A person who writes elegies; a poet who specializes in composing mournful or contemplative verses.
From elegy (Greek elegeia) plus the agent suffix -ast (meaning 'one who does'). Similar to the suffix -ist, -ast creates nouns describing a person practicing a particular art or craft.
An elegiast is basically a professional mourner in poetic form—think of them as the ancient equivalent of a songwriter who writes all the sad breakup songs everyone loves.
