Niba utekereza ko urugamba rwabagabo rwo gukuraho umusatsi wo mumaso arirwo rugezweho, dufite amakuru yawe. Hariho ibimenyetso byubucukuzi byerekana ko, mugihe cyanyuma cyibuye, abagabo biyogoshesha ibishishwa bya flint, obsidian, cyangwa clamshell, cyangwa bakoresheje clamhells nka tewers. (Ouch.)
Nyuma yaho, abagabo bagerageje kogosha umuringa, umuringa nicyuma. Abakire bashobora kuba bafite abakozi bogosha ku bakozi, mugihe twese twasuye iduka ryogosha. Kandi, guhera mugihe cyo hagati, ushobora no gusura kogosha niba ukeneye kubagwa, kumena amaraso, cyangwa amenyo yose yakuwe. (Inyoni ebyiri, ibuye rimwe.)

Mu bihe bya vuba aha, abagabo bakoresheje urwembe rugororotse, nanone bita "gukata-umuhogo" kuko… neza, biragaragara. Igishushanyo cyacyo gisa nicyuma cyasobanuraga ko kigomba gukarurwa nigitare cyometseho cyangwa umugozi wuruhu, kandi bigasaba ubuhanga butari buke (tutibagiwe no kwibanda kuri lazeri) kugirango ukoreshe.

KUKI TWATANGIYE KWogosha AHO BWA MBERE?
Kubwimpamvu nyinshi, biragaragara. Abanyamisiri ba kera biyogoshesha ubwanwa n'umutwe, birashoboka kubera ubushyuhe kandi birashoboka ko ari inzira yo kwirinda inda. Nubwo byafatwaga nkudakuze gukura umusatsi wo mumaso, farawo (ndetse nabagore bamwe) bambara ubwanwa bwibinyoma bigana imana Osiris.

Kogosha byaje kwemerwa n'Abagereki ku ngoma ya Alexandre le Grand. Imyitozo yashishikarizwaga cyane mu rwego rwo kwirwanaho ku basirikare, ikabuza umwanzi gufata ubwanwa mu ntoki.

ITANGAZO RY'IMYIDAGADURO CYANGWA PASI YANYU?
Abagabo bagiranye urukundo-rwanga umusatsi wo mumaso kuva kera. Mu myaka yashize, ubwanwa bwagaragaye nkubusa, bwiza, ibikenewe mu idini, ikimenyetso cyimbaraga nubugome, umwanda wuzuye, cyangwa amagambo ya politiki.

Kugeza Alegizandere Mukuru, Abagereki ba kera baca ubwanwa mu gihe cy'icyunamo. Ku rundi ruhande, abasore b'Abaroma ahagana mu mwaka wa 300 mbere ya Yesu bari bafite ibirori byo "kogosha bwa mbere" bishimira ko bakuze, kandi bakura ubwanwa gusa mu gihe cy'icyunamo.

Ahagana mu gihe cya Julius Sezari, abagabo b'Abaroma bamwiganye bakuramo ubwanwa, hanyuma Hadrian, Umwami w'abami w'Abaroma kuva mu 117 kugeza mu wa 138, agarura ubwanwa mu buryo.

Abaperezida 15 ba mbere bo muri Amerika ntibagira ubwanwa (nubwo John Quincy Adams na Martin Van Buren bakinnye inyama z’intama zitangaje.) Hanyuma, Abraham Lincoln, nyiri ubwanwa buzwi cyane mu bihe byose, yatowe. Yatangiye icyerekezo gishya - abaperezida benshi bamukurikiye bafite imisatsi yo mu maso, kugeza Woodrow Wilson mu 1913. Kandi kuva icyo gihe, abaperezida bacu bose bogoshe. Kandi kubera iki? Kogosha bigeze kure.
