The name comes from the medieval-Latin term balneum (or balineum) Mariae—literally, Mary's bath—from which the French bain de Marie, or bain-marie, is derived. In his books, the 300 AD alchemist Zosimos of Panopolis credits for the invention of the device Mary the Jewess,[1] an ancient alchemist. #wikipedia_entry #cooking #chemistry #history #cool_facts #witchy #alchemy
