24 Equally well-known is the disease which they name sometimes the rainbow-hued, sometimes the royal. Of this Hippocrates said that if it comes on after the patient has been suffering from fever for seven days, the patient is safe, provided that the parts under the ribs remain soft. Diocles stated positively that if it arise after a fever, it is even favourable, but deadly if fever follows it. The colour reveals this malady, particularly of the eyes; they become yellow in the parts which should be white. And it is usually accompanied by thirst and headache and frequent hiccough and induration under the ribs on the right side, and when a sharp movement of the body is made there is difficulty in breathing and laxness of the limbs; and when the disease persists for a long while, the whole body whitens with a sort of pallor.
