The trigla, or mullus, as Nonnius, Harduin, Schneider, and Coray state, was the surmullet, or _mullus barbatus_ L. It is mentioned as a rare delicacy of great price by Horace (Sat. ii, 2); Juvenal (Sat. iv, 15); Martial (Xenia, 74); and Macrobius (Saturnal. iii, 16.) Athenæus says of it, “Diocles writes that the flesh of the mullus is hard.” (vii, 21.) Its liver prepared with oil and wine is said by Galen to have been esteemed as a peculiar delicacy. We need not say how much the murene was sought after by all the lovers of good eating in ancient Rome. Pliny, Martial, and Macrobius inform us that those from Sicily were in most esteem; and Brydone takes notice of the peculiar excellence of the Sicilian murenes at the time when he performed his tour through that island. According to Icesius, it is as nutritious as the eel. (Athen. vii.) He mentions that the murene was called “the Helen of suppers;” and hence, no doubt, Linnæus has named the fish _muræna Helena_. It was held in much esteem, he says, before spawning. (Ibid.) Apicius gives various receipts for the dressing of it. Pepper, wine, vinegar, and oil are ingredients in almost every one of them. The murene which was served up at the supper of Nasidienus had a sauce or soup formed of such things. (Horace, Sat. ii, 8.) It is related of Vedius Pollio, that he fed his murenes with the bodies of condemned slaves. (Plin. Hist. Nat. ix, 23, and Tertullian, De Pallio.) L. Crassus, the orator, put on mourning clothes for the death of a murene. (Macrobius, Sat. iii, 15.) The _muræna ophis_ is mentioned by Galen as having the same character as its congener. The ancients were acquainted with several species of mackerel (_scomber scomber_), which Xenocrates represents as nutritious, but unpalatable and flatulent. The anguilla, or common eel, and the congrus, or conger-eel, were despised by the Roman _gourmands_, but were greatly esteemed by the Greeks. Icesius says that eels are the best of fishes. See Athen.
