This map from 1668 shows two river islands in The Rhine that had been reclaimed into polders. The map is made by Isaac van Geelkercken, one of the three sons of Nicolaes van Geelkercken, who all three stepped into their father’s footsteps and made beautiful maps. It is 60 * 142 cm and made on sheets of paper that have been glued together.

The other polder is called The Maneswaard and is the only part of the municipality of Wageningen at the other side of the Rhine. The reason This map shows the reason: before the Rhine flew around The Maneswaard, and that was the municipal border. Nowadays The Maneswaard is more water than land. It has been excavated in search of sand, clay and pebbles.
