Book 21 › Section 1
1. Dalmatius, the tribune and notary, summoned me by the orders of your Clemency, as he asserted, demanding that I should also choose judges, as Auxentius had done. He did not mention the names of those who had been asked for, but he added that there was to be a discussion in the consistory, and that the judgment of your piety would give the decision.
