or houses, where even to break a twig would have been a sin. They thought that he who cut a bough in such a grove either died suddenly or was crippled in one of his limbs. Proofs of the prevalence of tree-worship in ancient Greece and Italy are abundant. In the sanctuary of Aesculapius at Cos, for example, it was forbidden to cut down the cypress-trees under a penalty of a thousand drachms. But nowhere, perhaps, in the ancient world was this antique form of religion better preserved than in the heart of the great metropolis itself. In the Forum, the busy centre of Roman life, the sacred fig-tree of Romulus was worshipped down to the days of the empire, and the withering of its trunk was enough to spread consternation through the city. Again, on the slope of the Palatine Hill grew a cornel-tree which was esteemed one of the most sacred objects in Rome. Whenever the tree appeared to a passer-by to be drooping, he set up a hue and cry which was echoed by the people in the street, and soon a crowd might be seen running helter-skelter from all sides with buckets of water, as if (says Plutarch) they were hastening to put out a fire.
Among the tribes of the Finnish-Ugrian stock in Europe the heathen worship was performed for the most part in sacred groves, which were always enclosed with a fence. Such a grove often consisted merely of a glade or clearing with a few trees dotted about, upon which in former times the skins of the sacrificial victims were hung. The central point of the grove, at least among the tribes of the Volga, was the sacred tree, beside which everything else sank into insignificance. Before it the worshippers assembled and the priest offered his prayers, at its roots the victim was sacrificed, and its boughs sometimes served as a pulpit. No wood might be hewn and no branch broken in the grove, and women were generally forbidden to enter it.
But it is necessary to examine in some detail the notions on which the worship of trees and plants is based. To the savage the world in general is animate, and trees and plants are no exception to the rule. He thinks that they have souls like his own, and he treats them accordingly. "They say," writes the ancient vegetarian Porphyry, "that primitive men led an unhappy life, for their superstition did not stop at animals but extended even to plants. For why should the slaughter of an ox or a sheep be a greater wrong than the felling of a fir or an oak, seeing that a soul is implanted in these trees also?" Similarly, the Hidatsa Indians of North America believe that every natural object has its spirit, or to speak more properly, its shade. To these shades some consideration or respect is due, but not equally to all. For example, the shade of the cottonwood, the greatest tree in the valley of the Upper Missouri, is supposed to possess an intelligence which, if properly approached, may help the Indians in certain undertakings; but the shades of shrubs and grasses are of little account. When the Missouri, swollen by a freshet in spring, carries away part of its banks and sweeps some tall tree into its current, it is said that the spirit of the tree cries, while the roots still cling to the land and until the trunk falls with a splash into the stream.
