Procopius also (de Ædificiis, lib. v.) makes Augila _four_ days’ journey from Borium, (the Borium _Oppidum_, at the bottom of the Gulf.)] [Footnote 13: Ουτο μεν μεχρι της Τριτωνιδος λιμνης απ᾽ Αιγυπτου νομαδες εισι κρεοφαγοι τε και γαλακτοποται Λιβυες· και θηλεων τε βοων ουτοι γευομενοι, &c.—Melp. ρπςʹ.] [Footnote 14: Melp. ρπζ.—Sallust has observed of this coast and its inhabitants:— “Mare sævum, importuosum. Ager frugum fertilis, bonus pecori, arbori infecundus: cœlo, terraque penuria aquarum: genus hominum salubri corpore, velox, patiens laborum: plerosque senectus dissolvit, nisi qui ferro, aut a bestiis interiere. Nam morbus haud sæpe quenquam superat, ad hoc malefici generis plurima animalia.”—(Bell. Jugurth. § 17.) This account agrees very well with that of Herodotus; but the description which Sallust afterwards gives of the country where the Philænean altars were placed, conveys too much the idea of a flat sandy plain.] [Footnote 15: That is, on the surface; for in most sandy deserts water may be found by digging.] [Footnote 16: Ουτοι μεν ὁι παραθαλασσιοι των Νομαδων λιβυων ειρεαται. υπερ δε τουτων, ες μεσογαιαν, η θηριωδης εστι λιβυη· υπερ δε της θηριωδεος οφρυη ψαμμης κατηκει, παρατεινουσα απο θηβεων των Αιγυπτιεων επι Ηρακληιας στηλας. (Melp. ρπαʹ.)] [Footnote 17: Strabo seems to place the Nasamones farther inland, whither they were probably driven by the Cyreneans subsequent to the account of Herodotus. Την δε υπερκειμενην εν βαθει χωραν της Συρτεως και της Κυρηναιας κατεχουσιν ὁι Λιβυες παραλυπρον και αυχμηραν· πρωτον μεν ὁι Νασαμωνες, επειτα ψυλλοι και τινες γαιτουλοι, επειτα Γαραμαντες· (Lib. 17. p. 838.)] [Footnote 18: The want of accurate information which has hitherto obtained, respecting the Gulf and the Shores of the Greater Syrtis, has not only occasioned their being incorrectly laid down in modern maps, but has necessarily subjected the observations of modern writers upon them to errors which would not otherwise have been made. In alluding to the breadth across the mouth of the Greater Syrtis, Major Rennell has remarked as follows:— “Scylax reckons it a passage of three days and nights across its mouth; which, however, measures no more than one hundred and eighty geographic miles on the best modern maps. This allows about sixty miles for each day and night collectively.” But the actual distance across the Gulf, from Mesurata to Bengazi, is two hundred and forty-six geographic miles, instead of one hundred and eighty, and this would give a rate of eighty-six miles per day (considered as twenty-four hours).
