Strabo 7.6.2
The Horn, which is close to the wall of the Byzantines, is a gulf that extends approximately towards the west for a distance of sixty stadia; it resembles a stag's horn, for it is split into numerous gulfs--branches, as it were. The pelamydes rush into these gulfs and are easily caught--because of their numbers, the force of the current that drives them together, and the narrowness of the gulfs; in fact, because of the narrowness of the area, they are even caught by hand.
