Time,then,andtheheavencameintobeingatthesameinstantin orderthat,havingbeencreatedtogether,ifevertherewastobea dissolutionofthem,theymightbedissolvedtogether。Itwasframed afterthepatternoftheeternalnature,thatitmightresemblethis asfaraswaspossible;forthepatternexistsfrometernity,and thecreatedheavenhasbeen,andis,andwillbe,inalltime。Such wasthemindandthoughtofGodinthecreationoftime。Thesunand moonandfiveotherstars,whicharecalledtheplanets,were createdbyhiminordertodistinguishandpreservethenumbersof time;andwhenhehadmade—theirseveralbodies,heplacedtheminthe orbitsinwhichthecircleoftheotherwasrevolving—inseven orbitssevenstars。First,therewasthemoonintheorbitnearestthe earth,andnextthesun,inthesecondorbitabovetheearth;then camethemorningstarandthestarsacredtoHermes,movingin orbitswhichhaveanequalswiftnesswiththesun,butinan oppositedirection;andthisisthereasonwhythesunandHermes andLuciferovertakeandareovertakenbyeachother。Toenumeratethe placeswhichheassignedtotheotherstars,andtogiveallthe reasonswhyheassignedthem,althoughasecondarymatter,would givemoretroublethantheprimary。Thesethingsatsomefuture time,whenweareatleisure,mayhavetheconsiderationwhichthey deserve,butnotatpresent。 Now,whenallthestarswhichwerenecessarytothecreationoftime hadattainedamotionsuitabletothem,—andhadbecomeliving creatureshavingbodiesfastenedbyvitalchains,andlearnttheir appointedtask,movinginthemotionofthediverse,whichis diagonal,andpassesthroughandisgovernedbythemotionofthe same,theyrevolved,someinalargerandsomeinalesserorbit—those whichhadthelesserorbitrevolvingfaster,andthosewhichhadthe largermoreslowly。Nowbyreasonofthemotionofthesame,those whichrevolvedfastestappearedtobeovertakenbythosewhichmoved sloweralthoughtheyreallyovertookthem;forthemotionofthe samemadethemallturninaspiral,and,becausesomewentoneway andsomeanother,thatwhichrecededmostslowlyfromthesphereof

fire,whichwenowcallthesun,inthesecondfromtheearthofthese orbits,thatitmightgivelighttothewholeofheaven,andthat theanimals,asmanyasnatureintended,mightparticipatein number,learningarithmeticfromtherevolutionofthesameandthe like。Thusthen,andforthisreasonthenightandthedaywere created,beingtheperiodoftheonemostintelligentrevolution。 Andthemonthisaccomplishedwhenthemoonhascompletedherorbit andovertakenthesun,andtheyearwhenthesunhascompletedhisown orbit。Mankind,withhardlyanexception,havenotremarkedthe periodsoftheotherstars,andtheyhavenonameforthem,anddonot measurethemagainstoneanotherbythehelpofnumber,andhencethey canscarcelybesaidtoknowthattheirwanderings,beinginfinite

degreesofswiftness,areaccomplishedtogetherandattaintheir completionatthesametime,measuredbytherotationofthesame andequallymoving。Afterthismanner,andforthesereasons,came

Thusfaranduntilthebirthoftimethecreateduniversewasmade inthelikenessoftheoriginal,butinasmuchasallanimalswere notyetcomprehendedtherein,itwasstillunlike。Whatremained, thecreatorthenproceededtofashionafterthenatureofthepattern。 Nowasintheidealanimalthemindperceivesideasorspeciesofa certainnatureandnumber,hethoughtthatthiscreatedanimalought

thefourth,thepedestrianandlandcreatures。Oftheheavenlyand divine,hecreatedthegreaterpartoutoffire,thattheymightbe thebrightestofallthingsandfairesttobehold,andhefashioned

beforeus,whichinvolvesapreliminaryenquiryintothegenerationof thebodyanditsmembers,andastohowthesoulwascreated—for whatreasonandbywhatprovidenceofthegods;andholdingfastto probability,wemustpursueourway。 First,then,thegods,imitatingthesphericalshapeofthe universe,enclosedthetwodivinecoursesinasphericalbody,that, namely,whichwenowtermthehead,beingthemostdivinepartofus andthelordofallthatisinus:tothisthegods,whentheyput togetherthebody,gavealltheothermemberstobeservants, consideringthatitpartookofeverysortofmotion。Inorderthen thatitmightnottumbleaboutamongthehighanddeepplacesofthe earth,butmightbeabletogetovertheoneandoutoftheother, theyprovidedthebodytobeitsvehicleandmeansoflocomotion; whichconsequentlyhadlengthandwasfurnishedwithfourlimbs extendedandflexible;theseGodcontrivedtobeinstrumentsof locomotionwithwhichitmighttakeholdandfindsupport,andsobe abletopassthroughallplaces,carryingonhighthedwelling—place ofthemostsacredanddivinepartofus。Suchwastheoriginof legsandhands,whichforthisreasonwereattachedtoeveryman; andthegods,deemingthefrontpartofmantobemorehonourable andmorefittocommandthanthehinderpart,madeustomovemostly inaforwarddirection。Whereforemanmustneedshavehisfrontpart

ofthesoul,andtheyappointedthispart,whichhasauthority,to bebynaturethepartwhichisinfront。Andoftheorgansthey firstcontrivedtheeyestogivelight,andtheprincipleaccordingto whichtheywereinsertedwasasfollows:Somuchoffireaswould notburn,butgaveagentlelight,theyformedintoasubstanceakin tothelightofevery—daylife;andthepurefirewhichiswithinus andrelatedtheretotheymadetoflowthroughtheeyesinastream smoothanddense,compressingthewholeeye,andespeciallythecentre part,sothatitkeptouteverythingofacoarsernature,and allowedtopassonlythispureelement。Whenthelightofday surroundsthestreamofvision,thenlikefallsuponlike,andthey coalesce,andonebodyisformedbynaturalaffinityinthelineof vision,whereverthelightthatfallsfromwithinmeetswithan externalobject。Andthewholestreamofvision,beingsimilarly affectedinvirtueofsimilarity,diffusesthemotionsofwhatit touchesorwhattouchesitoverthewholebody,untiltheyreachthe soul,causingthatperceptionwhichwecallsight。Butwhennight comesonandtheexternalandkindredfiredeparts,thenthestreamof

Andrightappearsleftandleftright,becausethevisualrayscome intocontactwiththeraysemittedbytheobjectinamanner contrarytotheusualmodeofmeeting;buttherightappearsright,

Allthesearetobereckonedamongthesecondandco—operative causeswhichGod,carryingintoexecutiontheideaofthebestas faraspossible,usesashisministers。Theyarethoughtbymostmen
