Baile and Aillinn by W.B. Yeats

Argument. Baile and Aillinn were lovers, but / Aengus, the Master of Love, wishing them to be / happy in his own land among the dead, told to / each a story of the other's death, so that their / hearts were broken and they died.

I hardly hear the curlew cry, / Nor the grey rush when wind is high, / Before my thoughts begin to run / On the heir of Ulad, Buan's son, / Baile who had the honey mouth, / And that mild woman of the south, / Aillinn, who was King Lugaid's heir.
