In existographies, Bion (325-250BC) (FA:26), aka “Bion of Borysthenes”, was a Greek philosopher

In 230AD, Diogenes Laertius, in his Lives of Eminent Philosophers (Ѻ), said the following on Bion and his atheism:

“Next he went over to Theodorean views, after he had heard the lectures of Theodorus the atheist, who used every kind of sophistical argument. And after Theodorus he attended the lectures of Theophrastus the Peripatetic. He was fond of display and great at cutting up anything with a jest, using vulgar names for things. Because he employed every style of speech in combination, Eratosthenes, we hear, said of him that he was the first to deck philosophy with bright-flowered robes. He was clever also at parody. Here is a specimen of his style:

O gentle Archytas, musician-born, blessed in thine own conceit, most skilled of men to stir the bass of strife.

And in general he made sport of music and geometry. He lived extravagantly, and for this reason he would move from one city to another, sometimes contriving to make a great show. Thus, at Rhodes he persuaded the sailors to put on students' garb and follow in his train. And when, attended by them, he made his way into the gymnasium, all eyes were fixed on him. It was his custom also to adopt certain young men for the gratification of his appetite and in order that he might be protected by their goodwill. He was extremely selfish and insisted strongly on the maxim that "friends share in common." And hence it came about that he is not credited with a single disciple, out of all the crowds who attended his lectures. And yet there were some who followed his lead in shamelessness. For instance, Betion, one of his intimates, is said once to have addressed Menedemus in these words: "For my part, Menedemus, I pass the night with Bion, and I don't think I am any the worse for it." In his familiar talk he would often vehemently assail belief in the gods, a taste which he had derived from Theodorus. Afterwards, when he fell ill (so it was said by the people of Chalcis where he died), he was persuaded to wear an amulet and to repent of his offences against religion. And even for want of nurses he was in a sad plight, until Antigonus sent him two servants. And it is stated by Favorinus in his Miscellaneous History that the king himself followed in a litter.

Even so he died, and in these lines I have taken him to task:

We hear that Bion, to whom the Scythian land of Borysthenes gave birth, denied that the gods really exist. Had he persisted in holding this opinion, it would have been right to say, "He thinks as he pleases: wrongly, to be sure, but still he does think so." But in fact, when he fell ill of a lingering disease and feared death, he who denied the existence of the gods, and would not even look at a temple, who often mocked at mortals for sacrificing to deities, not only over hearth and high altars and table, with sweet savour and fat and incense did he gladden the nostrils of the gods; nor was he content to say "I have sinned, forgive the past," but he cheerfully allowed an old woman to put a charm round his neck, and in full faith bound his arms with leather and placed the rhamnus and the laurel-branch over the door, being ready to submit to anything sooner than die. Fool for wishing that the divine favor might be purchased at a certain price, as if the gods existed just when Bion chose to recognize them! It was then with vain wisdom that, when the driveller was all ashes, he stretched out his hand and said "Hail, Pluto, hail!"”

Bion, in short, was considered an atheist, was a follower of the atheistic ideas of Theodorus and Theophrastus, was said to have “stated main things against the gods”, and lectured following the example of Theodorus. [2]
