After studying metaphysics, logic and natural philosophy with Giuseppe Agostini (and after the usual four years of theology), he was sent to the Maronite college in Rome in 1615/16 – where he learnt Syriac.

He devoted himself till 1632 to the study and cultivation of ornamental plants, and published De Florum Cultura,[10] which was illustrated with copperplates by, amongst others, Anna Maria Vaiani, possibly the first female copper-engraver.
He published this at a time growing interest in and structural sophistication of seventeenth-century orangeries, constructed needed to protected citrus trees from the cold of Northern Europe or heat of Italian summers.
