Aelian, History of Animals Prologue
“How much toil others have contributed on these topics, I know well. But after I collected as many sources as possible and communicated them in understandable language, I am convinced that I have made a contribution with is not unworthy of this toil. So, if they seem useful to anyone, may they enjoy them.
To anyone to whom they may seem unprofitable, well, give them to your father to keep warm and work over. For all things are not fine to all people, nor do they seem worthy of enthusiasm to all people the same. Even though in this work I follow many wise authors before me, do not let the mere fact of time be a reason for depriving me of praise if I also have prepared something learned, worthy of praise thanks both to its deeper research and its language.”
ὡς μὲν οὖν καὶ ἑτέροις ὑπὲρ τούτων ἐσπούδασται, καλῶς οἶδα · ἐγὼ δὲ [ἐμαυτῷ] ταῦτα ὅσα οἷόν τε ἦν ἀθροίσας καὶ περιβαλὼν αὐτοῖς τὴν συνήθη λέξιν, κειμήλιον οὐκ ἀσπούδαστον ἐκπονῆσαι πεπίστευκα. εἰ δέ τῳ καὶ ἄλλῳ φανεῖται ταῦτα λυσιτελῆ, χρήσθω αὐτοῖς· ὅτῳ δὲ οὐ φανεῖται, ἐάτω τῷ πατρὶ θάλπειν τε καὶ περιέπειν · οὐ γὰρ πάντα πᾶσι καλά, οὐδὲ ἄξια δοκεῖ σπουδάσαι πᾶσι πάντα. εἰ δὲ ἐπὶ πολλοῖς τοῖς πρώτοις καὶ σοφοῖς γεγόναμεν, μὴ ἔστω ζημίωμα ἐς ἔπαινον ἡ τοῦ χρόνου λῆξις, εἴ τι καὶ αὐτοὶ σπουδῆς ἄξιον μάθημα παρεχοίμεθα καὶ τῇ εὑρέσει τῇ περιττοτέρᾳ καὶ τῇ φωνῇ.
