John Mor O'Dugan
From A Compendium of Irish Biography, 1878
O'Dugan, or O'Dubhagain, John Mor, a bard, who flourished in the 14th century, author of a topographical and historical poem of 880 lines, beginning, "Triallam timcheall na Fodhla" — (Let us go around Ireland). Edward O'Reilly says: "This poem gives the names of the principal tribes and districts in Meath, Ulster, and Connaught, and the chiefs who presided over them at the time Henry II. King of England was invited to this country by Dermod MacMorogh, King of Leinster. From the first line of this poem, and from the few ranns that this author has left us on the districts of the province of Leinster, it would seem that it was his intention to have given a complete account of all the districts and chief tribes in Ireland." [For account of the sequel to this work, see O'HEERIN.] He died in 1372, at the monastery of Rinn-duin (Randown, in the County of Roscommon), where he had spent the last seven years of his life.
