Dawe published a steady stream of poetry and other pieces, and still resides in Belfast. He was a member of Aosdána, the Irish Arts Academy. In the 1980s, Fiacc collaborated with Seamus Carmichael, who produced a series of color linoleum prints, three based on poems from the "Missa Terriblis" collection and 7 based on work from "Woe to the Boy".
