To this planting or involuntary colonisation, Petronius—seemingly, despite controversy, the “Elegantiæ Arbiter,” or the not altogether Admirable Crichton, of Tacitus—probably alludes: “ultimus ab oris Attractus scarus atque arata Syrtis Si quid naufragio dedit, probatur.”[370] Poets and _gourmets_ have vied in singing the praises of the fish as the daintiest of dishes—“according to the Greeks to do justice to its flesh was not easy: to speak of its trail, as it deserved, was impossible, and to throw away even its excrement was a sin.” Confirmatory of Badham reads the pronouncement of _magnus ille et subtilis helluo_, “that great and exquisite gourmet” Archestratus, who from the grandiloquence and gravity of his Epic was evidently of opinion _omne cum fidibus helluoni_![371] Epicharmus the comedian in his _Hebe’s Wedding_ (_frag._ 54, Kaibel), καὶ σκάους, τῶν οὐδὲ τὸ σκᾶρ θέμιτον ἐκβαλεῖν θεοῖς,[372] “Not even their trail is it lawful for the gods to throw away,” summarises the wild infatuation of the Greeks for the _scarus_, while from Ennius[373] some centuries later is extorted, “Quid scarus? præterii cerebrum Jovis pæne supremi: Nestoris ad patriam his capitur magnusque bonusque.” Although Pliny (IX. 29) definitely asserts “Nunc scaro datur principatus,” we find Martial within a few years dismissing the fish as of poor flavour—its only redeeming point the trail, which is excellent, “Hic scarus, æquoreis qui venit obesus ab undis, Visceribus bonus est, cetera vile sapit.” (XIII. 84).[374] In the curious and rare _Ichtyophagia_ (the omission of the second ‘h’ of the theta may be a printer’s error) by the learned Doctor Ludovicus Nonnius, published at Antwerp in 1616—a treasure-house from which I quote much and take more—an attempt is made to explain these diametrically opposed estimates. Nonnius asserts that as among the common herd only those fish which have fat flesh find favour or yield good flavour, and as the _Scarus_ possesses a drier and more flaky flesh, “a plebis illis palatis spernebatur.” This deals a nasty knock to poor Martial, who plumed himself on his taste as a gourmet, acquired (he fails to add) at the banquets and entertainments of his patrician friends or wealthy patrons. Medical controversy, rarely absent, as to wholesomeness for once hardly exists. Galen, Diphilus, Xenocrates all agree as to the _Scarus_, although the last warns us that it is “hard to pass off in perspiration!” (δυσδιαφόρητος).[375] Galen pronounces fish who haunt the rocks the most wholesome[376]: of these, the _Scarus_ is by far the best. Diphilus the Siphnian on the whole agrees, but condemns it as dangerous when fresh (!) because it hunts and feeds on the poisonous sea-hare and so frequently causes cholera morbus.[377]
