Saint Aengus (- 824)

He was born near Clonenagh and educated there at the monastic school founded there by St Fintan, not far from the present town of Mountrath. He lived for some time as a hermit and then joined the monastery of Tallaght, near Dublin, under St Maelruain. He was a co-author of a martyrology (written in 790 and the oldest in Ireland) and wrote a long poem, the Féilire, or Festology of the Saints, which he finished in about 805. After St Maelruain’s death he returned to his hermitage, where he died on 11 March 824.
