"Or call up him that left half told
The story of Cambuscan bold,
Of Camball, and of Algarsife,
And who had Canace to wife,
That own'd the virtuous ring and glass"
In these lines, the speaker alludes to "The Squire's Tale," one of the stories in Chaucer's "Canterbury Tales." It's an interesting choice, because "The Squire's Tale" is one of the stories Chaucer famously leaves unfinished. Before the Squire can finish telling his tale, the Franklin interrupts him and begins his own story. The conflict between the two characters mirrors the tension between "L'Allegro" and "Il Penseroso." As in "Canterbury Tales," Milton's speakers are giving speeches about who they are, while simultaneously trying to cut the other down.
