Taariikh

Isbedelka lambar "2" soo martey.

Taariikhda samaysanka tiradan lambar 2 waxay dib u noqonaysaa qarniyo badan. Markii ugu horeeysay, qabiilka hindida Brahmin waxay isticmaali jireen labo xariijin oo u taagan lambar 2. Wakhti ka dib, isbedel ayay ku sameeyeen labadii xariijin ayagoo 45 degree u jeediyay (xoogaa yar qalooc ah), isla markaana gaabiyay dhererka xariijinta sare. Mudo ka dib, dadka Nagariga ayaa bedel ku sameeyay labadii xariijin ayagoo laynka sare qoloociyay isla markaana ku xidhay kan hoose.^[3] Naqshada noocani ah waxaa la qabsi ku sameeyay qabiilka Ghubar ee Carabta kuwaasi oo xariijintii hoose toosiyay tii sarena qaloociyay kana dhigay hal lambar oo is-heysta.

Wadanada reer Yurub waxay isbedel yar ku sameeyeen habka qoraalka tirada Carabiga ah, taasi oo ah aasaaska tirada aan maanta isticmaalno.^[4]
