The honey is always best in those countries where it is to be found deposited in the calix of the most exquisite flowers, such, for instance, as the districts of Hymettus and Hybla, in Attica and Sicily respectively, and after them the island of Calydna.[1] At first, honey is thin, like water, after which it effervesces for some days, and purifies itself like must. On the twentieth day it begins to thicken, and soon after becomes covered with a thin membrane, which gradually increases through the scum which is thrown up by the heat. The honey of the very finest flavour, and the least tainted by the leaves of trees, is that gathered from the foliage of the oak and the linden, and from reeds.
