Quadrivium!

Arithmetic! Geometry! Astronomy! Music!

Whereas! the! Trivium! focuses! on! speech,! argument! and! the! ordering! of!thought,! the!Quadrivium! focuses! on!mathematics.! This! includes!music! in!the! medieval! period,! with! its! emphasis! on! proportion! and! ratio,! a!theoretical!subject!as!much!as!a!practical.!Grosseteste’s!scientific!works!fall,!broadly! speaking,! into! the!mathematical! arts.!

Grosseteste! sets! out! the!issue! very! clearly! in! the!opening! sentence:!'color! est! lux! incorporata! perspicuum'!‘colour!is!light!incorporated!in!a!diaphanous!medium’.!What! colour! is,! and! how! does! it!move! from! blackness! to! whiteness,!occupies! him! for! the! rest! of! this! dense,!exquisitely! structured! discussion.! What!emerges! is! Grosseteste’s! conception! of! a!threeCdimensional! colourCspace,! with! very!interesting! analogues! to! modern! colour!theory.! The! treatise! seems! to! have! been!written! in! or! around! 1225,! based! on! the!texts!to!which!Grosseteste!seems!to!refer,!in!particular!that!of!Averroes!(the!Islamic!philosopher!from!Cordoba,!Ibn!Rushd,!d.!1198,!pictured!above).!The!manuscript! history! was! intriguing! and! exiting! to! uncover:! a! piece! of!detective!work!with!missing!words!found,!and!numerical!problems!solved.!
