The repute of Melampus, as being highly skilled in the arts of divination, is universally known. This personage has given a name to one species of hellebore, known as the “melampodion.” Some persons, however, attribute the discovery of this plant to a shepherd of that name, who remarked that his she-goats were violently purged after browsing upon it, and afterwards cured the daughters of Prœtus of madness, by giving them the milk of these goats. It will be the best plan, therefore, to take this opportunity of treating of the several varieties of hellebore. The two principal kinds are the white[606] and the black;[607] though, according to most authorities, this difference exists in the root only. There are some authors, however, who assure us that the leaves of the black hellebore are similar to those of the plane-tree, only darker, more diminutive, and more jagged at the edges: and who say, that the white hellebore has leaves like those of beet when first shooting, though at the same time of a more swarthy colour, with reddish veins on the under side. The stem, in both kinds, is ferulaceous, a palm[608] in height, and covered with coats like those of the bulbs, the root, too, being fibrous like that of the onion.[609] The black hellebore kills horses, oxen, and swine; hence it is that those animals avoid it, while they eat the white[610] kind. The proper time, they say, for gathering this last, is harvest. It grows upon Mount Œta in great abundance; and the best of all is that found upon one spot on that mountain, in the vicinity of Pyra. The black hellebore is found growing everywhere, but the best is that of Mount Helicon; which is also equally celebrated for the qualities of its other plants. The white hellebore of Mount Œta is the most highly esteemed, that of Pontus occupying the second place, and the produce of Elea the third; which last, it is generally said, grows in the vineyards there. The fourth rank is held by the white hellebore of Mount Parnassus, though it is often, adulterated with that of the neighbouring districts of Ætolia.
