Note 2736 — BOOK XXII. THE PROPERTIES OF PLANTS AND FRUITS.

Honied wine being considered so noble a beverage, Celsus says, that “during its cure, the patient must be kept to his chamber, and the mind must be kept cheerful, with gaiety and pastimes, for which reason it is called the ‘royal disease,’” B. iii. c. 24. In the text Pliny calls it “arquatorum morbus,” the “disease of the bow-like,” if we may be allowed the term. The origin of this term, according to Scribonius Largus, is the word “arcus,” the rainbow, from a fancied resemblance of the colour of the skin, when affected with jaundice, to the green tints of the rainbow.
