Illustration 4: 1731 VOC list <strong>of</strong> instruments and <strong>chart</strong>s for Chamber Zeeland
The fact that not all ships followed <strong>the</strong> prescribed sailing instructions, is demonstrated by <strong>the</strong> 1726 disaster <strong>of</strong> <strong>the</strong> Ravensteyn. Against <strong>Company</strong> regulations, this Zeeland Chamber ship sailed along <strong>the</strong> west side <strong>of</strong> <strong>the</strong> Maldives and ran aground on an outer reef <strong>of</strong> <strong>the</strong> Ari-atol. This catastrophe is mentioned on our <strong>chart</strong>: Ravensteyn gebleven (Ravensteyn lost here). This reference is only present on our <strong>chart</strong> – as is <strong>the</strong> case with <strong>the</strong> loss <strong>of</strong> <strong>the</strong> Zeewijck. Being <strong>chart</strong>maker <strong>of</strong> <strong>the</strong> Zeeland Chamber, Abraham <strong>An</strong>ias gave full attention to this Zeeland calamity, as a matter <strong>of</strong> fact he even drew a detailed <strong>chart</strong> <strong>of</strong> <strong>the</strong> Ari-atol in 1728 (see ill.2). The wide-spread trading network <strong>of</strong> <strong>the</strong> VOC also stretched into <strong>the</strong> northwestern corner <strong>of</strong> <strong>the</strong> <strong>India</strong>n Ocean, where <strong>the</strong> <strong>Company</strong> had trading-posts in Suratte, in <strong>the</strong> Persian Gulf and in Mocha. From Suratte <strong>the</strong> VOC ships sailed via Strait Hormus to Gamron in <strong>the</strong> north <strong>of</strong> <strong>the</strong> Persian Gulf and to Basra on <strong>the</strong> Shatt-al-Arab. The sou<strong>the</strong>rn part shows <strong>the</strong> ‘Isola de Barein’ (Bahrain). While <strong>the</strong> Gulf was significant for <strong>the</strong> silk trade, later <strong>the</strong> trade in gold was more <strong>important</strong>.
