One day it thrice over bit M.de Voltaire's own leg.

He had called it LUC (Luke); and in conversation with select friends, as also in Letters to such, he sometimes designated the King of Prussia by that nickname: 'HE is like my Luc here; bites whoever caresses him!'-- In 1756 M.de Voltaire, having still on his heart the Frankfurt Outrage, wrote curious MEMOIRES [ah, yes, VIE PRIVEE]; and afterwards wished to burn them; but a Copy had been stolen from him in 1768,"-- and they still afflict the poor world.
To the same effect speaks Johannes von Muller: "Voltaire had an Ape called Luc; and the spiteful man, in thus naming the King, meant to stigmatize him as the mere APE of greater men; as one without any greatness of his own."-- No; LUC was mischievous, flung stones after passengers; had, according to Clogenson, "bitten Voltaire himself, while being caressed by him;" that was the analogy in Voltaire's mind.

Preuss says, this Nickname first occurs "12th December, 1757." Suppose 11th December to have been the day of getting one's leg bitten thrice over; and that, in bed next morning,--stiff, smarting, fretful against the sad ape-tricks and offences of this life,--before getting up to one's Works and Correspondences, the angry similitude had shot, slightly fulgurous and consolatory, athwart the gloom of one's mood?
