   • 1867 July, William Dean Howells, “At Padua”, in The Atlantic Monthly: A Magazine of Literature, Science, Art, and Politics, volume XX, № CXVII, chapter i, page 25/1:

     I take shame to myself…for having been more taken by the salti mortali* of a waiter who summed up my account at a Paduan restaurant, than by all the strategies with which the city has been many times captured and recaptured.
     * Salti mortali are those prodigious efforts of mental arithmetic by which Italian waiters, in verbally presenting your account, arrive at six as the product of two and two.

   • 1919, Boris Sidis, The Source and Aim of Human Progress:

     The frenzied, suggestible, gregarious, subconscious self, freed from all rational restraints, celebrated its delirious orgies, its corybantic bacchanalia, held its mad salto mortale over the grave of crucified humanity.
