Not only was a tree the earliest house of man, it was also his first temple. That very word “temple” bears witness to the fact, for it is from the Greek τέμενος, a sacred grove set apart as a place of worship. The aspiring lines of Gothic cathedrals simulate the trunks of slender and majestic trees carrying the eye and the soul aloft, and by their overreaching limbs shutting out the glare of day, thus leading the mind to holy meditation. Tacitus describes the Germans as building no temples, but worshipping their mysterious divinity, _secretum illud_, in the gloom of the forest. _5. Places and Sites._—Early man stays close to the soil. It is proved, by the distribution of the oldest stone implements, that primitive tribes were not generally migratory, and had little intercourse with their neighbours. Hence the more closely did they study their immediate surroundings; and a spot which was marked by some peculiar feature was soon associated with their all-permeating religious notions, and was deemed sacred. These features can usually be easily recognised. A spring, well, or fountain, where from dry earth, or out of the rock, pours forth the crystal fluid on which depends the life of man and brute and plant, was everywhere a holy spot. The brook which flowed from it, chattering its endless tale among the pebbles, was scarcely less so. It was directly said and oft repeated by the Greeks that the _manteia_, the holy inspiration, was imparted at the fountain of Parnassus or at the Pierian spring. The Moxos of Bolivia claim descent from the stream on which their villages are situated, a more than figurative expression of their dependence on it for food and drink.[192] The sacred character of “high places,” such as hills, mountains, or elevated plateaux, is intimately connected with the universal belief in “the Father in Heaven,” the sky as the home and the throne of the greatest divinities. I have already referred to the terrestrial “Hills of Heaven,” located, as a rule, within the tribal area.[193] A high hill or mountain, regarded by itself as a personality, would justly be looked upon as of extraordinary might, and invoked as a potent aid in the undertakings of life. In the invocations of the Quiches of Central America, who live in the midst of lofty peaks, over one hundred of them are named and implored for aid. The “Heart of the Hills” is the title which the ancient Mexicans applied to one of their greatest gods. A third and important trait which gave them sacredness is the strength of the echo which is returned from their narrow gorges or precipitous sides. Mountain worship is very generally oracular in character. Classical and familiar examples of this are the Pythoness and the Roman Sibyl.
