"Ektaxis kata Alanon" (Ἔκταξις κατὰ Ἀλανῶν) is a work of a now fragmentary nature; the title is translated as "Deployment against the Alani" or "The order of battle against the Alans" or referred to simply as "Alanica". It is thought not have been written as a presentation of facts but for literary reasons. Pertaining to the relevant historical facts, though, while governor of Cappadocia, Arrian repelled an invasion of the Alani sometime during 135 AD, a struggle in which Arrian's two legions were victorious.
