As a physician he cured a few but he was restlessly looking for the two Venetian gun - makers. Casually he got into a factory, where says Varthema in his travel accounts, a hug brass cannon was being moulded by the two Italian gun - makers. Privately he asked them in their own tongue what mischief they were doing against the Portuguese. They assured him that they were careful in making less powerful cannon than those possessed by the Portuguese. The were happy that the Zamorin and his officials were very kind to them and were highly paid. They were married locally and were granted comfortable dwellings. They were so well guarded that escape was impossible.

A local Arab priest who felt jealous of the Egyptian's influence over their ruler, was keenly watching the movements of the Fakir and he succeeded in finding out that he was in league with a Persian trader who with Yunus was about to leave the harbour without paying port dues. The Persian was arrested by the coastal guards, but Varthema cleared off in the dark getting into a small yacht which took him back to Cochin.

In the mean - time the two gun - makers tried to escape with all the precious stones they had collected, having sent their wives a day earlier. They were caught somewhere near Tellicherry by the hirelings of the Arab priest, who killed and robbed the gun - makers in spite of the warning of the Zamorin to bring them back alive.

Varthema says that at this time, 1504, Calicut was a silent port on account of the Portuguese ships' depredations of the Arab ships visiting Calicut. It was almost under a blockade.

Varthema went to Ceylon where he met his old Persian friend whose niece he had married. Together they visited Burma and Malaya and after two years returned to Aden. Here they parted company and Varthema sailed through the Red sea and again to Boulogne, reaching home in 1508: He published the famous historical book. "The itinerary of Ludovico de Varthema of Boulogne from 1502 to 1508:. It was this book that fired the imagination of adventurous navigators from Spain, Holland. France and England and led to several discoveries and conquests of hitherto unknown countries.
