The Latin text of this clause is, “Quia autem triginta annorum ætas prima indolis est juvenis”—words which it seems almost impossible to translate. Grabe regarded “indolis” as being in the nominative, while Massuet contends it is in the genitive case; and so regarding it, we might translate, “Now that the age of thirty is the first age of the mind of youth,” etc. But Harvey re-translates the clause into Greek as follows: Ὃτι δὲ ἡ τῶν τριάκοντα ἐτῶν ἡλικία ἡ πρώτη τῆς διαθέσεώς ἐστι νέας—words which we have endeavoured to render as above. The meaning clearly is, that the age of thirty marked the transition point from youth to maturity.
