Bartolomeo Massari (c. 1596 – 18 February 1655) was an Italian painter turned astrological doctor and anatomist.
A painting that he made in the Church of St. Martino Maggiore in Bologna in 1625 is titled "St. Martin and the poor man".
He became an astrological doctor, prescribing based on horoscopes and then headed the Accademia de Notomia, a private academy in Bologna where he built up a group of nine students known as the 'Coro anatomico' ("anatomical choir") in 1650 who met and conducted anatomical studies.
His daughter Francesca married Marcello Malphigi but died shortly after.
[1][2] Massari died in Bologna and was buried in the church of St. Tommaso del Mercato which no longer exists.
