Flavius Castinus was an influential Roman general and politician at the court of Emperor's'Honorius andValentinian III, and most likely for some time before. He played a role in several military campaigns in Gaul and Hispania. He held the position ofpatricius and also served asconsul for the year 424.
Castinus had the rank ofcomes domesticorum, commander of an elite unit in theRoman army underConstantius III. It has been recorded that he campaigned against theFranks, possibly as a general.[1] It is certain that he had that rank in421.
In 422 he fought an unsuccessful campaign inHispania to subdue theVandals. He was sent to support theSuevi or Suebians, enemies of the Vandals, and came with a force of Gothicfoederati. However, the campaign was compromised at the very beginning when, according to one source, "his haughty and inept exercise of command" led to a quarrel between him and the military tribuneBonifacius, a protégé of EmpressGalla Placidia. Bonifacius abruptly left the expedition, eventually arriving in Africa, where he began to build up a power base. Castinus continued on to Hispania, where at first he had considerable success against the Vandals inBaetica, managing to put them under a blockade and coming close to forcing them to surrender. Unfortunately at this point the Gothic auxiliaries betrayed him in some unspecified manner, which led to his defeat inBaetica. Castinus was forced to fall back to Tarraco (Tarragona).[2]
The sudden death of the nonentity Emperor Honorius 15 August 423, which followed the death of the more activeConstantius III (421) and the exile of Empress Galla Placidia toConstantinople (Spring 423), created a power vacuum "if it can be so described", observes John Matthews, which "was filled, as we should expect, by usurpation."[3] TheEastern EmperorTheodosius II hesitated to nominate a new emperor of theWest; Stewart Oost points out that with Honorius' death, "technically and legally he became sole ruler of the whole Roman Empire". Oost also argues that Theodosius reached an agreement with Castinus, where Castinus would act as his vice-regent in the West and in return Theodosius appointed Castinus and the Easterner Victor consuls for 424.[4] If such an agreement was made, Castinus broke it when he joined in declaringJoannes, the senior civil servant, as the new Western Emperor in late 423.[3]
Joannes was an insecure emperor. The Emperor Theodosius invested his young cousinValentinian III with the honor of Caesar the next year, then dispatched an army against Joannes. The usurper was captured and executed in June/July 425.[5] Castinus's role in these events is unknown; Oost notes of his "acts during the usurper's reign we hear absolutely nothing."[6] Matthews succinctly states that Castinus was sent into exile;[7] while agreeing with Matthews, Oost adds that a "doubtful source says that he found refuge in theChristian magnanimity of another old foe,Count Boniface of Africa."[6]
