Tírechán

Tírechán was a 7th-century Irish bishop from north Connacht, specifically the Killala Bay area, in what is now County Mayo.

Based on a knowledge of Irish customs of the times, historian Terry O’Hagan has concluded that Tírechán was probably from a wealthy, elite family.

References to numerous geographical areas and to sites such as holy wells, cemeteries, crosses, and churches have led O’Hagan to call Tírechán one of the most "widely travelled" of early medieval writers.

[6] Eoin Mac Neill had assigned Tírechán as the author of Vita tripartita Sancti Patricii,[7] however, this has been roundly rejected.

The late seventh century witnessed a flourishing of Patrician literature as seen in Muirchú's Vita Patricii and the Liber Angeli.
