Histories

The Arabians get frankincense in the foregoing way, and casia in the following way: when they go after it they bind oxhides and other skins all over their bodies and faces except for the eyes. Casia grows in a shallow lake; around this and in it live winged creatures, very like bats, that squeak similarly and make a fierce resistance; these have to be kept away from the eyes in order to take the casia.
