328 THE ARCTIC HOME IN THE VEDAS. referring to 360 days, divided into four groups or seasons of 90 days each. This is good evidence to hold that the yearly course of the sun must be taken as the basis of the exploits of Viṣhṇu. The Ṛig-Veda further tells us that Viṣhṇu was the intimate friend of Indra (yujyaḥ sakhâ, I, 22, 19), and that he assisted Indra in his fight with Vṛitra. Thus in IV, 18, 11, we are told that " Indra about to kill Vṛitra said ' O friend Viṣhṇu ! stride vastly,' (also cf. VIII, 12, 27)"; and . in I, 156, 4, Viṣhṇu is said to have opened the cows' stable with the assistance of his friend, while both Indra and Viṣhṇu are described as having together vanquished Shambara, conquered the host of Varchins and produced the sun, dawn and the fire in VII, 99, 4 and 5. It is evident from these passages that Viṣhṇu was the associate of Indra in his fight with Vṛitra (cf. VIII, 100, 12); and if so, one of the three steps must be placed in regions where this fight was fought, that is, in the nether world. We can now understand why, in I, 155, 5, it is said that two of the three steps of Viṣhṇu are visible to man, but the third is beyond the reach of birds or mortals (also cf. VII, 99, 1). When the third step of Viṣhṇu is located in the nether world, it can well be said to be invisible, or beyond the reach of mortals. We have seen that the abode of Vṛitra is said to be hidden and filled with darkness and waters. If Viṣhṇu helped Indra in his fight with Vṛitra, his third step must be taken to correspond with the home of Vṛitra ; in other words, Viṣhṇu's strides represent the annual course of the sun divided into three parts. Dur- ing two of these the sun was above the horizon, and hence two of Viṣhṇu's three strides were said to be visible. But when in the third or the last part of the year the sun went below the horizon producing continuous darkness, Vi- ṣhṇu's third step was said to be invisible. It was then that he helped Indra to demolish Vṛitra and bring back the dawn, the sun and the sacrifice. It has been shown in the last
