Galen says of the melopepon, or squash, that its juices are not so unwholesome, nor so diuretic, nor so laxative, as those of the pompion. He adds that, although far from delicious, it is not so nauseous as the pompion. On the melopepon, see Harduin’s notes on Pliny (H. N. xviii, 5.) Perhaps some of the authorities may have meant the melon by the melopepon. Galen says that some persons, from idiosyncrasy, readily digest the cucumber (σἴκυος); but he insists that it is impossible that good blood can be formed from it, and therefore he warns against the frequent use of all such fruits. Actuarius says that it forms a crude chyme, and is of a cold, humid, and indigestible nature. Celsus says that its nutritive powers are feeble. Avicenna says that its juices are bad, and prone to putrefaction. Melons are said by Averrhoes to be of a cold nature, juicy, detergent, and diuretic. Owing to the lax signification in which the names of the summer fruits are often applied by the Greek and Roman writers, we have felt considerable difficulty in distinguishing the articles treated of in this chapter. This confusion is of very ancient date, for one of the _Deipnosophists_ of Athenæus complains of the difficulty he found in comprehending the proper application of these terms, from their having been differently used by the authors who had treated of them. (ix, 14.) We have been obliged for once to abandon the guidance of Sprengel, but have done so with the greatest hesitation, and not until we had compared the descriptions of all the Greek, Latin, and Arabian authorities. Schneider points out the confusion about the use of these terms, but does not sufficiently clear it up in his Index to Theophrastus. Ludovicus Nonnius may likewise be consulted with advantage. He supposes that the pepones of the ancients were our melons; and he is also inclined to believe that the melopepon was a species of the same. (De Re Cibaria, i, 16.) For want of a better term, we have ventured to translate it the squash, although we are uncertain whether the Greeks were acquainted with this fruit, now so common in the East and in America. SECT.
