Epact: Scientific Instruments of Medieval and Renaissance Europe

Giovanni Battista Giusti

Giovanni Battista Giusti was active in Florence during the second half of the 16th century, where he probably worked in the service of the Grand Duke, in the workshop that made scientific instruments for the Grand Ducal collection. Numerous quadrants and other measuring instruments which originally belonged to the Medicean collection bear his signature. Other instruments have been attributed to him.
