Birth and background

Antonio Lucio Vivaldi was born on 4 March 1678 in Venice, then the capital of the Republic of Venice. He was son of Giovanni Battista Vivaldi and Camilla Calicchio, as recorded in the register of San Giovanni in Bragora.

He was baptized immediately after his birth at his home by the midwife, the reason for which has led to speculation. It was most likely done due to his poor health. There is a false rumor that an earthquake struck the city that day. This rumor may have originated from an earthquake that struck Venice on 17 April 1688. The baptismal ceremonies which had been omitted were supplied two months later.

Vivaldi had five known siblings: Bonaventura Tomaso, Margarita Gabriela, Cecilia Maria, Francesco Gaetano, and Zanetta Anna. Vivaldi's health was problematic. One of his symptoms, strettezza di petto ("tightness of the chest"), has been interpreted as a form of asthma. This did not prevent him from learning to play the violin, composing, or taking part in musical activities, although it prevented him from playing wind instruments.
