If we want to know the preÂcise geoÂgraphÂiÂcal locaÂtion of, say, a parÂticÂuÂlar church in Madrid, video arcade in Tokyo or cofÂfee shop in Addis AbaÂba, we can figÂure it out in a matÂter of secÂonds. This is, in hisÂtorÂiÂcal terms, a recent develÂopÂment indeed: many of us rememÂber when the most detailed carÂtoÂgraphÂiÂcal inforÂmaÂtion we could get about disÂtant lands (or for that matÂter, most of our own land) revealed to us only its cities and major roads — assumÂing we even had a world atlas at hand. Now, younger peoÂple take for grantÂed the knowlÂedge of not just where every place in the world is, but what it looks like, what its prices are, and what its visÂiÂtors have said about it.
We live today, in othÂer words, in the dream of Fra MauÂro, the VenetÂian carÂtogÂraÂphÂer-monk of the late MidÂdle Ages who creÂatÂed the most detailed and accuÂrate world map to that point in human hisÂtoÂry. “As a young man, Fra MauÂro had been a solÂdier and merÂchant of the famed Venice MerÂchant Fleet,” says the site of New World CarÂtoÂgraphÂic. “His travÂels with the fleet around the MediterÂranean and the MidÂdle East resultÂed in his becomÂing interÂestÂed in mapÂping, and he evenÂtuÂalÂly setÂtled in the monastery of San Michelle on the island of MuraÂno, in the Venice Lagoon, where he became a lay brothÂer.” In the earÂly 1450s, “he was comÂmisÂsioned by King AfonÂso V of PorÂtuÂgal to creÂate a map of the world.”
PorÂtuÂgal’s will to domÂiÂnate world trade, which required the most detailed maps posÂsiÂble, was matched by Fra MauÂro’s will to gathÂer inforÂmaÂtion about every corÂner of Earth, no matÂter how far-flung. And he could do that withÂout leavÂing Venice: as Atlas ObscuÂra’s Adam Kessler writes, “Arab traders and world explorÂers passed through the port, givÂing Fra MauÂro an incomÂpaÂraÂble source of gosÂsip and tall tales about the world. The fall of ConÂstanÂtinoÂple, occurÂring a few years before the map was finÂished, would also have proÂvidÂed a rich source of well-travÂeled refugees, preÂsumÂably willÂing to swap their stoÂries for some bread or beer.” Not only did the map’s physÂiÂcal creÂation require a team of colÂlabÂoÂraÂtors, the gathÂerÂing of its conÂtents relied upon the fifÂteenth-cenÂtuÂry equivÂaÂlent of crowdÂsourcÂing.
This chapÂter of carÂtoÂgraphÂiÂcal hisÂtoÂry invites such techÂnoÂlogÂiÂcal analoÂgies: Kessler calls Fra MauÂro’s comÂpletÂed mapÂpa munÂdi “the Google Earth of the 1450s.” Despite his reliÂgious affilÂiÂaÂtion with the monastery of San Michele, Fra MauÂro’s efforts proÂduced an unpreceÂdentÂedÂly radÂiÂcal renÂdiÂtion of the world. BreakÂing with reliÂgious traÂdiÂtion, he didÂn’t put Jerusalem in the cenÂter; “the GarÂden of Eden was relÂeÂgatÂed to a sideÂbox, not shown in a real geoÂgraphÂic locaÂtion.” His scrupuÂlousÂness made him the first carÂtogÂraÂphÂer “to depict Japan as an island, and the first EuroÂpean to show that you could sail all the way around Africa.” While his map was “the most accuÂrate ever made at the time,” its more than 3,000 annoÂtaÂtions do conÂtain plenÂty of tall tales, often of litÂerÂal giants. But are they realÂly much less trustÂworÂthy than the averÂage twenÂty-first-cenÂtuÂry user review?
