Plutarch, De Iside et Osiride 75 (part 1)

οὐ μὴν οὐδʼ ὁ κροκόδειλος αἰτίας πιθανῆς ἀμοιροῦσαν ἔσχηκε τιμήν, ἀλλὰ μίμημα θεοῦ λέγεται γεγονέναι, μόνος μὲν ἄγλωσσος ὤν. φωνῆς γὰρ ὁ θεῖος λόγος ἀπροσδεής ἐστι, καί διʼ ἀψόφου βαίνων κελεύθου κατὰ δίκην τὰ θνήτʼ ἄγει μόνου δέ φασιν ἐν ὑγρῷ διαιτωμένου τὰς ὄψεις ὑμένα λεῖον καὶ διαφανῆ παρακαλύπτειν ἐκ τοῦ μετώπου κατερχόμενον, ὥστε βλέπειν μὴ βλεπόμενον, ὃ τῷ πρώτῳ θεῷ συμβέβηκεν. ὅπου δʼ ἂν ἡ θήλεια τῆς χώρας ἀποτέκῃ, τοῦτο Νείλου πέρας ἐπίσταται τῆς αὐξήσεως γενόμενον. ἐν ὑγρῷ γὰρ οὐ δυνάμεναι, πόρρω δὲ φοβούμεναι, τίκτειν, οὕτως ἀκριβῶς προαισθάνονται τὸ μέλλον, ὥστε τῷ ποταμῷ προσελθόντι χρῆσθαι λοχευόμεναι καὶ θάλπουσαι, τὰ δʼ ᾠὰ ξηρὰ καὶ ἄβρεκτα φυλάσσειν. ἑξήκοντα δὲ τίκτουσιν, καὶ τοσαύταις ἡμέραις ἐκλέπουσι, καὶ τοσούτους ζῶσιν ἐνιαυτοὺς οἱ μακρότατον ζῶντες, ὃ τῶν μέτρων πρῶτόν ἐστι τοῖς περὶ τὰ οὐράνια πραγματευομένοις ἀλλὰ μὴν τῶν διʼ ἀμφότερα τιμωμένων περὶ μὲν τοῦ κυνὸς εἴρηται πρόσθεν· ἡ δʼ ἶβις ἀποκτείνουσα μὲν τὰ θανατηφόρα τῶν ἑρπετῶν ἐδίδαξε πρώτη κενώματος ἰατρικοῦ χρείαν κατιδόντας οὕτω κλυζομένην καὶ καθαιρομένην ὑφʼ ἑαυτῆς· οἱ δὲ νομιμώτατοι τῶν ἱερέων καθάρσιον ὕδωρ ἁγνιζόμενοι λαμβάνουσιν ὅθεν ἶβις πέπωκεν· οὐ πίνει γὰρ ἢ νοσῶδες ἢ πεφαρμαγμένον οὐδὲ πρόσεισι. τῇ δὲ τῶν ποδῶν διαστάσει πρὸς ἀλλήλους καὶ τὸ ῥύγχος ἰσόπλευρον ποιεῖ τρίγωνον· ἔτι δʼ ἡ τῶν μελάνων πτερῶν πρὸς τὰ λευκὰ ποικιλία καὶ μῖξις ἐμφαίνει σελήνην ἀμφίκυρτον.

The crocodile, certainly, has acquired honour which is not devoid of a plausible reason, but he is declared to be a living representation of God, since he is the only creature without a tongue; for the Divine Word has no need of a voice, and through noiseless ways advancing, guides By Justice all affairs of mortal men. They say that the crocodile is the only animal living in the water which has a thin and transparent membrane extending down from his forehead to cover up his eyes, so that he can see without being seen; and this prerogative belongs also unto the First God. In whatever part of the land the female crocodile lays her eggs, well she knows that this is destined to mark the limit of the rise of the Nile; for the females, being unable to lay their eggs in the water and afraid to lay them far from it, have such an accurate perception of the future that they make use of the oncoming river as a guide in laying their eggs and in keeping them warm; and thus they preserve them dry and untouched by the water. They lay sixty eggs and hatch them in the same number of days, and those crocodiles that live longest live that number of years: the number sixty is the first of measures for such persons as concern themselves with the heavenly bodies. Of the animals that are held in honour for both reasons, mention has already been made of the dog. The ibis, which kills the deadly creeping things, was the first to teach men the use of medicinal purgations when they observed her employing clysters and being purged by herself. The most strict of the priests take their lustral water …
