The Nandipada ("foot of Nandi") is an ancient Indian symbol, also called a taurine symbol, representing a bull's hoof or the mark left by the foot of a bull in the ground.
[1] The Nandipada symbol also happens to be similar to the Brahmi letter "ma".
The Nandipada appears on numerous ancient Indian coins,[2] such as coins from Taxila dating to the 2nd century BCE.
The symbol also appears on the zebu bull on the reverse if often shown with a Nandipada taurine mark on its hump on the less worn coins, which reinforces the role of the animal as a symbol, religious or geographic, rather than just the depiction of an animal for decorative purposes.
The same association was made later on coins of Zeionises or Vima Kadphises.
