One of the physical phenomena attending our Lords agony in the garden of Gethsemane is described by St. Luke, ( Luke 22:44 ) "His sweat was as it were great drops (lit. clots) of blood falling down to the ground." Of this malady, known in medical science by the term diapedesis , there have been examples recorded in both ancient and modern times. The cause assigned is generally violent mental emotion.
