Old English poetry also contained a wide range of conventional poetic diction, many of the words being created to allow alliterative patterns to be made. There are therefore numerous alternatives for key words like battle, warrior, horse, ship, the sea, prince, and so on. Some are decorative periphrases: a king can be a 'giver of rings' or a 'giver of treasure' (literally, a king was expected to provide his warriors with gifts after they had fought for him).
