In any event he had become a priest against his own will, perhaps because in his day training for the priesthood was often the only possible way for a poor family to obtain free schooling. It is also possible that Vivaldi was simulating illness - there is a story that he sometimes left the altar in order to quickly jot down a musical idea in the sacristy. Though ordained a priest in 1703, according to his own account, within a year of being ordained Antonio Vivaldi no longer wished to celebrate mass because of physical complaints ("tightness of the chest") which pointed to angina pectoris, asthmatic bronchitis, or a nervous disorder.

The Four Seasons, a series of four violin concerti, is his best-known work and a highly popular Baroque piece. Antonio Lucio Vivaldi, nicknamed il Prete Rosso ("The Red Priest"), was a Venetian priest and Baroque music composer, as well as a famous virtuoso violinist he was born and raised in the Republic of Venice.
