In the vast Sinhalese demonology we find the highest class of demons (dewatawas) described as resident in golden palaces, glittering with gems, themselves with skins of golden hue, wearing cobras as ornaments, their king, Wessamony seated on a gem-throne and wielding a golden sword. Pluto is from the word for wealth (ploutos), as also is his Latin name Dis (dives). For such are lords of all beneath the sod, or the sea's surface. Therefore, it is important to observe, they own all the seeds in the earth so long as they remain seeds. So soon as they spring to flower, grain, fruitage, they belong not to the gods of Hades but to man: an idea which originated the myth of Persephone, and seems to survive in a school of extreme vegetarians, who refuse to eat vegetables not ripened in the sun. These considerations may enable us the better to apprehend the earlier characters of Ahi, the Throttler, and Vritra, the Coverer. As guardians of such hidden treasures as metals and drugs the Serpent might be baroneted and invoked to bestow favours; but those particular serpents which by hiding away the cloud-cows withheld the rain, or choked the rivers with drought, all to keep under-world garners fat and those of the upper world lean, were to be combated. Against them man invoked the celestial deities, reminding them that their own altars must lack offerings if they did not vanquish these thievish Binders and Concealers. The Serpent with its jewelled raiment, its self-renovating power, and its matchless accomplishments for lurking, hiding, fatally striking, was gradually associated with undulations of rivers and sea-waves on the earth, with the Milky-way, with 'coverers' of the sky--night and cloud--above all, with the darting, crooked, fork-tongued lightning. It may have been the lightning that was the Amrita churned out of the azure sea in the myth of the 'Mahábhárata,' when the gods and demons turned the mountain with a huge serpent for cord (p. 59), meaning the descent of fire, or its discovery; but other fair and fruitful things emerged also,--the goddess of wine, the cow of plenty, the tree of heaven. The inhabitants of Burmah still have a custom of pulling at a rope to produce rain. A rain party and a drought party tug against each other, the rain party being allowed the victory, which, in the popular notion is generally followed by rain. I have often seen snakes hung up after being killed to bring rain, in the State of Virginia. For there also rain means wealth. It is there believed also that, however much it may be crushed, a snake will not die entirely until it thunders. These are distant echoes of the Vedic sentences. 'Friend Vishnu,' says Indra, 'stride vastly; sky give room for the thunderbolt to strike; let us slay Vritra and let loose the waters.' 'When, Thunderer, thou didst by thy might slay Vritra, who stopped up the streams, then thy dear steeds grew.'
