30.ThehistoryofresponsestotheworkoftheartistSandroBotticelli(1444—1510)suggeststhatwidespreadappreciationbycriticsisarelativelyrecentphenomenon.Writingin1550,VasariexpressedanuneasewithBotticelli'swork,admittingthattheartistfittedawkwardlyintohisevolutionaryschemeofthehistoryofart.Overthenexttwocenturies,academicarthistoriansdefamedBotticelliinfavorofhisfellowsFlorentine,Michelangelo.Evenwhenanti-academicarthistoriansoftheearlynineteenthcenturyrejectedmanyofthestandardsofevaluationadoptedbytheirpredecessors,Botticelli'sworkremainedoutsideofacceptedtaste,pleasingneitheramateurobserversnorconnoisseurs.(Manyofhisbestpaintings,however,remainedhiddenawayinobscurechurchesandprivatehomes.)

TheprimaryreasonforBotticelli'sunpopularityisnotdifficulttounderstand:mostobservers,upuntilthemid-nineteenthcentury,didnotconsiderhimtobenoteworthy,becausehiswork,forthemostpart,didnotseemtotheseobserverstoexhibitthetraditionalcharacteristicsofthefifteenth-centuryFlorentineart.Forexample,Botticellirarelyemployedthetechniqueofstrictperspectiveand,unlikeMichelangelo,neverusedchiaroscuro.

AnotherreasonforBotticelli'sunpopularitymayhavebeenthathisattitudetowardthestyle.ofclassicalartwasverydifferentfromthatofhiscontemporaries.Althoughhewasthoroughlyexposedtoclassicalart,heshowedlittleinterestinborrowingfrom,theclassicalstyle.Indeed,itisparadoxicalthatapainteroflarge-scaleclassicalsubjectsadoptedastyle.thatwas.onlyslightlysimilartothatofclassicalart.

Inanycase,whenviewersbegantoexaminemorecloselytherelationshipofBotticelli'sworktothetraditionofthefifteenthcenturyHorentineart,hisreputationbegantogrow.AnalysesandassessmentsofBotticellimadebetween1850and1870bytheartistsofthePre-Raphaelitemovement,aswellasbythewriterPater(althoughhe,unfortunately,basedhisassessmentonanincorrectanalysisofBotticelli'spersonality),inspiredanewappreciationofBotticellithroughouttheEnglish-speakingworld.YetBotticelli'swork,especiallytheSistinefrescoes,didnotgenerateworldwideattentionuntilitwasfinallysubjectedtoacomprehensiveandscrupulousanalysisbyHomein1908.Homerightlydemonstratedthatthefrescoessharedimportantfeatureswithpaintingsbyotherfifteenth-centuryFlorentines—featuressuchasskillfulrepresentationofanatomicalproportions,andofthehumanfigureinmotion.However,Homearguedthat.Botticellididnottreatthesequalitiesasendsinthemselves—rather,thatheemphasizedcleardepletionofastory,auniqueachievementandonethatmadethetraditionalFlorentinequalitieslesscentral.

BecauseofHome'semphasiscrucialtoanystudyofart,thetwentiethcenturyhascometoappreciateBotticelli'sa-chievements.
