How did Gregorio Lazzarini influence Giovanni Battista Tiepolo's early training?

Gregorio Lazzarini played a foundational role in the early training of Giovanni Battista Tiepolo. After Tiepolo’s father passed away in 1697, his mother entrusted the young artist to Lazzarini, who was a painter known for his decorative, academic style.1

Under Lazzarini’s guidance, Tiepolo was taught the essential techniques of the profession. This academic grounding provided the basis for Tiepolo's early work, which was characterized by a melancholic style and a strong emphasis on chiaroscuro—the dramatic use of light and shade—before he eventually transitioned toward the brighter, more vibrant color palettes that defined his later career.1
