=========================================
Guillelmus Duranti (ca. 1237-1296) was a "canonist and one of the most important medieval liturgical writers."
He studied at Bologna under Bernard of Parma and then taught at Modena.
He spent most of his life in the service of the Pope.
RATIONALE DIVINORUM OFFICIORUM is his most famous work, first published by Fust and Schoeffer at Mainz in 1459.

Its eight parts contain a detailed account of the laws, ceremonies, customs, and mystical interpretation of the Roman Rite.
Book I treats of religious art and architecture: the church, altar, pictures, bells, churchyard, etc.;
II of the ministers;
III of vestments;
IV of the Mass;
V of the canonical hours;
VI of the Proprium Temporis;
VII of the Proprium Sanctorum;
and VIII of the astronomical calendar, manner of finding Easter, Epacts, etc.
[The] Rationale is the most complete medieval treatise of its kind; it is still the standard authority for the ritual of the thirteenth century and for the symbolism of rites and vestments"
