Marcus Gavius Apicius is believed to have been a Roman gourmet and lover of luxury, who lived sometime in the 1st century AD, during the reign of Tiberius. The Roman cookbook Apicius is often attributed to him, though its impossible to prove the connection. He was the subject of On the Luxury of Apicius, a famous work, now lost, by the Greek grammarian Apion.
Evidence for the life of M. Gavius Apicius derives partly from contemporary or almost-contemporary sources but is partly filtered through the above-named work by Apion, whose purpose was presumably to explain the names and origins of luxury foods, especially those anecdotally linked to Apicius.
