Huw Morus or Morys (1622 – 31 August 1709), also known by his bardic name Eos Ceiriog ("the nightingale of Ceiriog"), was a Welsh poet. One of the most popular and prolific poets of his time, he composed a large number of poems in a variety of metres. Morus's work bridges the gap between the strict-metre tradition of the Beirdd y Uchelwyr (the medieval "Poets of the Nobility") and popular verse.
