Les oeuvres de Ciceron de la traduction de Monsieur Du Ryer
A 1670 Paris edition of Cicero's works in Pierre Du Ryer's French translation, printed for the French-reading public and owned by John Adams, whose library survives at the Boston Public Library. The single plate is a frontispiece engraving of a heraldic achievement: a central shield with a saltire cross, flanked by two eagle-like supporters and topped by a crested eagle, set over a tiled floor. A designer could draw on its symmetrical armorial composition, its dense engraved line work and the ornamental scrolls framing the central emblem.
