Leonis ab Aitzema Historia pacis, a Fœderatis Belgis ab anno M DC XXI. ad hoc usque tempus tractatæ
A Latin history of the Dutch peace negotiations from 1621 onward, written by Lieuwe van Aitzema and printed in 1654 at Leiden by the Elsevier press for scholars and diplomats. Its pictures are ornamental printers' devices: a symmetrical strapwork band with grotesque masks, putti and scrolls, and a tapering filigree of spirals and loops that a designer could borrow for borders, dividers and headpieces.
