Anger is the ebullition ζέσις, boiling. of the heart’s blood τοῦ περὶ καρδίαν αἵματος, the blood about the heart. produced by bilious exhalation or turbidity. Hence it is that the words χολή and χόλος Nemes., ch. 21. are both used in the sense of anger. Anger is sometimes lust for vengeance. For when we are wronged or think that we are wronged, we are distressed, and there arises this mixture of desire and anger.
