And now for my favorite mad Irishman:

Will o' the Wisp. Just so I can be on-topic, there's speculation that he was kinda spectrummy. Definitely not neurotypical, I'll grant you, in all the best ways. Well, except for the fascist sympathizing.

Time, that is intolerant
Of the brave and innocent
Worships language and forgives
Everyone by whom it lives.

Time, that with this strange excuse
Pardoned Kipling for his views,
And will pardon Paul Claudel,
Pardons him for writing well.
