Short answers, pulled from the story.
Giovanni Battista Tiepolo entered the world on the 5th of March 1696 in Venice. He received his baptism on the 16th of April 1732 at San Pietro di Castello, which served as the official cathedral of Venice at that time.
He began formal training as a pupil of Gregorio Lazzarini in 1710 but drew strong influence from Sebastiano Ricci, Giovanni Battista Piazzetta, Federico Bencovich, Tintoretto, and Veronese. A biography published in 1732 described how he departed from his teacher's studied manner to embrace a quick and resolute style full of spirit and fire.
Prince-Bishop Karl Philipp von Greifenclau zu Vollraths commissioned him to travel to Würzburg where he arrived there in November 1750 and remained for three years. During this time he executed ceiling paintings in the New Residenz palace including a massive fresco covering approximately 4,000 square feet finished in November 1753.
He suffered from jealousy and bitter opposition from Anton Raphael Mengs, rising champion of Neoclassicism. At instigation of Mengs' supporter Joaquim de Electa, King's confessor had Tiepolo's series of canvases for San Pascual church at Aranjuez replaced by works by Mengs' favorite.
Tiepolo died in Madrid on the 27th of March 1770. He is buried in Madonna dell'Orto in Venice.
