What is the origin of deipnosophist?

No dinner party is complete without a deipnosophist “a person who is an adept conversationalist at a meal.” This is the type of person who, at least as dictionary editors hope, regales fellow feasters with the origin of such an intriguing word as deipnosophist. Deipnosophist is based on Deipnosophistaí, the title of a literary work by Athenaeus, a Greek philosopher and rhetorician writing in Naucratis, Egypt, in the late 200s a.d. Deipnosophistaí is the plural of deipnosophistḗs, literally “an expert in the affairs of the kitchen,” and the work features a banquet where learned men discuss food and a wide range of other topics. Deipnosophistḗs is formed on Greek deîpnon “meal, dinner” and sophistḗs “expert, wise person.” Sophistḗs is the source of English sophist, which historically refers to a type of professional teacher in ancient Greece and later, a person who argues cleverly but speciously. Sophistḗs is related to Greek sophía “skill, wisdom,” source of the –sophy in philosophy. Deipnosophist is recorded in English by the 1600s.
