When a Medieval Monk Crowdsourced the Most Accurate Map of the World, Creating "the Google Earth of the 1450s"

If we need to know the pre­cise geo­graph­i­cal loca­tion of, say, a par­tic­u­lar church in Madrid, video arcade in Tokyo or cof­rate store in Addis Aba­ba, we will be able to fig­ure it out in a mat­ter of sec­onds. That is, in his­tor­i­cal phrases, a contemporary devel­op­ment certainly: many people remem­ber when probably the most detailed automobile­to­graph­i­cal infor­ma­tion shall we get about dis­tant lands (or for that mat­ter, maximum of our personal land) printed to us simplest its towns and main roads — assum­ing we even had an international atlas handy. Now, more youthful peo­ple take for grant­ed the knowl­fringe of no longer simply the place each and every position on this planet is, however what it looks as if, what its costs are, and what its vis­i­tors have mentioned about it.

We are living these days, in oth­er phrases, within the dream of Fra Mau­ro, the Venet­ian automobile­tog­ra­ph­er-monk of the past due Mid­dle Ages who cre­at­ed probably the most detailed and accu­fee global map to that time in human his­to­ry. “As a tender guy, Fra Mau­ro were a sol­dier and mer­chant of the famed Venice Mer­chant Fleet,” says the website online of New International Automobile­to­graph­ic. “His trav­els with the fleet across the Mediter­ranean and the Mid­dle East outcome­ed in his becom­ing inter­est­ed in map­ping, and he even­tu­al­ly set­tled within the monastery of San Michelle at the island of Mura­no, within the Venice Lagoon, the place he changed into a lay broth­er.” Within the ear­ly 1450s, “he was once com­mis­sioned by way of King Afon­so V of Por­tu­gal to cre­ate a map of the sector.”

Por­tu­gal’s will to dom­i­nate global industry, which required probably the most detailed maps pos­si­ble, was once matched by way of Fra Mau­ro’s will to gath­er infor­ma­tion about each and every cor­ner of Earth, no mat­ter how far-flung. And he may do this with­out leav­ing Venice: as Atlas Obscu­ra’s Adam Kessler writes, “Arab investors and global explor­ers handed throughout the port, giv­ing Fra Mau­ro an incom­pa­ra­ble supply of gos­sip and tall stories in regards to the global. The autumn of Con­stan­tino­ple, happen­ring a couple of years sooner than the map was once fin­ished, would even have professional­vid­ed a wealthy supply of well-trav­eled refugees, pre­sum­ably will­ing to change their sto­ries for some bread or beer.” Now not simplest did the map’s phys­i­cal cre­ation require a workforce of col­lab­o­ra­tors, the gath­er­ing of its con­tents relied upon the fif­teenth-cen­tu­ry equiv­a­lent of crowd­sourc­ing.

This chap­ter of auto­to­graph­i­cal his­to­ry invitations such tech­no­log­i­cal analo­gies: Kessler calls Fra Mau­ro’s com­plet­ed map­pa mun­di “the Google Earth of the 1450s.” Regardless of his reli­gious affil­i­a­tion with the monastery of San Michele, Fra Mau­ro’s efforts professional­duced an unprece­dent­ed­ly rad­i­cal ren­di­tion of the sector. Spoil­ing with reli­gious tra­di­tion, he did­n’t put Jerusalem within the cen­ter; “the Gar­den of Eden was once rel­e­gat­ed to an aspect­field, no longer proven in an actual geo­graph­ic loca­tion.” His scrupu­lous­ness made him the primary automobile­tog­ra­ph­er “to depict Japan as an island, and the primary Euro­pean to turn that it’s good to sail the entire approach round Africa.” Whilst his map was once “probably the most accu­fee ever made on the time,” its greater than 3,000 anno­ta­tions do con­tain plen­ty of tall stories, incessantly of lit­er­al giants. However are they actual­ly a lot much less consider­wor­thy than the aver­age twen­ty-first-cen­tu­ry person evaluate?
