Of beings, stars, and this unriddled wonder,The World, which at the worst's a glorious blunder—'- Who wrote these lines?

''For ever and anon comes Indigestion
(Not the most ''dainty Ariel'') and perplexes
Our soarings with another sort of question:
And that which after all my spirit vexes,
Is, that I find no spot where Man can rest eye on,
Without confusion of the sorts and sexes,
Of beings, stars, and this unriddled wonder,
The World, which at the worst's a glorious blunder—''

- Don Juan (Canto 11)
By Lord Byron.
