It is therefore scarce worth while to examine in detail the simple and varying forms of this period, except as we shall find them interesting in comparison with later practice. The desired uniformity was gradually attained by the Suprema which, under the independent organization of the Spanish Holy Office, developed an elaborate system of procedure, set forth in the Instructions of 1561 and furnished, in 1568, with all necessary formulas in the _Orden de Processar_ of Pablo García. Subject to such changes as subsequent experience demanded, this remained the standard to the last and was followed, with more or less exactitude by the tribunals. * * * * * When the accused was thrown into the secret prison his case, in the hurry of the earlier period, was heard and despatched with promptitude, but subsequently it became the custom for the inquisitors to exercise their discretion as to when they would call him before them, and we shall see what exasperating and calculated delays they sometimes interposed. He could, however, ask for an audience at any time, and it was an invariable rule to grant such requests, for the reason that he might have an impulse to repent and confess which might be transitory. Such audiences, however, did not count in the progress of the case. When summoned to his first regular audience, he was sworn to tell the truth in this and all future hearings and to keep silence as to all that he might see or hear, and as to everything connected with his own affair. He was made to declare his name, his age, his birthplace, his occupation and the length of time since his arrest. After these formalities, if the case was one of heresy, there came an investigation into his genealogy. This, which accumulated a mass of information as to all infected families, and facilitated greatly researches into limpieza, was not a feature of the early trials; in those of from 1530 to 1540, it was still very informal, but by the middle of the century it had become minute, extending back to two generations and including all uncles, aunts and cousins, describing of what race they were, whether any of them had been tried by the Inquisition and, if so, how punished. The punctilious observance of this takes a somewhat ludicrous aspect in the trial at Lima, in 1763, of a Mandingo negro slave for superstitious cures. He was seventy years of age and had been brought from Guinea when a child, but was interrogated minutely as to parents and grandparents, uncles and aunts, and was made to declare that they were all of the race and caste of negroes, and that none of them had been penanced, reconciled or punished by the Inquisition.[104] The accused was then interrogated as to his baptism, confirmation and observance of the rites of religion; he was made to sign and cross himself, repeat the creed and usual prayers, and finally to give an account of his past life.
