<P> Ancient Greek medicine was a compilation of theories and practices that were constantly expanding through new ideologies and trials . Many components were considered in ancient Greek medicine, intertwining the spiritual with the physical . Specifically, the ancient Greeks believed health was affected by the humors, gender, geographic location, social class, diet, trauma, beliefs, and mindset . Early on in the ancient Romans ancient Greeks believed that illnesses were "divine punishments" and that healing was a "gift from the Gods". As trials continued wherein theories were tested against symptoms and results, the pure spiritual beliefs regarding "punishments" and "gifts" were replaced with a foundation based in the physical, i.e., cause and effect . </P> <P> Humorism (or the four humors) refers to blood, yellow bile, black bile and phlegm . It was also theorized that gender played a role in medicine because some diseases and treatments were different for women than for men . Moreover, geographic location and social class affected the living conditions of the people and might subject them to different environmental issues such as mosquitoes, rats, and availability of clean drinking water . Diet was thought to be an issue as well and might be affected by a lack of access to adequate nourishment . Trauma, such as that suffered by gladiators, from dog bites or other injuries, played a role in theories relating to understanding anatomy and infections . Additionally, there was significant focus on the beliefs and mind set of the patient in the diagnosis and treatment theories . It was recognized that the mind played a role in healing, or that it might also be the sole basis for the illness . </P>
