"Jalis" (pierced screens) were used extensively in Indian architecture as windows, room dividers, and railings around thrones, platforms, terraces, and balconies. Used in outer walls, they were ideal for cutting down glare while permitting air to circulate. During the day the reflection of their patterns moving across the floor would double the pleasure of their intricate geometry. The architecture and weathering on one side suggest that this pair was probably part of a series of windows set in an outside wall.
