Meanwhile the masses of papers had been accumulating more rapidly than ever. In 1570 the Suprema had ordered nine books to be kept--one of the commissions of officials, their oaths and royal provisions, one of commissioners and familiars with full details, one of the votes in the consultas de fe, one of letters from the Suprema and another of letters to it, one recording the inspections made of the prisons, one of the orders issued on the receiver, one of the pecuniary penances inflicted and one of the autos de fe, with statements as to the culprits and their punishments. Besides these the alcaide of the prison was to keep lists of those relaxed and penanced with three indexes. All this was exclusive of the voluminous records of the trials which it was the duty of the fiscal to keep in order.[760] Then, in order to accommodate the increasing bulk, it was ordered, in 1566 and 1572, that there should be four apartments in the camara del secreto, one for pending cases, one for suspended ones, one for those finished, divided into the relaxed, the reconciled and the penanced, and the fourth for papers concerning commissioners and familiars and _informaciones de limpieza_.[761] In 1635, alphabetical lists of all persons tried were ordered to be kept, with dates and references to the papers of the case, commencing with 1620. The order had to be repeated in 1636 and 1638, with further instructions in 1644, and these lists furnished additional means for tracing the antecedents and kindred of those who were brought before the tribunals.[762] But more potent than the mandates of the Suprema to keep the archives in order and thoroughly indexed was the mania which arose for limpieza, or purity of blood which, as we shall see hereafter, pervaded all classes and furnished a source of very profitable business to the officials, for the Inquisition was the ultimate arbiter and its records contained the evidence.
