The World Map That Introduced Scientific Mapmaking to the Medieval Islamic World (1154 AD)


Cast your mind, if you will, to the city of Ceu­ta. If you’ve nev­er heard of it, or can’t quite recall its loca­tion, you can eas­i­ly find out by search­ing for it on your map appli­ca­tion of choice. Back in the twelfth cen­tu­ry, how­ev­er, you might have had to con­sult an image of the known world engraved on a 300-pound, six-and-a-half-foot wide sil­ver disk — but then, if you had access to that disk, you’d know full well where Ceu­ta was in the first place. For it belonged to King Roger II of Sici­ly, who’d com­mis­sioned it from the geo­g­ra­ph­er, trav­el­er, and schol­ar Abū Abdal­lāh Muham­mad ibn Muham­mad ibn Abdal­lāh ibn Idrīs al-sharif al-Idrīsī — more suc­cinct­ly known as Muham­mad al-Idrisi — per­haps Ceu­ta’s most accom­plished son.

“Al-Idrisi stud­ied in Cor­do­ba and trav­eled wide­ly as a young man, vis­it­ing Asia Minor, Hun­gary, the French Atlantic coast, and even as far north as York, Eng­land,” writes Big Think’s Frank Jacobs. In 1138, Roger II “invit­ed al-Idrisi to his court at Paler­mo, pos­si­bly to explore whether he could install the Mus­lim noble­man as a pup­pet ruler in the bits of North Africa under his domin­ion, or in Spain, which he hoped to con­quer.” The project that result­ed from this meet­ing, fif­teen years of work lat­er, was “a new and accu­rate map of the world.” In addi­tion to knowl­edge gained on his own exten­sive trav­els, Al-Isidiri con­sult­ed ancient sources like Ptolemy’s Geog­ra­phy and “inter­viewed ship’s crews and oth­er sea­soned trav­el­ers, but retained only those sto­ries on which all were in agree­ment,” leav­ing out the myth­i­cal tribes and fan­tas­ti­cal crea­tures.

In addi­tion to the grand disk, Al-Idrisi cre­at­ed an atlas con­sist­ing of 70 detailed, anno­tat­ed maps called Nuzhat al-mushtāq fi’khtirāq āl-āfāq. That Ara­bic title has been var­i­ous­ly trans­lat­ed — “the book of pleas­ant jour­neys into far­away lands,” “the excur­sion of the one who yearns to pen­e­trate the hori­zons,” “the excur­sion of one who is eager to tra­verse the regions of the world” — but in Latin, the book was sim­ply called the Tab­u­la Roge­ri­ana. Alas, writes Jacobs, “the orig­i­nal Latin ver­sion of the atlas (and the sil­ver disk) were destroyed in 1160 in the chaos of a coup against William the Wicked, Roger’s unpop­u­lar son and suc­ces­sor.” Still, Al-Idrisi did man­age to bring the Ara­bic ver­sion back with him to North Africa, where it became an influ­en­tial exam­ple of sci­en­tif­ic car­tog­ra­phy for the Islam­ic world.

A glance at the Library of Con­gress’ Ger­man fac­sim­i­le from 1928 at the top of the post reveals that Al-Idrisi’s world map looks quite unlike the ones we know today. He put south, not north, at the top, the bet­ter for Islam­ic con­verts to ori­ent them­selves toward Mec­ca. “His Europe is sketchy, his Asia amor­phous, and his Africa man­ages to be both par­tial and over­sized,” Jacobs notes, but nev­er­the­less, he got a lot right, includ­ing such lit­tle-known regions as the king­dom of Sil­la (locat­ed in mod­ern-day Korea) and cal­cu­lat­ing — approx­i­mate­ly, but still impres­sive­ly — the cir­cum­fer­ence of the entire Earth. We might con­sid­er pay­ing trib­ute to Al-Idrisi’s achieve­ments by mak­ing a trip to his home­town (a Span­ish-held city, for the record, at the very tip of Africa north-east of Moroc­co), which seems like a pleas­ant place to spend a few weeks — and a promis­ing start­ing point from which to pen­e­trate a few hori­zons of our own.
