Together with Gasparo da Salò and Giovanni Paolo Maggini, Rogeri was one of the major makers of the Brescian school.
"Rogeri is believed to have been born in Bologna but moved to Cremona, where he was apprenticed to Nicolo Amati.
He reached his peak as a craftsman from about 1690 and his violins based on Amati's Grand Pattern are generally considered his best.
By 1690 he was aided by his son Pietro Giacomo, who was a skilled assistant, and no doubt helped with the production of some lesser instruments, which often have unpurfled backs.
The Rogeri workshop also produced a number of fine cellos that again demonstrate the benefit of a Cremonese education."
