I noticed in Harry Potter and the Deathly Hallows that the witches and wizards of England decided to hide themselves from non-magical people in 1689–the year the Whigs nailed down their triumph inthe Glorious Revolution. See Michael Barone’s latest book, and Andrew Stuttaford’s review in NR a few issues back. It could be a poem by Yeats. “For the stars are shrunken And the sow won’t breed, Since the Whigs took magic,” The old man said. Song (from Cuchulain, the Killdeer, and the Beggar Maid)
The one and only.
