Pliny the Elder, a Roman historian born in 23 AD, wrote about Teran production in his work Naturalis Historia, consisting of 37 books. He mentions that the Karst red wine was not only known to Romans, but to Greeks as well, under the name of "praetorian wine of the Northern Adriatic".
Caesar Augustus' wife Julia attributed her high age of 82 to regular consumption of the so called pucinium which was produced on stone hills near the river Timavo spring. Valvasor, the famous Slovene polymath, describes the economic importance of the wine for the Karst region in his work The Glory of the Duchy of Carniola.
