Antinous Belvedere

Willem Danielsz. van Tetrode, known in Italy as Guglielmo Fiammingo, was a sixteenth-century sculptor of Dutch origin who served as a pupil of Benvenuto Cellini in Florence. On his return to Delft in the Netherlands in 1567–68, it has been suggested that he may have trained the young Adriaen de Vries and encouraged him to go to Florence.
