A king disguised as a bard in the fantasy short story "The Quest of the Queen's Tears" from The Book of Wonder, 1912, by Lord Dunsany.
He hopes to play a song so sad it will make Queen Sylvia weep, and thereby win her hand.
And there was one, Ackronnion, clothed with rags, on which was the dust of roads, and underneath the rags was war-scarred armour whereon were the dints of blows; and when he stroked his harp and sang his song, in the gallery above maidens wept, and even old lords chamberlain whimpered among themselves and thereafter laughed through their tears and said: "It is easy to make old people weep and to bring idle tears from lazy girls; but he will not set a-weeping the Queen of the Woods."
And graciously she nodded, and he was the last. And disconsolate went away those dukes and princes, and troubadours in disguise. Yet Ackronnion pondered as he went away.
King he was of Afarmah, Lool and Haf, over-lord of Zeroora and hilly Chang, and duke of the dukedoms of Molong and Mlash, none of them unfamiliar with romance or unknown or overlooked in the making of myth. He pondered as he went in his thin disguise.
The name is also mentioned in the 1989 short story "The Edge of the World" by Michael Swanwick, in Full Spectrum 2 and collected in Gravity's Angels.
