Never Quote Greek or French

Benjamin Disraeli, Endymion (Chp. 76):

“Hume was the first man who attacked the estimates. What are you going to do with yourself to-day? Will you take your mutton with me? You must come in boots, for it is now dinner-time, and you must return, I fancy. Twenty years ago, no man would think of coming down to the House except in evening dress. I remember so late as Mr. Canning, the minister always came down in silk stockings and pantaloons, or knee breeches. All things change, and quoting Virgil, as that young gentleman has just done, will be the next thing to disappear. In the last parliament we often had Latin quotations, but never from a member with a new constituency. I have heard Greek quoted here, but that was long ago, and a great mistake. The House was quite alarmed. Charles Fox used to say as to quotation—‘No Greek; as much Latin as you like; and never French under any circumstances. No English poet unless he had completed his century.’ These were like some other good rules, the unwritten orders of the House of Commons.”
