Quote[11] [However, Zeno had good reason to ?] consider, in connection with many [writings of our school], that a doubt hung over the opinions which were those of our great men at the origins [of the Garden]; thus [he designated for Epicurus] certain letters, the summary on celestial phenomena To Pythocles ([Πρὸς Πυ]θ̣οκλέα περὶ̣ μ̣[ε]τεώρων ἐπιτομῆςand)
...I had no idea that there was even a suggestion that the authorship of the Letter to Pythocles was in dispute in the late second and early first centuries BC; that actually blows my mind. The Greek text at the Perseus Project has this at the beginning of the letter;
Ἐπίκουρος Πυθοκλεῖ χαίρειν.
"Epicurus to Pythocles, greeting."
There's a lot to unpack here.
