In Saint Gall's historiography, Kerhart comes out badly: His squandering of abbey property and the ruining of its breed is said to have caused a divide in the convent. One party, consisting ofolderconventuals who closely followed the rules, subsequently complained about Kerhart to Emperor Otto. A certain Duke Muozo had to come to his rescue and prevent the trial. Afterwards, Kerhart apparently ruled even worse than before.
