"Giovanni Antonio Galli, also called lo Spadarino (baptized January 16, 1585 – after June 1651) was an Italian Baroque artist who was a member of the Caravaggisti (followers of Michelangelo Merisi da Caravaggio).
He was born in Rome to a family originally from Florence. His activities are poorly documented but he is known to have been working in Rome in 1597. In 1616 he worked on the decoration of the Sala Regia in the Palazzo del Quirinale with Carlo Saraceni.
He was long confused with his lesser-known brother Giacomo Galli, a gilder, picture framer and artist. In 1943 the art historian Roberto Longhi identified Giovanni Antonio Galli as the painter of a number of works, based on stylistic comparison with The Miracle of Saint Valerie and Saint Martial, the artist´s only surviving documented work before the discovery of his frescoes in the Palazzo Madama." - (en.wikipedia.org 30.01.2020)
