Italian architect and sculptor, active in Naples. Originating from a family of builders, he began his work by assisting Father Riccardo, who was working on the construction of a hospital near Lake Lucrino, in the village of Tripergole, later destroyed by the eruption of Monte Nuovo, the most recent volcano in Pozzuoli area. In 1306 Gagliardo worked for the construction of a thermal hospice for the poor, erected by the will of Charles II in the area between Pozzuoli and Arco Felice. His most important architectural work was certainly the church of Santa Chiara in Naples, built between 1310 and 1328, an example of Gothic-Provencal art. His precise and individual architectural style influenced also the Sienese Tino di Camaino with whom he had intense collaboration in the realization of the sculptures of the sepulchre of Mary of Hungary in the church of Santa Maria Donnaregina in Naples. //
