you read the account given by Kinsella. There are authors today that go even further than Kinsella did in the same tradition, both Morgan Llywelyn and Gregory
Frost, make the characters of the Ulster Cycle breathe and speak much like they may have done before they were blanketed by the censorship of Christianity, that is, before they were anglicized. Right, back to the tale:

Maeve led her army southeast from Cruachan Ai through many lands by the river Cronn till they set

camp at Cuil Silinne. During this initial advance, she had noticed that there was one particular division of men who out did the other troops in everything. When the others were just pitching camp, these men of the Gallion of Leinster had already finished and were sitting down to eat and listen to their harpers play. By the time the others had finished eating, the Gallion were already asleep. Even Leinster slaves were more proficient than the slaves of the others. Maeve felt her skin chill as she approached Ailill.
