Quaestiones de tribus principiis rerum naturalium : [With 4 treatises by Franciscus de Mayronis, and one by Thomas Aquinas].
A late medieval scholastic philosophy volume by Antonius Andreae, a Franciscan writer of around 1320, on the three principles of natural things, with treatises by Franciscus de Mayronis and Thomas Aquinas. The single picture is a printer's or owner's mark: a black panel with a white cross above a cloud-scalloped roundel holding the letters L, R and F, framed by a thin double border, a bold high-contrast device a designer could adapt for a monogram or emblem.
