In one of the most famous paintings in the Uffizi Gallery in Florence, Italy, Federico da Montefeltro gazes at his wife, Battista Sforza, as they stand in front of the landscape over which they ruled.

Undulating hills rise to volcano-like peaks on which towns perch. The ragged Apennine mountains stalk the horizon, and what's thought to be the Metauro river swirls below.
Painted by Piero della Fran
