I was tracing a Latin quote from Erasmus and it went a little deeper than expected, so I thought it best to share—
The quote from Erasmus: nōn semper erit aestās (Adagia, 4.3.86)
The immediate comparison to this in Latin would be Seneca’s dicēbam vōbīs: nōn semper erunt Satūrnālia (Apocolocyntosis, 12)
The general sense here is “winter is coming,” and therefore scholars have rightly traced these sentiments back to Hesiod, Work and Days 503:
“οὐκ αἰεὶ θέρος ἐσσεῖται—ποιεῖσθε καλīάς!”
The καλιά is a storage barn, though searching for καλιάς on Google I found this little gem: http://www.urbandictionary.com/define.php?term=kalias
