Forms
thēsaurārius (feminine thēsaurāria, neuter thēsaurārium); first/second-declension adjective[1] Also spelled thēnsaurārius.[1][2] Medieval spellings include tēszaurārius, thēsorārius and trēserārius.[3]
Etymology
It is from Latin thēsaurus (“treasure”) + -ārius.[1][4][3]
Earliest recorded meaning
Plautus has it in the Aulularia, in the phrase fures thesaurarii, “treasure thieves”.[1][4][5]
Semantic evolution
In Classical Latin it is a rare adjective meaning “of treasure”.[1][4] In Late Latin it became a noun for a treasurer, a keeper of a treasury, in Venantius Fortunatus and the letters of Isidore of Seville,[2][5] and the neuter thēsaurārium was used for treasure in Cassiodorus[4] and for a strongbox in Augustine.[6]
Medieval Latin used the noun for the treasurer of a king or of a church;[7][8] Du Cange cites Desiderius, treasurer of King Dagobert.[8] British sources also have the adjective for what contains treasure or is itself precious.[9] It lived on in Neo-Latin, where Ramminger quotes a treasurer of the Empire.[10] Köbler traces Middle Low German tesaurāriære to it.[3]
