Feb 5 Giovanni Battista Casti an Italian poet, satirist, and author of comic opera librettos, born in Acquapendente. He entered the priesthood after studying at the seminary of Montefiascone and became a canon in the cathedral of his native place, but gave up his chance of church preferment to satisfy his restless spirit by visiting most of the capitals of Europe. In 1784, after the death of Metastasio , he failed to be appointed Poeta Cesario, or poet laureate of Austria, and he left Austria in 1796. He spent the rest of his life in Paris, where he died in 1803. Casti is best known as the author of the Novelle galanti, and of Gli Animali parlanti, a poetical allegory, over which he spent eight years , which excited so much interest that it was translated into French, German and Spanish, and into English, in S. Rose's Court and Parliament of Beasts. Written during the time of the Revolution in France, it was intended to exhibit the feelings and hopes of the people and the defects and absurdities of various political systems. Some of Goya's print series The Disasters of War drew from the Spanish translation of 1813. The Novelle Galanti is a series of poetical tales, in the ottava rima metre largely used by Italian poets for that class of compositions. One merit of these poems is in the harmony and purity of the style, and the liveliness and sarcastic power of many passages
