Focus on this artwork and explain the Restoration of the painting.
The Madonna della Loggia was not preserved in its best condition. Even the authenticity of Botticelli's works was doubted due to the poor conservation of the painting. His signature was found after the artwork was restored in 2004, which has revealed other details of the painting that were missing. Apparently, the artwork might have been set in a tabernacle frame, usually religious devoted massive frames, that emerged in Italy in 15th century. The Madonna della Loggia was supposedly made for "private religious devotion," so-called "colmi da camera."
