The Romans used the designation " Scythian " to denote many tribes regardless of ethnic origin and sometimes the term would be interchangeable with Goths ; the tribes attacking Anatolia was probably the Heruli who built ships to cross the Black Sea in 267 and ravaged the coasts of Bithynia @-@ Pontus besieging Heraclea Pontica . According to Syncellus , Odaenathus arrived at Anatolia with Hairan I and headed to Heraclea but the riders was already gone . They loaded the spoils onto their ships but many perished in a sea battle probably conducted by Odaenathus ; another possibility is that they was shipwrecked .
