Homer, Iliad 5.837-9
“The goddess Athena climbed into the chariot next to godlike Diomedes in haste; the oak axle groaned greatly under the weight, for it carried both the terrible goddess and the noble man.”
ἣ δ᾽ ἐς δίφρον ἔβαινε παραὶ Διομήδεα δῖον
ἐμμεμαυῖα θεά: μέγα δ᾽ ἔβραχε φήγινος ἄξων
βριθοσύνῃ: δεινὴν γὰρ ἄγεν θεὸν ἄνδρά τ᾽ ἄριστον.
Vergil, Aeneid 6.412-13
“He accepted huge Aeneas into the hollow craft; the boat groaned under his weight.”
…simul accipit alveo
ingentem Aenean. gemuit sub pondere cumba
