THERE ARE MANY stepwells in India. For those, who have never seen any of them, a stepwell is, putting it simply, an enclosure built around a deep well. Its walls have sets of staircases, often geometrically arranged with landings at regular intervals. The steps allow people to access the water, whose level varies according to the season. In rainy periods, the water level is high, but in other periods, it is far below ground level, and people use the steps to reach the it.

Whenever I see a stepwell, and I have seen many of them during travels in India, I think of the creations – optical illusions – of the Dutch graphic artist MC Escher (1898-1972). He produced images in two dimensions of subjects that cannot possibly exist in three dimensions. Several of his pictures include interconnecting staircases, which unlike those seen in stepwells, could not be constructed in three dimensional reality.

As far as I can establish, Escher never travelled to India. I always wonder if Escher’s staircase images were influenced by having seen drawings or photographs of stepwells in the Indian Subcontinent. It would be interesting to know if he did see pictures of these interesting water sources.
