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.
