Ptolemy, writing about the year 150, unconsciously bears out to some extent what Tacitus had said of Ireland's harbours being better known than those of Britain, for he has left behind him a more accurate account of Ireland than of Britain, giving in all over fifty Irish names, about nine of which have been identified, and mentioning the names of two coast towns, seven inland towns, and seventeen tribes, some of which, as we have said, nearly resemble the names of tribes in Britain and North Gaul. Solinus, about A.D. 238, is the first to tell us that Hibernia has no snakes--observe this curious pre-Patrician evidence which robs our national saint of one of his laurels--saying, like Pomponius Mela, that it has luxurious pastures, and adding the curious intelligence that, "warlike beyond the rest of her sex, the Hibernian mother places the first morsel of food in her child's mouth with the point of the sword." Eumenius mentions the Hibernians about the year 306 in his panegyric on Constantine, saying that until now the Britons had been accustomed to fight only Pictish and Hibernian enemies. In 378 Ammianus Marcellinus mentions the Irish under the name of Scots, saying that the Scotti and Attacotti[12] commit dreadful depredations in Britain, and Claudian a few years later speaks rather hyperbolically of the Irish invasion of Britain; "the Scot (_i.e._, the Irishman)," he says, "moved all Ierne against us, and the Ocean foamed under his hostile oars--a Roman legion curbs the fierce Scot, through Stilicho's care I feared not the darts of the Scots--Icy Erin wails over the heaps of her Scots."[13] The Irish expeditions against both Gaul and Britain became more frequent towards the end of the fourth century, and at last the unfortunate Britons, driven to despair, and having in vain appealed to the now disorganised Romans to aid them, sooner than stand the fury of the Irish and Picts threw themselves into the arms of the Saxons.[14]
