Black Bile is An original piece of music I wrote this evening.
Melancholia or melancholy (from Greek: µέλαινα χολή melaina chole, meaning black bile) is a concept found throughout ancient, medieval and premodern medicine in Europe that describes a condition characterized by markedly depressed mood, bodily complaints, and sometimes hallucinations and delusions.
Melancholy was regarded as one of the four temperaments matching the four humors. Until the 18th century, doctors and other scholars classified melancholic conditions as such by their perceived common cause – an excess of a notional fluid known as "black bile", which was commonly linked to the spleen.
Between the late 18th and late 19th centuries, melancholia was a common medical diagnosis, and modern concepts of depression as a mood disorder eventually arose from this historical context.
Related concepts in historical medicine include: lugubriousness, from Latin lugere, "to mourn"; moroseness, from Latin morosus, "self-will or fastidious habit"; wistfulness, from obsolete English whist; and saturnineness, from Latin Sāturnīnus, "under the influence of the planet Saturn")
