But when the winters were short they corresponded with, and were confined only to, the long night ; while at the present day, since the winter in the Arctic regions lasts for ten months, the long night falls in the middle of such winter. The description of the Airyana Vaêjo in the Vendidad, therefore, naturally leads us to infer that ten months sunshine or summer followed by two months dark winter represented the climatic conditions of the place before the inva- sion of Angra Mainyu, who converted summer into winter and vice versa, by introducing ice and snow into the land. We have already referred to the maximum period of a hundred nights during which Tishtrya fought with Apaosha, and to the custom of keeping the dead bodies in the house for two nights, three nights or a month long in winter, until waters and light, which stood still in winter, again began to flow or come up, showing that the period was one of continuous darkness. These passages taken in conjunction with the aforesaid description of the Airyana Vaêjo clearly establish the fact that the paradise of the Iranians was situated in the extreme north or almost near the North Pole, and that it was characterised by long delightful summers, and short and warm but dark winters, until it was rendered unfit for human habitation by the invasion of Angra Mainyu, or the advent of the Glacial epoch, which brought in severe winter and snow causing the land to be covered with an icecap several hundreds of feet in thickness.

Dr. Haug thinks that the paragraph "The latter are cold as to water etc." is also a later addition, and must, therefore,
