It has long been known that the Egyptian pharaoh was regarded as divine in Egyptian culture. He was the son of Re and the mediator between the gods and humankind. During the royal coronation, he was transformed into a manifestation of the god Horus. He could be referred to as a ntr (‘divine being’, ‘god’), and was regularly described in inscriptions as ‘the good god’ or ‘perfect god’ (ntr nfr).Footnote 1 By the New Kingdom period, the king's divinity was believed to be imbued by his possession of a divine manifestation of the god Amun-Re called the ‘living royal ka’, which came upon him at his coronation, and which was also renewed during the yearly opet festival held in the Luxor temple in Thebes.Footnote 2 As late as the period of Persian domination over Egypt in the fifth century b.c., Egyptian temple texts continued to describe their foreign king Darius I as a divine being, owing to the ‘living royal ka’.Footnote 3 This hieroglyphic formula proclaiming the king's divinity continues for Alexander the Great and even in Ptolemaic temple reliefs.Footnote 4
In light of this, it is surprising that the idea of the pharaoh's divinity is virtually unknown in surviving Classical Greek and Hellenistic sources, except perhaps for some Ptolemaic poetry (e.g. Callim. Hymn 4.165) where the divinity of the king could just as easily be a Greek cultural idea rather than an Egyptian one. Herodotus' Histories display no knowledge of the ‘god king’ of Egypt. Herodotus declares that the Egyptian priests said that no god had assumed human form in the 341 generations since Egypt's first pharaoh – a statement which some think contradicts the idea of the divine status of the king.Footnote 5 The only explicit statement in a Greek source about the Egyptian king's divinity can be seen in Diodorus Siculus, writing as late as the first century b.c., and relying most probably on Hecataeus of Abdera:
καθόλου δέ ϕασι τοὺς Αἰγυπτίους ὑπὲρ τοὺς ἄλλους ἀνθρώπους εὐχαρίστως διακεῖσθαι πρὸς πᾶν τὸ εὐεργετοῦν, νομίζοντας μεγίστην ἐπικουρίαν εἶναι τῷ βίῷ τὴν ἀμοιβὴν τῆς πρὸς τοὺς εὐεργέτας χάριτος· δῆλον γὰρ εἶναι διότι πάντες πρὸς εὐεργεσίαν ὁρμήσουσι τούτων μάλιστα παρ᾽ οἷς ἂν ὁρῶσι κάλλιστα θησαυρισθησομένας τὰς χάριτας. διὰ δὲ τὰς αὐτὰς αἰτίας δοκοῦσιν Αἰγύπτιοι τοὺς ἑαυτῶν βασιλεῖς προσκυνεῖν τε καὶ τιμᾶν ὡς πρὸς ἀλήθειαν ὄντας θεούς, ἅμα μὲν οὐκ ἄνευ δαιμονίου τινὸς προνοίας νομίζοντες αὐτοὺς τετευχέναι τῆς τῶν ὅλων ἐξουσίας, ἅμα δὲ τοὺς βουλομένους τε καὶ δυναμένους τὰ μέγιστ᾿ εὐεργετεῖν ἡγούμενοι θείας μετέχειν ϕύσεως.
In general, they say that the Egyptians above all other people are inclined to be grateful for every benefaction, believing that the return of gratitude to benefactors is a great resource in life. For, they say, it is clear that all human beings will want to grant their benefactions mainly to those who they know will value the favours best. For the same reasons, it seems, the Egyptians practise proskynesis before their kings and honour them as being in truth gods, believing that they have not attained supreme power without the help of divine providence, and also that those who are willing to give the greatest benefactions and have the power to give such honours share in the divine nature.Footnote 6
(Diod. Sic. 1.90.2–3 = Hecataeus of Abdera, FGrH 264 F 25.1488–97)This passage of Diodorus was assigned by Jacoby to Hecataeus of Abdera's On the Egyptians (Aegyptiaca), which appears to be a major source for Book 1 of Diodorus' universal history.Footnote 7 Hecataeus wrote his work in Egypt under Ptolemy I and claimed knowledge of priestly records and informants.Footnote 8 The work should be dated to the years between 321 and 304 b.c., but probably in the earlier part of this period.Footnote 9 It seems clear that Diodorus did draw on Hecataeus for much of his material,Footnote 10 although the extent to which he used Hecataeus in Book 1 has been disputed, and he did use other sources.Footnote 11 But it is notable that the motive for the worship of kings in Diodorus fits very well with the euhemerism of Hecataeus,Footnote 12 Hecataeus' theory of kingship, and his overall method of interpreting Egyptian culture in a Hellenized way. Nevertheless, it can be conceded that there remains the possibility that 1.90.2–3 was an editorial comment of Diodorus himself or was derived from another Hellenistic source.
Curiously, what Diodorus has recorded here contradicts what he himself wrote elsewhere (most probably indicating the use of different sources), when he asserts that the piety of Darius and his interest in Egyptian religion led to his being the first king to be honoured as a god by the Egyptians.Footnote 13
There is another important observation to be made, whatever the ultimate source of Diodorus 1.90.2–3. The language of Diodorus (εὐεργέτας, εὐεργετεῖν) appears to be derived from Hellenistic ruler cult ideology, and the motive which he gives for divine honours is Hellenistic, not Egyptian. The ruler cults of the Hellenistic age were very frequently inspired by the gratitude of cities and individuals in response to benefactions made by kings.Footnote 14 It is doubtful how far Diodorus in this passage or his source evinced any understanding of the native Egyptian conception of the pharaoh's divinity. It is highly unlikely that the ancient Greeks understood the notion of the ka divinity of the king, an idea which was mainly expressed in temple propaganda. Nevertheless, the virtual absence of other earlier passages in Greek literature at least mentioning the divinity of the pharaoh in passing remains a puzzle.
A possible solution is that some sectors of Egyptian society and the priesthood may have adopted a more prosaic view of the king's nature by the Saite age,Footnote 15 although conservative temple hieroglyphic texts unreadable to Greeks did not abandon the divine ideology.Footnote 16 Thus there had arisen a popular ‘secular’ attitude to the kingship by the Late period in Egypt.Footnote 17 Some Egyptologists have even argued that late Egyptians had abandoned the idea that the pharaoh was divine.Footnote 18 Still others posit that there was a ‘schism’ in late Egyptian thought where older conservative ideas existed alongside more earthly conceptions of the kingship.Footnote 19 Under the last view, it is entirely possible that the Greeks of the Archaic and Classical eras and the fourth century b.c. were largely unaware of the native and conservative Egyptian conception of the pharaoh as a divine being, simply because that idea had retreated in late popular Egyptian culture. This is what explains the clear absence of passages in Greek literature before Diodorus concerning the divine Egyptian king. Whether or not Diodorus 1.90.2–3 in fact stems from Hecataeus of Abdera, by the Hellenistic age, through contact with Egypt, the Greeks were commenting on the older, conservative Egyptian belief in the divine pharaoh, but saw the idea through the prism of Greek culture and Hellenistic ruler cults, which also envisaged the ruler as divine, but for quite different reasons.
