De orbis terrae concordia libri quatuor : multiiuga eruditione ac pietate referti, quibus nihil hoc tam perturbato rerum statu uel utilius, uel accommodatius potuisse in publicum edi, quiuis aequus lector iudicabit
A Latin treatise on world religious concord by Guillaume Postel, printed by Johannes Oporinus at Basel in 1544 for scholarly and theological readers. The pictures are woodcut initial letters set in square blocks: profile heads in helmets and hoods, acanthus and oak corners, scrolling banderoles, and figures climbing the letterform, all hatched against dense line grounds.
