Some time before 1581, Giambologna made a set of small models on the theme of the 'Twelve Labours of Hercules'. Almost all of these statuettes were lost but, fortunately, bronze copies of them were executed at the request of successive Grand Dukes of Tuscany by some of Giambologna's pupils who inherited his workshop in Florence.
We are not sure of the name of the artist who made the present bronze. Recent scholars have suggested that it could have been Giovanni Battista Piamontini, a successful 18th-century Florentine sculptor who made this and other statuettes probably after casts modelled by Pietro Tacca, a favourite assistant of Giambologna.
The Gallery owns three more examples from the series of 'Hercules' Labours', all of which were purchased by Joseph Leeson, first Earl of Milltown, probably in 1744 or 1745, during his first trip to Italy.
