In the folk-lore of the south Slavonian nations the serpent is regarded as a protective genius, not only of the people, but of domestic animals and houses as well. Every human being has a snake as tutelary divinity, with which his growth and well-being are closely connected, and the killing of one of these sacred creatures was formerly deemed a grave offense. To meet with a snake has long been accounted fortunate in some countries. The south Slav peasant believes that whoever encounters one of these creatures, on first going into the woods in the spring, will be prosperous throughout the year. But on the other hand he regards it as an evil omen if he happens to catch a glimpse of his own tutelary serpent. Fortunately, however, a man never knows which particular ophidian is his special guardian.[132] The relation of the serpent to sculptured or engraved stones reveals to us the reptile as still the object of veneration, if not of adoration, among widely remote nations. If we search among the tombs of Egypt, Assyria, and Etruria, we shall find innumerable signets, cylinders, and scarabei of gems engraved with serpents; these were proverbially worn as amulets, or used as insignia of authority; and, in the temples and tombs of these and other countries, serpents are engraved or sculptured or painted, either as hieroglyphics or as forming symbolical ornaments of deities or genii. In India they are sculptured twining around all the gods of the cave temples which mark the graves of kings and heroes, and the oldest of the Scandinavian runes are written within the folds of serpents engraved on stones.[133] In ancient Mexican temples the serpent symbol is frequently seen. The approach to the temple of El Castillo, at Chichen in Yucatan, is guarded by a pair of huge serpent heads, and a second pair protect the entrance to the sanctuary. Figures of serpents also appear in the Mosaic relief designs of the façades, and within on the sanctuary walls. So, too, in the temples of Palenque and other southern Mexican towns, serpents are everywhere plentiful in the decorations and sculptures.[134] Representations of snakes are to be seen on the walls of houses in many parts of India at the present day, and villages have their special ophite guardians. The fifth day of the first or bright half of the lunar month S’ravana, which nearly corresponds with August, is celebrated by the Brahmins in honor of the naga or cobra. Some interesting details of the ceremonies on these occasions are given in Balfour’s “Cyclopædia of India.” We learn from this source that native women are wont at such times to join in dancing around snake-holes, and also to prostrate themselves and invoke blessings; while others bow down before living cobras at their own homes, or worship figures of serpents.
