De particula ex pretioso et viuifico ligno sacratissimae crucis Saluatoris Iesu Christi desumpta : sacris imaginibus et elogijs eodem ligno incisis insignita, et in Apostolico Sacrario asseruata commentarius
A scholarly commentary by Angelo Rocca, printed in Rome in 1609 by Guillelmus Facciottus, on a fragment of the True Cross and the sacred images cut into that same wood for the Vatican's apostolic reliquary. Its woodcut pictures show crucifixes of tall, narrow form, with the figure of Christ frontal, arms outstretched, and fine parallel hatching throughout, offering designers a model of severe devotional line and symmetrical composition.
