Whose?

Answer 

is

Buddapada

This drawing was inspired by a stone tablet from Gandhara. But one of the biggest of such Padhas is found on top of Adam's peak, in Srilanka. The Buddhists claim that it was Buddha's footprint, Hindus think it is Shiva's, Muslims and Christians believe it is Adam's first footprint on Earth! 

Before sculptures of Budda came about, he was represented an-iconically (without form) through symbols like his feet, dhammachakra, an empty throne, parasol, etc, as it was not considered possible/appropriate to confine divinity to a form. Eventually, the sculptures came about, simple stupas become decorative, leading to the development of various regional artistic styles in the representation of Buddhist art. 

Most religions seem to have gone through this phase of aniconism. Early Christianity forbade any artistic representation of biblical themes, so much so that the initial biblical themes had to be simple and unreal, in spite of the great skills of the Greek and Roman artisans that were available at that point. In fact, it took another 1500 years for that glorious art to be revived back again, and came to be called the Renaissance. 

A conservative estimate that most scholars agree on is that the Vedas came to India in 1500 BCE, but you only find significant Hindu temples and sculptures being carved after 5 th century CE. So absolutely no evidence of representing divine anthropomorphic forms for about 2000 years. In fact, Buddhists had already been carving for at least 500 years before the Hindus started. It is probable that they were quite happy with their advanced literary corpus (Vedas) that they didn't find the need for or approve artistic representation of their Gods. Perhaps, it could have come about to counter the rising popularity of Buddhism.

Islam, of course, still bristles against any iconic representation of their divine, with serious consequences to the offenders. 

Buddha, of course, is considered as one of the Avatars of Vishnu by Hindus, who was supposedly born to mislead those who deny Vedic knowledge. Essentially undermining him, his followers, and his teachings, in my opinion. Such passive and active aggression/undermining by religions through mythology seemed to be quite common, with Buddhists and Jainas also having their own versions of Ramayana and Mahabaratha, to serve their own ends. There is even a Jataka story involving Krishna, called Ghata Jataka. 

Whilst Buddhism spread far and wide, it lost this fight for the hearts and minds of the people of India. So much so that by the 12 th century, except for some fringes, the foot prints of Buddhism had all but disappeared.
