A seal from Mohenjo-daro found by Wheeler in the 1920's. From his 1931 text: "The plant on the [seal] has been identified as a pipal tree, which in India is the Tree of Creation. The arrangement is very conventional and from the lower part of the stem spring two heads similar to those of the so-called unicorn."
