The substance called "antispodos"[1] is produced from the ashes of the fig-tree or wild fig, or of leaves of myrtle, together with the more tender shoots of the branches. The leaves, too, of the wild olive[2] furnish it, the cultivated olive, the quince-tree, and the lentisk; unripe mulberries also, before they have changed their colour, dried in the sun; and the foliage of the box, pseudo-cypirus,[3] bramble, terebinth and œnanthe.[4] The same virtues have also been found in the ashes of bull-glue[5] and of linen cloth. All these substances are burnt in a pot of raw earth, which is heated in a furnace, until the earthenware is thoroughly baked.
