At the close of the tenth century story-telling was in high favour in Ireland, and the professional story-teller was able not only to recite any one of the great historical tales, but to improvise, if the occasion arose. Mac Coisse, the poet attached to the court of Maelsechnaill II., tells in an interesting prose work how his castle at Clartha (Co. Westmeath) was once plundered by the O’Neills of Ulster. He immediately set out for Aileach in order to obtain compensation from the head of the clan, King Domhnall O’Neill (d. 978). On his arrival, he was received with great honour and brought into the king’s presence. In response to Domhnall’s request for a story, Mac Coisse mentioned the names of a large number of tales including one called _The Plunder of the Castle of Maelmilscotach_. This was the only one with which the king was unfamiliar, so he asked the story-teller to relate it. In it Mac Coisse described, under the form of an allegory, the plundering of his castle by the king’s kinsmen. When he had finished he confessed that he himself was Maelmilscotach[241], and he begged the king to grant him full restitution of his property. This the king agreed to do, and the grateful poet then recited a poem of eighteen stanzas which he had composed about the king and his family.[242] III. The resemblance which we have noted between Icelandic and Irish customs seem to justify us in suggesting that they may be due in part to some influence exercised by the one people upon the other. There is in fact a certain amount of evidence which renders such influence probable. We know that Irish poets and story-tellers were welcome guests at the court of the Scandinavian kings in Ireland. In an elegy on Mathgamain, Brian’s brother,[243] one of the Munster bards, says he finds it difficult to reproach the foreigners because of his friendship with Dubhcena, Ivarr’s son.[244] And during the lifetime of Brian, Mac Liag, Brian’s chief poet, and Mac Coisse, poet and story-teller to Maelsechnaill II., visited the court of Sigtryggr and remained there for a whole year. On their departure they gave expression to their feelings of regret in a poetical dialogue:-- _Mac Liag_: It is time for us to return to our homes, We have been here a whole year; Though short to you and me may seem This our sojourn in Dublin, Brian of Banba deems it too long That he listens not to my eloquence.[245] Another poem of Mac Liag’s, in which he addresses the Scandinavians of Dublin as “the descendants of the warriors of Norway,” was also composed in Dublin, at the court of ‘Olaf of the golden shields,’ soon after the battle of Clontarf.[246]
