I know our mythic history, King Arthur's and Sir Caradoc's; I answer hard acrostics, I've a pretty taste for paradox, I quote in elegiacs all the crimes of Heliogabalus, In conics I can floor peculiarities parabolous; I can tell undoubted Raphaels from Gerard Dows and Zoffanies, I know the croaking chorus from The Frogs of Aristophanes!
