Mādhava’s Lagnaprakaraṇa is an important astronomical text which discusses numerous innovative techniques of precisely determining the udayalagna or the ascendant. In previous papers, we have detailed the various methods of determining the ascendant described in the second and third chapters of this text. In this paper, we discuss a technique described in the fifth chapter, which makes use of two quantities known as the viṣuvannara and the ayanāntaśaṅku.
