Bestir Thyself

Dante and Virgil ride on the back of Geryon depicted as an old and gigantic winged monster with a snake-like tail and paws of a lion. This picture illustrates the following passage:

…And said: “Now, Geryon, bestir thyself;
The circles large, and the descent be little;
Think of the novel burden which thou hast.”
(Inferno, Canto XVII)

The caption reads in the original French: Et aussitôt que je fus placé, il dit : ‘Géryon, tu peux partir.’
