deipnosophist (n.)

"gourmand," 1650s, from Greek deipnosophistes "one learned in the mysteries of the kitchen," from deipnon "chief meal, dinner" (which is of unknown origin) + sophistes "master of a craft" (see sophist). the word has come down thanks to "Deipnosophistai," 2c. B.C.E. work on gastronomy by Athenaeus.
