abbot. Supposedly of the royal O'Neill family of Ireland, he studied under David in his Pembrokeshire monastery of Menevia. One of his duties was bee-keeping: according to his Legend, a swarm of his bees settled on his ship when it was time for him to return to Ireland, whereby apiculture was introduced there. This is supported by his entry in the Martyrology of Oengus the Culdee (c.800): ‘in a little boat from the east over the pure-coloured sea my Domnoc brought…the gifted race of Ireland's bees.’ Modomnoc settled at Tibberaghny (Co. Kilkenny); some writers claim that he became bishop of (or at) Ossory. Feast: 13 February.
