During the Roman Principate, the Roman Empire was divided into two parts: Senatorial Provinces and Imperial Provinces. Senatorial Provinces were governed by propraetors and proconsuls, who received no salary but received a portion of the tax revenue. Imperial provinces were governed by legatus augusti pro praetore or procuratores augusti, or in the case of Egypt, by a praefectus augusti. These were usually members of the equestrian order.
Equestrian's in government service where divided into three ranks: Vir Egregii, Vir Prefectissimo, and Vir Emminentissimo. Vir Egregii where further subdivided by salary into sexagenarii, centenarii, ducenarii, and trecenarii. procuratores augusti were members of the Vir Egregii, as were praefectus classis.
My questions are as follows:
What rank where the legatus augusti pro praetore? What rank was the praefectus Aegypt?
What was the salary of Vir Prefectissimo? What was the salary of Vir Emminentissimo?
What other government officials of each rank where there?
What were the salaries and ranks of praefectus cohorti, tribunus militum, and praefectus alae?
