What Bronzino painting supplied the giant foot in Monty Python's Flying Circus opening credits?

The giant foot in Monty Python’s Flying Circus opening credits comes from Bronzino’s painting Venus, Cupid, Folly and Time.

The painting was created by Agnolo Bronzino, a leading Florentine Mannerist active in the sixteenth century. Its crowded allegorical composition includes Cupid, whose foot was isolated and repurposed for Terry Gilliam’s collage-style animation. In the television opening, the oversized foot suddenly crushes the programme title, turning a Renaissance detail into one of comedy’s most recognisable visual signatures.

Gilliam’s animation drew heavily on paintings, engravings, Victorian illustrations and other found imagery. The deliberately mismatched scale—an enormous foot overwhelming the title—captures the series’ taste for abrupt, irrational visual jokes. The foot is sometimes casually called the “Foot of Cupid,” which can cause confusion with the name of the source painting.

Other famous opening elements include the brass-band performance of “The Liberty Bell,” a march by John Philip Sousa, and the old-fashioned title sequence. The alternatives in this question are paintings by Botticelli, Raphael and Sandro Botticelli respectively, not Bronzino’s source for the foot.
