Water is symbolised by a mermaid sitting among reeds and bulrushes with a sphere in her hand. Her arm is supported by an urn from which water gushes. At the bottom of her tail are shells. Behind her is the trident of the sea god Neptune.
Additional information:
The sphere refers to the waters covering the Earth, while Neptune’s trident alludes not only to the sea god’s dominion over the oceans, but also to the fact that at that time the Dutch ruled the seas.
