Classical masterpiece "The Origin series" chef d'œuvre (French, master of work,) in modern use refers to a creation that has been given much critical praise, especially one that is considered the greatest work of a person's career or to a work of outstanding creativity, skill, profundity, or workmanship. Historically, the word refers to a work of a very high standard produced in order to obtain membership of a Guild or Academy. a piece of work produced by an apprentice or journeyman aspiring to become a master craftsman in the old European guild system. His fitness to qualify for guild membership was judged partly by the masterpiece, and if he was successful, the piece was retained by the guild. Great care was therefore taken to produce a fine piece in whatever the craft was, whether confectionery, painting, goldsmithing, knifemaking, and Mixology trades in the 17th century.
