Joh. Alphonsus Borellus ... De vi percussionis, et motionibus naturalibus a gravitate pendentibus, sive Introductiones & illustrationes physico-mathematicae apprimè necessariae ad opus ejus intelligendum De motu animalium unà cum ejusdem auctoris responsionibus in animadversiones ... Stephani de Angelis ad librum De vi percussionis
A 1686 Leiden-printed Latin treatise on physics and animal motion by the mathematician Giovanni Alfonso Borelli, issued by the publisher Petrus vander Aa for scholars of mechanics and anatomy. Its pictures are small woodcut and letterpress ornaments: three near-identical cartouches of scrolling foliage framing an open book and a shield with crossed keys, plus a vignette of a labourer with a spade inside a laurel wreath. A designer might take the dense, symmetrical scrollwork and the wreath framing as models for printed ornament and decorative borders.
