Regarding the gods, the most learned Diodorus also says in his writings that those gods whom men were wont to address as immortal, considering them to be so because of their beneficences, had indeed been born human beings; but that certain of them had acquired the appellations they have after the lands they conquered.
Diodorus says, following the account preserved in the myths, that Xanthus and Balius were formerly Titans and had come to the aid of Zeus, Xanthus as a companion of Poseidon and Balius of Zeus; and in the battle they asked that their shape might be changed, since they were ashamed to be seen by their brethren the Titans, and their request was granted; and it was these horses which were given to Peleus. This explains, Diodorus says, why Xanthus is able to prophesy his death to Achilleus.
Pherecydes records that Saturnus was the first, before all others, to wear a crown, and Diodorus relates that, after he had defeated the Titans, Jupiter was rewarded by the rest with this same distinction; the same writer gives even to Priapus fillets and to Ariadnê a wreath made of gold and precious stones from India, this wreath becoming also a distinction of Vulcan, and then of Liber, and later a constellation.
Ninus’ brother, Picus, who was also called Zeus, but also king of Italy, holding sway over the west for one hundred and twenty years. And he had many sons and daughters by the most comely women; for he assumed in some cases mysterious aspects when seducing them. And these women, when they were being debauched by him, looked upon him as a god. This same Picus, who was also called Zeus, had a son named Faunus, whom he also called Hermes for the name of the wandering star. And when Zeus was on the point of death he gave orders that his remains be laid away on the island of Crete; and his sons built him a temple there in which they laid him. This monument exists even to the present day, and it bears the inscription “Here lies Picus whom men also call Zeus.” Diodorus, the most learned chronographer, has composed an account of this Picus.
According to tradition, Castor and Polydeuces, who were also known as the Dioscori, far surpassed all other men in valour and gained the greatest distinction in the campaign in which they took part with the Argonauts; and they have come to the aid of many who have stood in need of succour. And, speaking generally, their manly spirit and skill as generals, and their justice and piety as well, have won them fame among practically all men, since they make their appearance as helpers of those who fall into unexpected perils. Moreover, because of their exceptional valour they have been judged to be sons of Zeus, and when they departed from among mankind they attained to immortal honours.
Epopeus, the king of Sicyon, challenged the gods to battle and violated their sanctuaries and altars.
Sisyphus, we are told, excelled all other men in knavery and ingenuity, and by means of his skill in divination by inspection of victims he discovered everything that was to happen and foretold it to mankind.
Salmoneus was impious and arrogant and made it his practice to ridicule the divinity, and he declared that his achievements excelled those of Zeus. Consequently he used to make a tremendous noise by means of a machine he contrived and to imitate in this way peals of thunder, and he would celebrate neither sacrifices nor festivals.
The same Salmoneus had a daughter named Tyro, who received this name by reason of the whiteness and softness of her body.
For Salmoneus, being impious and arrogant, made it his practice to ridicule the divinity and to declare that his achievements excelled those of Zeus; consequently he used to make a tremendous noise by means of a machine he contrived, and by imitating claps of thunder he would declare that he had thundered more loudly than Zeus. Speaking generally, in his mockery of the gods he would celebrate neither sacrifices nor festivals in their honour, as the other rulers were accustomed to do. And there was born to him an only daughter, Tyro, to whom he thought this name was appropriate by reason of the softness of her body and the whiteness of her skin. Poseidon became enamoured of this maiden because of her beauty, and lying with her he begat Pelias and Neleus. And Salmoneus, not believing that it was Poseidon who had taken her virginity, would not leave off ill-treating Tyro; but in the end he paid the penalty to the deity for his impiety, ending his life when struck by lightning from the hand of Zeus. Of the sons born of Poseidon and Tyro, Pelias, when very young, was banished from his native land by Mimas, and going into exile together with his friends, he seized, with their aid, two islands, Sciathos and Peparethos; but at a later time, since Cheiron conferred benefactions upon him and shared his own country with him he departed from the islands we have mentioned, and became king of the city of Iolci. And there were born to him a number of daughters who took their name from their father, being called the Peliades, regarding whom we shall rest content with what has been said.
Admetus was very dear to the gods because of his unusual righteousness and piety. His uprightness brought him such honour that once, when Apollo had offended Zeus, the command was given him that he should serve as a menial at the court of Admetus. And we are told that Alcestis, the daughter of Pelias, who was the only one of his daughters who had no part in the impiety practised upon their father, was given as a wife to Admetus because of her piety.
Melampus was a man of exceptional piety and became a friend of Apollo.
Bellerophon, who was in exile because of a murder he had unwittingly committed, came to Proetus who exchanged hospitality with his father; and the wife of Proetus became enamoured of Bellerophon because of his beauty, and since she was unable to win him by persuasion she accused him to her husband of having offered violence to her. Now Proetus was unwilling to slay his guest, and so instead he sent him to Lycia, having a written message to Iobates the king, who was his father-in-law. Iobates received the letter and discovered that in it was written that he should slay Bellerophon with all speed; but, being unwilling to put him to death, he commanded him instead to go join combat with the fire-breathing Chimaera.
