Maybe It Was For the Best that Alexander Died (Arrian, History of Alexander 7.16.8)

“Perhaps it was also a better fate for him to die at the height of his reputation and when he would be missed by men before he could suffer that common human fate, which is the very thing Solon warned Kroisos about: that it is best to look to the end of even a long life and never to say openly that some man is fortunate before he is dead.”

καί που τυχὸν καὶ ἄμεινον αὐτῷ ἦν ἐν ἀκμῇ τῆς τε ἄλλης δόξης καὶ τοῦ πόθου τοῦ παρ’ ἀνθρώπων ἀπηλλάχθαι, πρίν τινα ξυμβῆναι αὐτῷ ξυμφορὰν ἀνθρωπίνην, ἧς ἕνεκα καὶ Σόλωνα Κροίσῳ παραινέσαι εἰκὸς τέλος ὁρᾶν μακροῦ βίου μηδὲ πρόσθεν τινὰ ἀνθρώπων ἀποφαίνειν εὐδαίμονα.
