In Coleman's Mythology of the Hindoos, p. 202, it is written: "On the Buddha's foot is the mark called the 'chakravarti,' wheel or discus, which should have been on the palm of the hand, by which the sages at his birth divined that he would rise to considerable eminence." He says (p. 19): "Various data have been assigned to the period of Buddha's existence. The most correct seems to be about 550 B.C., whence, as the sages practised cheiromancy at Buddha's birth, its existence must have been much earlier known among the Indians."
