▁G is è la ▁was ▁abb ess . ▁The ▁n uns ’ ▁surv iving ▁texts ▁include ▁parts ▁of ▁the ▁C ologne ▁manuscript s ▁of ▁August ine ’ s ▁Comment ary ▁on ▁the ▁Ps al ms ▁( D omb ibli othek ▁ 6 3 , ▁ 6 5 ▁and ▁ 6 7 ), ▁E use b ius ’ ▁E cc les iast ical ▁History , ▁a ▁fragment ▁of ▁Is id ore ▁of ▁Se ville ’ s ▁Et ym ologia e ▁and ▁various ▁other ▁works ▁by ▁the ▁bishop , ▁as ▁well ▁as ▁a ▁copy ▁of ▁the ▁Dialog ues ▁of ▁Gregory ▁the ▁Great ▁and ▁a ▁fragment ▁of ▁his ▁Hom ilia ▁in ▁evangel ium . ▁Many ▁of ▁the ▁manuscript s ▁are ▁signed ▁by ▁women , ▁such ▁as ▁Gir bal da , ▁G isl id is , ▁Ag le berta , ▁Ad ru h ic , ▁Alt ild is , ▁E use bia ▁and ▁V era , ▁all ▁in ▁a ▁similar ▁script . ▁This ▁indicates ▁the ▁existence ▁of ▁a ▁collect ive , ▁working ▁at ▁Ch elles ’ ▁script or ium . ▁Ros am ond ▁McK itter ick ▁has ▁suggested ▁that ▁the ▁manuscript s ’ ▁high ▁quality ▁indicates ▁that ▁the ▁scri bes ▁at ▁Ch elles ▁were ▁tal ented ▁and ▁understood ▁the ▁texts ▁they ▁were ▁copying . ▁The ▁fact ▁that ▁so ▁many ▁of ▁these ▁texts ▁were ▁author itative ▁works ▁of ▁the ▁Catholic ▁Church , ▁written ▁by ▁early ▁the olog ians , ▁also ▁l ends ▁McK itter ick ▁to ▁suggest ▁that ▁the ▁scri bes ▁were ▁well - ed uc ated .
