Breviarium Romanum

The Breviarium is printed on columns, in Gothic characters that
alternate red and black. It is certainly the only copy of this edition
known in Italy. It is probably flanked by four others in the world. It
is unknown in which hands this Breviarium was in the past. A fairly
credible hypothesis is that it belonged, together with the Missale
Dominicanum, to the Blessed Osanna. Count Alessandro Magnaguti, the
former owner of the House, in one of his biography of the Blessed
Osanna, appeared in 1949, claims that the Missale and the Breviarium
"belong to the Blessed relic in the house ..." and declares that they
are certainly related to her. By giving the House to the Dominican
Order, the benefactor also gived the two incunabula.
