Miscellaneous information
"[...] Galileo, born in 1564 and destined to become one of the greatest scientists in history (and also a skilled lutenist who, according to his biographer Vincenzo Viviani, „surpassed his own father in grace and charm of playing the lute“)." Douglas Alton Smith, s.a.
There is the possibility (without any evidence) that a single sheet might contain a work (Ricercare) from Galileo Galilei, despite the fact that the Library catalogue attributed it to "Vincenzo Juniore", compare Dinko Fabris, s.a., p.72.
