One thing in Pliny’s favor as a compiler, besides his personal industry, unflagging interest, and apparently abundant supply of clerical assistance, is his full and honest statement of his authorities, although he adds that he has caught many authors transcribing others verbatim without acknowledgment. He has, however, great admiration for many of his authorities, exclaiming more than once at the care and diligence of the men of the past who have left nothing untried or unexperienced, from trackless mountain tops to the roots of herbs.[130] Sometimes, nevertheless, he disputes their assertions. For instance, Hippocrates said that the appearance of jaundice on the seventh day in fever is a fatal sign, “but we know some who have lived even after this.”[131] Pliny also scolds Sophocles for his falsehoods concerning amber.[132] It may seem surprising that he should expect strict scientific truth from a dramatic poet, but Pliny, like many medieval writers, seems to regard poets as good scientific authorities. In another passage he accepts Sophocles’ statement that a certain plant is poisonous, rather than the contrary view of other writers, saying “the authority of so prominent a man moves me against their opinions.”[133] He also cites Menander concerning fish and, like almost all the ancients, regards Homer as an authority on all matters.[134] Pliny sometimes cites the works of King Juba of Numidia, than whom there hardly seems to have been a greater liar in antiquity.[135] He stated among other things in a work which he wrote for Gaius Caesar, the son of Augustus, that a whale six hundred feet long and three hundred and sixty feet broad had entered a river in Arabia.[136] But where should Pliny turn for sober truth? The Stoic Chrysippus prated of amulets;[137] treatises ascribed to the great philosophers Democritus and Pythagoras[138] were full of magic; and in the works of Cicero he read of a man who could see for a distance of one hundred and thirty-five miles, and in Varro that this man, standing on a Sicilian promontory, could count the number of ships sailing out of the harbor of Carthage.[139] [Sidenote: His lack of arrangement and classification.]
