Vishpala is mentioned in the Rig Vedic hymns (Rig Veda 1.112, 1.116, 1.117, 1.118 and 10.39). The information we get from the text is that she lost her leg in Khela’s war (her leg was cut off like a wild bird’s pinion as mentioned in 1.116) and was granted a metal leg by the twin deities so that she can move/fight when the war starts again. The next hymn 1.117 mentions the great Rishi Agastya, implying that they graced her upon being invoked by him.
