Missale romanvm, ex decreto sacrosancti Concilij Tridentini restitum
This is a 1575 Roman Missal printed by Christophe Plantin's workshop in Antwerp for use in Catholic liturgy after the Council of Trent. Its pictures are small woodcut historiated initials, red and black letters with scenes inside, showing figures in robes, a seated man, a kneeling praying figure, and soldiers or onlookers; a designer might borrow their compact framed-letter layouts and rust-red and black two-colour contrast.
