Dallán Forgaill was a 6th-century Irish poet and scholar who served as the Chief Ollam of Ireland. Born Eochaid, he earned the nickname Dallán, meaning little blind one, after losing his sight through intense study. He is highly regarded for his literary contributions to the early medieval Gaelic world, most notably his panegyric on Saint Columba. Throughout his life, he was a significant figure in the reform of the Bardic Order and founded several churches across Ireland due to his close ties with the clergy.
