Palladio and others incorporated an elongated Diocletian window in the form of an arched central light flanked by narrower, square-headed apertures.

Diocletian windows continued to be used occasionally in large public buildings in the various devolutions of Neoclassical architecture including the Beaux Arts movement (1880–1920).
