Adam of Bremen himself compared the sea with a belt, stating that it is so named because it stretches through the land as a belt (Balticus, eo quod in modum baltei longo tractu per Scithicas regiones tendatur usque in Greciam).
Pats Adomas Brėmenietis palygino jūrą su juosta, nes ji neva tęsiasi per žemę kaip juosta (Balticus, eo quod in modum baltei longo tractu per Scithicas regiones tendatur usque in Greciam).
