Abstract

Cassiodorus, Jordanes, Ennodius and Marcellinus Comes offer quite different accounts of the battle between Ostrogoths and imperial troops which took place at Horreum Margi in 505. A careful study of these sources indicates that Theoderic and Anastasius were uneasy when mentioning the respective allies and that they both tried to hide the other’s involvement in the conflict. Ennodius’ mention of discordia is very important to understand both the causes and the consequences of Horreum Margi. In fact, Anastasius attacked an ally of Theoderic in order to show that the king was not willing to come to the rescue of his foederati. The Ostrogothic quick reaction led to an unforeseen conflict and opened a period of tense relations between Ravenna and Constantinople, whose end, a few years later, was sealed by Cassiodorus’ first letter, a document centered on the concept of concordia.
