of junior servants, but today a butler is more likely to wear a business suit or business casual clothing and appear in uniform only on special occasions. A silverman or silver butler has expertise and professional knowledge of the management, secure storage, use and cleaning of all silverware, associated tableware and other paraphernalia for use at military and other special functions. Origin and history The modern role of the butler has evolved from earlier roles that were generally concerned with the care and serving of alcoholic beverages. Ancient through medieval eras From ancient through medieval times, alcoholic beverages were chiefly stored first in earthenware vessels, then later in wooden barrels, rather than in glass bottles; these containers would have been an important part of a household's possessions. The care of these assets was therefore generally reserved for trusted slaves, although the job could also go to free persons because of heredity-based class lines or the inheritance of trades. The biblical book of Genesis contains a reference to a role precursive to modern butlers. The early Hebrew Joseph interpreted a dream of Pharaoh's שקה (shaqah) (literally "to give to drink"), which is most often translated into English as "chief butler" or "chief cup-bearer." In ancient Greece and Rome, it was nearly always slaves who were charged with the care and service of wine, while during the Medieval Era the pincerna filled the role within the noble court. The English word "butler" itself comes from the Middle English word bo(u)teler (and several other forms), from Anglo-Norman buteler, itself from Old Norman butelier, corresponding to Old French botellier ("bottle bearer"), Modern French bouteiller, and before that from Medieval Latin butticula. The modern English "butler" thus relates both to bottles and casks. Eventually the European butler emerged as a middle-ranking member of the servants of a great house, in charge of the buttery (originally a storeroom for "butts" of liquor, although the term later came to mean a general storeroom or pantry). While this is so for household butlers, those with the same title but in service to the Crown enjoyed a position of administrative power and were only minimally involved with various stores. Elizabethan through Victorian eras The Steward of the Elizabethan era was more akin to the butler that later emerged. Gradually, throughout the 19th century and particularly the Victorian era, as the number of butlers and other domestic servants greatly increased
