Amergin mac Eccit is a poet and warrior in the court of Conchobar mac Nessa in the Ulster Cycle of Irish mythology. He was the son of Eccet Salach, a smith, and grew to the age of fourteen without speaking or washing himself. One day Athirne, the Ulaid's chief poet, sent his servant to Eccet to order an axe. The servant was shocked when Amergin uttered a precocious, cryptic poem, and ran home to tell his master what he had heard.
