What is the X in X-mas?
1823, pertaining to or resembling British poet George Gordon, 6th Baron Byron (1788-1824).
Perfect she was, but as perfection is
Insipid in this naughty world of ours,
Where our first parents never learn'd to kiss
Till they were exiled from their earlier bowers,
Where all was peace, and innocence, and bliss
(I wonder how they got through the twelve hours),
Don Jose like a lineal son of Eve,
Went plucking various fruit without her leave.
[from "Don Juan"]
