Willem Danielsz van Tetrode (1530-1587)

"Willem Danielsz. van Tetrode, known in Italy as Guglielmo Fiammingo (before c. 1530, Delft — after 1587), 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." - (Wikipedia (en) 13.10.2020)
