Coastline profiles of Tuban Sidayu, Iurtan and Madura (East-Java)

After arriving in Bantam, four ships (the Gelderland, Zeeland, Utrecht and Amsterdam) of the Tweede Schipvaart (Second Expedition) continued eastwards to the Moluccas. In late January 1599, they anchored for about a week at Tuban. Tuban was the capital of a wealthy kingdom in East Java, near Surabaya, that was one of the most important trading ports in the region at the time. The leaders of the expedition met several times with the ruler of Tuban and visited his palace.

On the left page, the top profile shows what Heyndrick Derricksen Jolinck of the Amsterdam named the island of Tuban, which likely refers to the island Bawean which lies roughly opposite the city in the Java Sea. The second profile shows the Tuban mainland at about 7 miles distance. The third shows the same at about 2-3 miles distance. The final panel shows hills that could only be observed if the skies were clear.

On the right page,the top profile shows the city of Tuban when located to the south-southeast. The second shows an adjacent land. The third shows the island of Madura when the nearest point is 4 miles off the observer in east by north direction. The fourth shows the lands of Sidayu, near modern Surabaya, as seen when the nearest corner is south-southeast at about 2 ‘big miles’ distance. The fifth panel shows the lands behind Iurtan, which refers to the former Gresik trade district of Padjaratan according to J. Keuning. The final profile shows the eastern corner of Madura at 3,5 miles distance in east by south direction and a small neighbouring island.
