Sevenoaks and Shakespeare
Jack Cade( grammar-hating rebel leader) to Lord Saye( loyal courtier):
“ Thou hast most traitorously corrupted the youth of the realm in erecting a grammar school... It will be proved to thy face that thou hast men about thee that usually talk of a noun and a verb, and such abominable words as no Christian ear can endure to hear.”
Henry VI Part II, Act IV, Scene VII
Local tradition has it that the ruinous‘ grammar school’ in question is Sevenoaks, as Shakespeare based this particular plotline on actual events surrounding The Battle of Solefields( fought in 1450 on ground we now use as playing fields).
