Giandomenico Gagini came from a family of sculptors originally from Bissone on Lake Lugano.
Part of the Gagini family was active in Northern Italy and another worked from the mid-15th century in Sicily and Calabria.
He immediately took up the family business, working in the field of statuary and architecture and in 1607 executed the Fontana della Ninfa (Fountain of the Nymph) in Militello, one of his many works.
He died in 1627.
