(1) *Mānasāra* (Chap. VI, 1-120, named Śaṅku) : Rules are laid down on the principles of dialling and for ascertaining the cardinal points by means of a gnomon. The gnomon is made of some particular wood (lines 10-12, 106-108). It may be 24, 18, or 12 aṅgulas in length and the width at the base should be respectively 6, 5, and 4 aṅgulas (lines 13-22). It tapers from bottom towards the top (line 14). The rules are described (lines 23-88) ; but they are more explicit in the quotations given below. As regards the principles of dialling, each of the twelve months is divided into groups of ten days each, and the increase and decrease of shadow (or days, as stated by Vitruvius, *see* below) are calculated in these several parts of the different months.
