On today's date in 1837, the Princess Cristina Belgiojoso-Trivulzio scored the social coup of the season at her Parisian salon. Ostensibly, it was the culmination of a three-day charity fundraiser in aid of Italian political refugees, but it REALLY was the artistic equivalent of a prize fight—the fists in question pummeling the piano keyboard. If you'll forgive the pun, it was a "Battle of the HANDS," a digital confrontation of the two leading virtuoso pianists of the day, Sigismund Thalberg and Franz Liszt.

Thalberg was up first, playing his own Fantasy on Themes from Rossini's opera, "Moses." Liszt followed with one of HIS fantasias based on operatic themes. The music critic for the prestigious Journal des Debats was present, and he wrote, "Never was Liszt more controlled, more thoughtful, more energetic, more passionate. Never has Thalberg played with greater verve and tenderness. Each used every one of his resources. It was an admirable joust. The most profound silence fell over the noble crowd assembled, and, finally, Liszt and Thalberg were both proclaimed victors by this glittering and intelligent assembly. Thus: two victors and no vanquished."

When asked for her verdict who had "won" the contest, the hostess, Princess Cristina replied with consummate diplomacy: "Thalberg," she said, "is the first pianist in the world—Liszt is unique."
