What happened 1773 AD

The person singing the lead role in Lucio Silla was a castrato named Venanzio Rauzzini in his late 20s. Mozart was especially fascinated with him, and he wrote him a three-movement motet, 'Exsultate, jubilate,' which women sopranos generally sing these days. To both composer and artist the last movement was a bit of a show-off. Mozart gave himself the challenge of setting only one term for the entire campaign, "Alleluia." Rauzzini would have loved it with its fast-paced and amazingly catchy vocal line. This was first heard on 17 January; at the Theatine Church in Milan in 1773. Exsultate, jubilate, for Mozart, is an important piece and one of the few pieces he wrote before adulthood that has remained among his most popular works.

Mozart paired with the grand old man of the world of libretto, the 74-year-old poet Metastasio. This wasn't an opera, this wasn't an oratorio, it was a 'dramatic serenade' that was performed successfully on May 1 of that year at the enthronement. Sadly, while it was definitely of high quality and certainly significant at the period, it has not survived the test of time to claim a place in the general repertoire.

Educational and technological reforms came about, including the establishment of higher education institutions such as the Istanbul Technical University.

Aimé Bonpland was born in La Rochelle, France, in 1858, and traveled with Alexander von Humboldt.
