"Remember that this _Dyaush Pitar_ is the same as the Greek [Greek: _Zeus Patær_], and the Latin _Jupiter_, and you will see how this one word shows us the easy, the natural, the almost inevitable transition from the conception of the active sky as a purely physical fact, to the _Father-Sky_ with all his mythological accidents, and lastly to that Father in heaven whom Æschylus meant when he burst out in his majestic prayer to Zeus, _whosoever he is_" (510. 410). Unnumbered centuries have passed, but the "witchery of the soft blue sky" has still firm hold upon the race, and we are, as of old, children of "our Father, who art in Heaven." _Father-Sea._ Montesinos tells us that Viracocha, "sea-foam," the Peruvian god of the sea, was regarded as the source of all life and the origin of all things,--world-tiller, world-animator, he was called (509. 316). Xenophanes of Kolophon, a Greek philosopher of the sixth century B.C., taught that "the mighty sea is the father of clouds and winds and rivers." In Greek mythology Oceanus is said to be the father of the principal rivers of earth. Neptune, the god of the sea,--"Father Neptune," he is sometimes called,--had his analogue in a deity whom the Libyans looked upon as "the first and greatest of the gods." To Neptune, as the "Father of Streams," the Romans erected a temple in the Campus Martius and held games and feasts in his honour. The sea was also spoken of as _pater aequoreus_. _Father-River._ The name "Father of Waters" is assigned, incorrectly perhaps, to certain American Indian languages, as an appellation of the Mississippi. From Macaulay's "Lay of Horatius," we all know "O Tiber, Father Tiber, To whom the Romans pray," and "Father Thames" is a favourite epithet of the great English river. _Father-Frost._ In our English nursery-lore the frost is personified as a mischievous boy, "Jack Frost," to whose pranks its vagaries are due. In old Norse mythology we read of the terrible "Frost Giants," offspring of Ymir, born of the ice of Niflheim, which the warmth exhaled from the sun-lit land of Muspelheim caused to drop off into the great Ginnunga-gap, the void that once was where earth is now. In his "Frost Spirit" Whittier has preserved something of the ancient grimness. We speak commonly of the "Frost-King," whose fetters bind the earth in winter. In Russia the frost is called "Father Frost," and is personified as a white old man, or "a mighty smith who forges strong chains with which to bind the earth and the waters," and on Christmas Eve "the oldest man in each family takes a spoonful of kissel (a sort of pudding), and then, having put his head through the window, cries: 'Frost, Frost, come and eat kissel! Frost, Frost, do not kill our oats! Drive our flax and hemp deep into the ground'" (520.223-230).
