[2891] 532 years, according to Hardouin. Bailly says: “The first men who studied the heavens remarked that the revolution of the sun brought back the seasons in the same order. They thought that they observed that certain variations of the temperature depended upon the aspect of the moon, and attached different prognostics to the rising and setting of the stars, persuading themselves that the vicissitudes of things here below had regulated periods, like the movements of the heavenly bodies. From this arose the impression, that the same aspect, the same arrangement of all the stars, that had prevailed at the commencement of the world, would also attend its destruction; and that the period of this long revolution was the predestined duration of the life of nature. Another impression was the idea that the world would only perish at this epoch to be born again, and for the same order of things to recommence with the same series of celestial phenomena. Some fixed this universal renovation at the conjunction of all the planets, others at the return of the stars to the same point of the ecliptic; others, uniting these two kinds of revolutions, marked the term of the duration of all things at the moment at which the planets and the stars would return to the same primitive situation with regard to the ecliptic, or in other words, they conceived an immense period, which would include one or more complete revolutions of each of the planets. All these periods were called the ‘great year,’ or the ‘great revolution.’” Histoire de l’Astronomie Ancienne.

[2894] A public place in the Forum, where the comitia curiata were held, and certain offences tried and punished.
[2895] Cuvier remarks, that this passage is borrowed, with some changes, from Aristotle’s “History of Animals,” B. ix. c. 32, but that the account given by Pliny is not very easily explained, from the fact that the word eagle is not used by him in a rigorous acceptation of the word. Indeed it is only at the present day that any accurate knowledge has been obtained as to the different species of eagles, and the changes of colour to which they are subject with the advance of age; circumstances which have caused the species of them to be multiplied by naturalists. It is very doubtful, he says, whether Aristotle has distinguished the various kinds any better than Pliny; although Buffon, who himself was not very successful in distinguishing them, says that Aristotle understood more on the subject than the moderns.
[2896] Μελανάετος, or the “black eagle.” Cuvier says, that this description is copied exactly from Aristotle, Hist. Anim. B. ix. c. 32. This eagle, he says, cannot be, as is commonly supposed, the “common eagle.” It can only be, he thinks, the “small” eagle, the female of which, according to Nauman and Savigny, when it is old is almost all black, and without spots; only the young being spotted.
[2897] From the Greek πυγὴ ἀργὴ, “white tail.” Cuvier remarks, that this is copied exactly from Aristotle, except that he says nothing about the whiteness of the tail, which is an interpolation. The feathers as described agree with those of the common eagle, the Falco fulvus, which is strong enough to seize a fawn. As regards its habit, he says, of dwelling on plains, that would agree better with the Jean le blanc of the French, the Falco Gallicus; while the name of pygargus is commonly applied, at the present day, to the great sea-eagle, the Falco albicilla; which frequents lakes and the sea-shore, and therefore corresponds more nearly with the haliætus of Pliny.
[2898] Cuvier says, that he is almost tempted to believe that it is the balbusard, the Falco haliætus, that is here meant, as it has a black back, and lives in the vicinity of lakes. But then, he remarks, it lives on fish and not aquatic birds; while, on the other hand, the little eagle of Buffon, the Falco nævio, often seizes ducks and other aquatic animals. He is inclined then, notwithstanding the apparent confusion, to take this morphnos for the modern small eagle. The words μορφνὸς and περκνὸς signify “black.”
[2899] From the Greek, meaning “black wing.”
[2900] “Mountain stork.” Buffon thinks that this is the great brown vulture; Cuvier, the great white-headed eagle.
