　　BeforeAlexander，thepeopleborderingontheRedSeatradedonlyinthissea，andinthatofAfrica。TheastonishmentwhichfilledtheglobeatthediscoveryoftheIndianSea，underthatconqueror，isasufficientproofofthis。Ihaveobserved[21]thatbullionwasalwayscarriedtotheIndies，andneveranybroughtthence；nowtheJewishfleets，whichbroughtgoldandsilverbythewayoftheRedSea，returnedfromAfrica，andnotfromtheIndies。[22]

　　ThePersianswereentirestrangerstonavigation。WhentheyhadsubduedEgypt，theyintroducedthesamespiritintothatcountryasprevailedinPersia：hence，sogreatwasthesupinenessofthePersiansinthisrespect，thattheGreciankingsfoundthemquitestrangers，notonlytothecommerceoftheTyrians，Idumeans，andtheJewsontheocean，buteventothenavigationoftheRedSea。IamapttothinkthatthedestructionofthefirstTyrebyNebuchadnezzar，togetherwiththesubversionofseveralpettynationsandtownsborderingontheRedSea，hadobliteratedalltheirformerknowledgeofcommerce。
　　Egypt，atthetimeofthePersianmonarchy，didnotfronttheRedSea；
　　itcontainedonlythatlongnarrowneckoflandwhichtheNilecoverswithitsinundations，andisenclosedonbothsidesbyachainofmountains。[49]Theywere，therefore，underthenecessityofmakingaseconddiscoveryoftheoceanandtheRedSea；andthisdiscoveryengagedthecuriosityoftheGrecianmonarchs。

　　ThekingsofSyrialeftthecommerceofthesouthtothoseofEgypt，andattachedthemselvesonlytothenortherntrade，whichwascarriedonbymeansoftheOxusandtheCaspianSea。Theythenimaginedthatthisseawaspartofthenorthernocean；andAlexander，[52]sometimebeforehisdeath，hadfittedoutafleet[53]inordertodiscoverwhetheritcommunicatedwiththeoceanbytheEuxineSea，orsomeothereasternseatowardsIndia。Afterhim，SeleucusandAntiochusappliedthemselvestomakediscoveriesinit，withparticularattention；andwiththisviewtheyscoureditwiththeirfleets。[54]ThatpartwhichSeleucussurveyedwascalledtheSeleucidianSea；thatwhichAntiochusdiscoveredreceivedthenameoftheSeaofAntiochus。Attentivetotheprojectstheymighthaveformedonthatside，theyneglectedtheseasonthesouth；whetheritwasthatthePtolemies，bymeansoftheirfleetsontheRedSea，hadalreadybecomethemastersofit，orthattheydiscoveredaninvincibleaversioninthePersiansagainstengaginginmaritimeaffairs。ThesoutherncoastsofPersiasuppliedthemwithnoseamen；therehadbeennoneinthoseparts，excepttowardsthelatterendofAlexander’sreign。
