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.
