Some of the earliest descriptions of western bathing practices came from Greece. The Greeks began bathing regimens that formed the foundation for modern spa procedures. These Aegean people utilized small bathtubs, wash basins, and foot baths for personal cleanliness. The earliest such findings are the baths in the palace complex at Knossos, Crete, and the luxurious alabaster bathtubs excavated in Akrotiri, Santorini; both date from the mid-2nd millennium BC. They established public baths and showers within their gymnasium complexes for relaxation and personal hygiene. Greek mythology specified that certain natural springs or tidal pools were blessed by the gods to cure disease. Around these sacred pools, Greeks established bathing facilities for those desiring healing. Supplicants left offerings to the gods for healing at these sites and bathed themselves in hopes of a cure. The Spartans developed a primitive vapor bath. At Serangeum, an early Greek balneum (bathhouse, loosely translated), bathing chambers were cut into the hillside from which the hot springs issued. A series of niches cut into the rock above the chambers held bathers’ clothing. One of the bathing chambers had a decorative mosaic floor depicting a driver and chariot pulled by four horses, a woman followed by two dogs, and a dolphin below. Thus, the early Greeks used the natural features, but expanded them and added their own amenities, such as decorations and shelves. During later Greek civilization, bathhouses were often built in conjunction with athletic fields. Yet, the most developed and sophisticated use of water with healing and relaxation purposes comes from Turkish hammams, and Arab baths. This therapeutic use of water was introduced by Muslims in the European Middle Ages through Spain (al-Andalus). The biggest Arab baths in the world outside a Muslim country are those located in the Spanish city of Jaén, and date back to the 12th century.
