Giovanni Maria delle Piane (1660 – 28 June 1745) was an aristocratic Genovese who served as primary court painter for over 60 years in the late-Baroque period.

[1] In the Roman studio of Gaulli, Piane copied the works of great masters like Giulio Romano, Guido Reni, Annibale Carracci and Domenichino.

He gained loyalty from other peer aristocratic families, noting he adapted to the new sensitivity, with attention to the fashion of his subjects, styling them with "majestic and elegant drapes taking them in certain new and witty movements".

In 1709 he portrays Prince Antonio Farnese and the same year, he was nominated Court Painter in Parma from where, he returned to Genoa.

On April 21, 1711, Piane became the personal painter of Princess Elisabeth, receiving a stipend, including food and accommodation.

Between 1714 and 1715 he portrayed Princess Elisabeth when she married King Philip V of Spain, from 1715 until 1737, he mainly resided with the royal family in Piacenza.

Though already elder in 1737, he relocated to Naples, where he was retained for some years as court painter for the young king Charles III of Spain, already duke of Parma and his wife Maria Amalia of Saxony.
