The strange and inexplicable behaviour of animals in cases of fear, panic, or pain has been generally attributed by ignorant races to their possession by demons. Of this nature is the story of the devil entering the herd of swine and carrying them into the sea, related in the New Testament. It is said that even yet in some parts of Scotland the milkmaid carries a switch of the magical rowan to expel the demon that sometimes enters the cow. Professor Monier Williams writes from Southern India--'When my fellow-travellers and myself were nearly dashed to pieces over a precipice the other day by some restive horses on a ghat near Poona, we were told that the road at this particular point was haunted by devils who often caused similar accidents, and we were given to understand that we should have done well to conciliate Ganesa, son of the god Siva, and all his troops of evil spirits, before starting.' The same writer also tells us that the guardian spirits or 'mothers' who haunt most regions of the Peninsula are believed to ride about on horses, and if they are angry, scatter blight and disease. Hence the traveller just arrived from Europe is startled and puzzled by apparitions of rudely-formed terra-cotta horses, often as large as life, placed by the peasantry round shrines in the middle of fields as acceptable propitiatory offerings, or in the fulfilment of vows in periods of sickness. [92] This was the belief of the Corinthians in the Taraxippos, or shade of Glaucus, who, having been torn in pieces by the horses with which he had been racing, and which he had fed on human flesh to make more spirited, remained to haunt the Isthmus and frighten horses during the races.
