Section of Monolithic Railing with Bather and Lotus Medallions, c. 150-250. Railings demarcated a sacred space, such as a tree shrine or a stupa. Images associated with purifying waters were carved on the railings, as if to symbolically cleanse those who passed through the gate. Lotus and blue lily?flowers that grow in water?are the most common motif. Under a fruit-bearing tree is a young woman squeezing water from her hair. In a visual depiction of an ancient Indian poetic trope, a goose mistakes the drops of water for pearls and comes to eat them. In the windows above, carved on the coping stone, are two voyeurs and a bowl made of leaves filled with flower garlands, which would be used to adorn the sacred site.
