Edfu and Denderah may almost be called twin temples. They belong to the same period. They are built very nearly after the same plan.[183] They are even allied in a religious sense; for the myths of Horus[184] and Hathor[185] are interdependent; the one being the complement of the other. Thus, in the inscriptions of Edfu we find perpetual allusion to the cultus of Denderah, and vice versa. Both Edfu and Denderah are rich in inscriptions; but as the extent of wall-space is greater at Edfu, so is the literary wealth of this temple greater than the literary wealth of Denderah. It also seemed to me that the surface was more closely filled in at Edfu than at Denderah. Every wall, every ceiling, every pillar, every architrave, every passage and side-chamber, however dark, every staircase, every doorway, the outer wall of the temple, the inner side of the great wall of circuit, the huge pylons from top to bottom, are not only covered, but crowded, with figures and hieroglyphs. Among these we find no enormous battle-subjects as at Abou Simbel--no heroic recitals, like the poem of Pentaur. Those went out with the Pharaohs and were succeeded by tableaux of religious rites and dialogues of gods and kings. Such are the stock subjects of Ptolemaic edifices. They abound at Denderah and Esneh, as well as at Edfu. But at Edfu there are more inscriptions of a miscellaneous character than in any temple of Egypt; and it is precisely this secular information which is so priceless. Here are geographical lists of Nubian and Egyptian gnomes, with their principal cities, their products and their tutelary gods; lists of tributary provinces and princes; lists of temples and of lands pertaining thereunto; lists of canals, of ports, of lakes; calendars of feasts and fasts; astronomical tables; genealogies and chronicles of the gods; lists of the priests and priestesses of both Edfu and Denderah, with their names; lists also of singers and assistant functionaries; lists of offerings, hymns, invocations; and such a profusion of religious legends as make of the walls of Edfu alone a complete text-book of Egyptian mythology.[186]
