restore fertility to barren livestock and act as a remedy to all poisons. Such is the devotion to frivolous affairs shown by many peoples.
Similar to the Sabine herb savin is a plant called selago. It must be picked without an iron instrument by passing the right hand through the opening of the left sleeve, as if you were stealing it. The harvester, having first offered bread and wine, must wear white and have clean, bare feet. It is carried in a new piece of cloth. The Druids of Gaul say that it is should be used to ward off every danger and that the smoke of burning selago is good for eye diseases. The Druids also gather a plant from marshes called samolus, which must be picked with the left hand during a time of fasting. It is good for the diseases of cows, but the one who gathers it must not look back nor place it anywhere except in the watering trough of the animals.
There is a kind of egg which is very famous in Gaul but ignored by Greek writers. In the summer months, a vast number of snakes will gather themselves together in a ball which is held together by their saliva and a secretion from their bodies. The Druids say they produce this egg-like object called an anguinum which the hissing snakes throw up into the air. It must be caught, so they say, in a cloak before it hits the ground. But you'd better have a horse handy, because the snakes will chase you until they are cut off by some stream. A genuine anguinum will float upstream, even if covered in gold. But as is common with the world's holy men, the Druids say it can only be gathered during a particular phase of the moon, as if people could make the moon and serpents work together. I saw one of these eggs myself-it was a small round thing like an apple with a hard surface full of indentations as on the arms of an octopus. The Druids value them highly. They say it is a great help in lawsuits and will help you gain the good will of a ruler. That this is plainly false is shown by a man of the Gaulish Vocontii tribe, a Roman knight, who kept one hidden in his cloak during a trial before the emperor Claudius and was executed, as far as I can tell, for this reason alone.
Barbarous rites were found in Gaul even within my own memory. For it was then that the emperor Tiberius passed a decree through the senate outlawing their Druids and these types of diviners and physicians. But why do I mention this about a practice which has crossed the sea and reached the ends of the earth? For even today Britain performs rites with such ceremony that you would think they were the source for the extravagant Persians. It is amazing how distant people are so similar in such practices. But at least we can be glad that the Romans have wiped out the murderous cult of the Druids, who thought human sacrifice and ritual cannibalism were the greatest kind of piety.
