Sánchez Cotán's
Quince, Cabbage, Melon, and Cucumber makes a sort of visual sonnet.
The suspended quince and suspended cabbage form the octave, and the melon, slice, and cucumber form the sestet...
or maybe the three roundish items form quatrains, and the elongated slice and cucumber create a couplet...
or maybe I'm just making this up as I go along.
