 Gabbiani’s masterpiece is considered to be his ceiling frescoes for the "Palazzina Meridiana", specifically in the "Sala Meridiana"' adjacent to the Pitti Palace and Boboli Gardens.This work underscores the frequent, yet somewhat ostentatious Medici patronage of arts related to science.The Salone was so named because it encased a Meridian line (a metal strip along floor and wall) with which one could make annotations of solar time, by noting where a beam of sunlight pointed at high noon.
