The general history of the air
This 1692 London natural-history treatise by Robert Boyle, published by Awnsham and John Churchill, is a scholarly work on the air and was issued for natural philosophers and readers of science. The single picture is a bookplate rather than an illustration of the text: an engraved coat of arms with a rampant lion crest, scrolling acanthus leaves, a diagonal-banded shield, and a banner reading John Hanbury of Pontypool in the County of Monmouth Esqr. 1704. A designer could take its symmetrical heraldic framing, scroll ornament, and engraved line work as a model for crests and ex libris panels.
