaccio's fondness for Greek philology: Decameron combines two Greek words, Greek: déka («ten») and (Greek: hēméra («day»), to form a term that means «ten-day event». Ten days is the time period in which the characters of the frame story tell their tales.
