 Allegations were made that Torquemada had exploited and abused the Indian workforce and had severely beaten one particular labourer "almost to death" ("a punto de muerte").An official investigation was initiated by the Archbishop of México on 16 February 1605, but there is no record of the outcome and there was no interruption to Torquemada's work on the church.It was while he was guardian of the convent of Tlatelolco that Torquemada also put in hand the organisation of the materials he had been gathering for many years previously, and (between 1605 and 1612) their redaction into the great work he had been projecting - the history of the aboriginal nations of New Spain, and their conquest and evangelisation by the Spanish.
