Forms

hōrārius (feminine hōrāria, neuter hōrārium); first/second-declension adjective[1][2] Also spelled ⟨orarius⟩.[1][2][3]

Etymology

It is from Latin hōra (“hour”) + -ārius.[4][1]

Earliest recorded meaning

Köbler's first record is from about 1150, in the British sources that Latham collected;[1] among them, the DMLBS quotes Robert Pullen's Sentences, which contrast eternal life with life that lasts only an hour.[3]

Semantic evolution

In the 12th century it meant lasting only an hour, short-lived:[3][2] Wolbero says that charity in the saints is not short-lived but lasting, and Peter of Trier says the same of the remorse of monks.[2] Albertus Magnus uses it for what belongs to an hour, beside diurnus, “daily”.[2] Later it meant marking the hours, of the hour lines of a clock or a dial,[3][5] and Copernicus uses it for the space of an hour.[5]

In the Church it referred to the canonical hours: Niermeyer records it of money paid as a fee for saying them,[4] and Erasmus, in a letter of 1520, speaks of the offices called hōrāria.[3] As a masculine noun it was a cleric who sang the hours, in a charter of Magdeburg of 1179 and at Chartres, where Du Cange gives the French heurier;[2][6][4] at Paris it was also the officer who paid the canons who attended the hours.[6] A medieval Greek glossary gives it for one who watches the hour of a birth, an astrologer.[6] The neuter noun hōrārium, a book of hymns for the hours, appears in Gottschalk the Saxon, although the manuscripts read ōrārium.[2] It is the source of Italian orario.[7]
