Poor splendid Poet of the burning eyes 
And withered hair and godly pallid brow, 
Low-voiced and shrinking and apart wert thou,  
And little men thy dreaming could despise. 
How vain, how vain the laughter of the wise! 
Before thy Folly's throne their children bow-- 
For lo! thy deathless spirit triumphs now,  
And mortal wrongs and envious Time defies. 
 
And all their prate of frailty : thou didst stand 
The barren virtue of their lives above, 
And above lures of fame ;-- though to thy hand 
All strings of music throbbed, thy single love 
Was, in high trust, to hymn thy Gaelic land 
And passionate proud woes of Roisin Dubh.
Thomas MacDonagh
