Vicarius

Vicarius is a Latin word, meaning substitute or deputy. It is the root and origin of the English word "vicar" and cognate to the Persian word most familiar in the variant vizier.

Originally, in ancient Rome, this was an equivalent to the English "vice-" (as in "deputy"), used as part of the title of various officials. Each vicarius was assigned to a specific superior official, after whom his full title was generally completed by a genitive (e.g. vicarius praetoris). At a low level of society, the slave of a slave, possibly hired out to raise money to buy manumission, was a servus vicarius.^[1]

Later, in the 290s, the Emperor Diocletian carried out a series of administrative reforms, ushering the period of the Dominate. These reforms also saw the number of Roman provinces increased, and the creation of a new administrative level, the diocese. The dioceses, initially twelve, grouped several provinces, each with its own governor. The dioceses were headed by a vicarius, or, more properly, by a vices agens praefectorum praetorio ("deputy of the praetorian prefect"). An exception was the Diocese of Oriens, which was headed by a comes ("count").

According to the Notitia dignitatum (an early fifth century imperial chancery document), the vicarius had the rank of vir spectabilis; the staff of a vicarius, his officium, was rather similar to a gubernatorial officium. For example, in the diocese of Hispaniae, the his staff included:

• The princeps (i.e. chief) of the schola (imperial guard unit) of the agentes in rebus (couriers), from the salary class of the ducenarii(those earning 200,000 sesterces a year - the highest regular pay grade in the Roman civil service).
• A cornicularius ("chief of staff").
• Two numerarii (chief accountants).
• A commentariensis(keeper of the commentary," the official diary).
• An adiutor (adjutant; literally "helper," an assistant).
• An ab actis ("acts-keeper," archivist).
• A cura epistolarum ("curator of correspondence").
• An unnamed number of subadiuvae ("deputy assistants").
• Various exceptores (lower clerks).
• Singulares et reliquum officium (various menial staff).
