Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840], at sacred-texts.com
To denote darkness, they represent the TAIL OF A CROCODILE, for by no other means does the crocodile inflict death and destruction on any animal which it may have caught, than by first striking it with its tail, and rendering it incapable of motion: for in this part lies the strength and power of the crocodile. And now, though there are other
appropriate symbols deducible from the nature of the crocodile, those which we have mentioned are sufficient for the first Book.
Τέλος τοῦ πρώτου βιβλίου.
END OF THE FIRST BOOK.
II. The fig. beneath certainly signifies darkness; and is supposed to represent the end of a crocodile's tail.
