Carolus Clusius

Jacques de Gheyn trained as a glass painter, miniaturist, and ultimately as an engraver under Hendrick Goltzius. It was only around 1600 that he turned from printmaking to painting. Carolus Clusius, pictured here, was a French botanist who, in his later years, came to Leiden where his cultivation of tulips marked the beginning of the Dutch tulip-bulb industry.
