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 it is 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. M. Gavius Apicius apparently owed his cognomen (his third name) to an earlier Apicius, who lived around 90 BC, whose family name it may have been: if this is true, Apicius had come to mean "gourmand" as a result of the fame of this earlier lover of luxury.
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. From these sources the following anecdotes about M. Gavius Apicius (hereafter called Apicius) survive: to what extent they form a real biography is doubtful.
Several recipes were named after Apicius, and probably M. Gavius Apicius is the person intended:
Throughout Roman literature Apicius is named in moralizing contexts as the typical gourmet or glutton. Seneca, for example, says that he "proclaimed the science of the cookshop" and corrupted the age with his example (Seneca, Consolatio ad Helviam 10). Around the 4th and 5th centuries, Apicius begins to be named as an author: this may be an indication that cookbooks titled Apicius were in circulation by that time. The first such reference may be that in the Scholia on Juvenal (4.22), which assert that Apicius wrote about how to arrange dinners, and about sauces.
