iNFLUE.VCE OF THE PTOLEMAIC EPOCr. HS 



Tlie history of the contemplation of the universt embraces 

 the enumeration of all the means which have hronght nations 

 into closer contact with one another, rendered larger portions 

 of the earth more accessible, and thus extended the sphere of 

 human knowledge. One of the most important of these 

 means was the opening of a road of communication from the 

 Red Sea to the Mediterranean by means of the Nile. At the 

 point where the scarcely-connected continents present a line 

 of bay-like indentations, the excavation of a canal was begun, 

 if not by Sesostris (Rameses Miamoun), to whom Aristotle and 

 Strabo ascribe the undertaking, at any rate by Neku, although 

 the work was relinquished in consequence of the threaten- 

 ins: oracular denunciations directed against it by the priests. 

 Herodotus saw and described a canal completed by Darius 

 Hystaspcs, one of the Achaemenidse, v/hich entered the Nile 

 somewhat above Bubastus. This canal, after having fallen 

 into decay, was restored by Ptolemy Philadelphus in so perfect 

 a manner that, although (notwithstanding the skillful arrange- 

 ment of sluices) it was not navigable at all seasons of the 

 year, it nevertheless contributed to facilitate Ethiopian, Ara 

 bian, and Indian commerce at the time of the Roman domin- 

 ion under Marcus xlurelius, or even as late as Septimius Se- 

 verus, and, therefore, a century and a half after its construc- 

 tion. A similar object of furthering international communi 

 cation through the Red Se^ led to a zealous prosecution of 

 the works necessary for formihg a harbor in Myos Hormos and 

 Berenice, which was connected with Coptos by means of an 

 admirably made artificial road.* 



All these various mercantile and scientific enterprises of ihe 

 Lagides were based on an irrepressible striving to acquire nev^ 

 territories and penetrate to distant regions, on an idea of con- 

 nection and unity, and on a desire to open a wider field of 

 action by their commercial and political relations. This di 

 rection of the Hellenic mind, so fruitful in results, and which 

 had been long preparing in silence, was manifested, under its 



itself called Hippalus, and a portion of the Erythrean or Indian Ocean 

 was known as the Sea of Hippalus. Letronne, in the Journal des So'
