In medieval Ireland, bards were one of two distinct groups of poets, the other being the fili. According to the Early Irish law text on status, Uraicecht Becc, bards were a lesser class of poets, not eligible for higher poetic roles as described above. However, it has also been argued that the distinction between filid (pl. of fili) and bards was a creation of Christian Ireland, and that the filid were more associated with the church.^[7][8] By the Early Modern Period, these names came to be used interchangeably.^[9]

Irish bards formed a professional hereditary caste of highly trained, learned poets. The bards were steeped in the history and traditions of clan and country, as well as in the technical requirements of a verse technique that was syllabic and used assonance, half rhyme and alliteration, among other conventions. As officials of the court of king or chieftain, they performed a number of official roles. They were chroniclers and satirists whose job it was to praise their employers and damn those who crossed them.^[10] It was believed that a well-aimed bardic satire, glam dicenn, could raise boils on the face of its target.

The bardic system lasted until the mid-17th century in Ireland and the early 18th century in Scotland. In Ireland, their fortunes had always been linked to the Gaelic aristocracy, which declined along with them during the Tudor Reconquest.^[11]  – Wikipedia

This is 100% what Plato’s Curriculum teaches. Bards were Oralstorians and had ranks, with the Highest Order being able to recite on request any era, any tale at the drop of a hat. 

They were Philosophers and Scholars.
