Shouldn't the city Antiocheia Eschate replaced by Alexandria Eschate. First as far as I know there was no city with such a name. The only one which would be close is Antiocheia in Scythia (Αντιόχεια της Σκυθίας). Also Alexandria Eschate was by far more important, well known and (most probably) bigger than Antiocheia in Scythia.
