Le pilote de l'onde vive, ou le secret du flux et reflux de la mer ...
Le pilote de l'onde vive is a 1678 French navigational treatise by Mathurin Eyquem du Martineau, published by Jean Dhoury, on the secret of the sea's tides and the pilot's use of them. The pictures are small woodcuts and engraved diagrams: a basket of flowers held up by two figures, a heraldic bookplate from the C.G. Jung library, and a page of tidal sphere geometry with zodiac signs around a circle. A designer might take the dense, symmetrical linework of the diagrams and the decorative emblem as models for compass-rose and ornamental border work.
