Leonis Allatii, De Mensvra Temporvm Antiqvorvm et praecipue Graecorvm, Exercitatio
A 1645 Latin scholarly treatise by Leone Allacci on measuring ancient, especially Greek, time, printed for antiquarian and academic readers. Its pictures are small woodcut ornaments: a dense, symmetrical scrolled cartouche with foliage and a central knot, and a framed oval emblem with a winged cherub above a balance holding two globes beneath the word PRAESTAT, suggesting how a designer might borrow symmetrical frames and emblematic device layouts.
