On the left, that's "a spandrel on the southern facade of the Palazzo Ducale, Venice," to quote the February 14 issue of The New York Review of Books, which ran this picture the other day, curiously enough illustrating an essay on the late scientist Stephen Jay Gould. It turns out Gould had a thing or two to say about spandrels.
And on the right, a head shot of Chicago's own Picasso that ran in the February 4 Sun-Times. The caption noted that "some have guessed the sculpture . . . is a horse, an Afghan hound or a Viking Ship." Or had Picasso been thinking about Venice?
