From the article: 'In ancient and in medieval times, acorns were also occasionally employed as food for man, in cases of emergency: “when there is scarcity of corn”, Pliny noted in the Naturalis Historia'...
Does anyone know if this quote is correct, or how it might be better rendered? Isn't corn (maize) a new world food that Pliny would be unfamiliar of, let alone consider a staple?
