According to some scholars, in the mid-460s, the Eastern Roman Emperor, Leo I, wanted to balance the weight of the Germanic component of the army, whose leader was the Alan "magister militum" Aspar. He thought that Tarasis and his Isaurians could be that counterweight, and called him, with many Isaurians, to Constantinople. This interpretation, however, has been contested. By the mid-460s, Arcadia and Zeno had been living at Constantinople for some time, where Lallis and Longinus also lived, the latter married to a Valeria, possibly a woman of aristocrat rank.
