More difficult than the question of the beginning of the Quaestorship of Cassiodorus is that of its duration and its close. It was an office which was in its nature an annual one. At the commencement of each fresh year 'of the Indiction,' that is on the first of September of the calendar year, a Quaestor was appointed; but there does not seem to have been anything to prevent the previous holder of the office from being re-appointed. In the case of Cassiodorus, the Quaestor after Theodoric's own heart, his intimate friend and counsellor, this may have been done for several years running, or he may have apparently retired from office for a year and then resumed it. It is clear, that whether in or out of office he had always, as the King's friend, a large share in the direction of State affairs. He himself says, in a letter supposed to be addressed to himself after the death of Theodoric[33]: 'Non enim proprios fines sub te _ulla dignitas_ custodivit;' and that this was the fact we cannot doubt. Whatever his nominal dignity might be, or if for the moment he possessed no ostensible office at all, he was still virtually what we should call the Prime Minister of the Ostrogothic King[34]. [Footnote 33: ix. 24.] [Footnote 34: Thorbecke has pointed out (pp. 40-41) that we possess letters written by Cassiodorus to four Quaestors before the year 510, and that therefore the fact of others holding the nominal office of Quaestor did not circumscribe his activity as Secretary to Theodoric.] [Sidenote: Consulship of Cassiodorus, 514.] In the year 514 he received an honour which, notwithstanding that it was utterly divorced from all real authority, was still one of the highest objects of the ambition of every Roman noble: he was hailed as Consul Ordinarius, and gave his name to the year. For some reason which is not stated, possibly because the City of Constantinople was in that year menaced by the insurrection of Vitalian, no colleague in the East was nominated to share his dignity; and the entry in the Consular Calendars is therefore 'Senatore solo Consule.'
