[1] Upon his return, Pierre-Olivier Malherbe met several times with the French king Henry IV, to tell him about the gold and silver of the East Indies.
He explained about the routes to reach these places, and offered to lead an expedition for the king.
[1] Pierre-Olivier Malherbe may have been the author of a Malay language dictionary, which was added to François Martin de Vitré's work La Description du premier voyage fait aux Indes orientales par les Français en l'an 1603 in 1609.
[1] He is mentioned in the 1629 Traité de navigation et des voyages de découvertes et conquêtes, principalement des François by geographer Pierre Bergeron.
In Paris, he also met with the Dutch linguist Erpenius, who was preparing the first Latin–Arab Dictionary.
