Autos de fe were celebrated in public squares or esplanades. They lasted several hours and were attended by ecclesiastical and civil authorities and drew more general public than other public executions.
In Lisbon, the Rossio square was the burning place.
Prisoners were brought in carriages among the insults of the populace. They were clothed with the infamous sambenito. If some prisoners arose the compassion of the public, goodwill bystanders would try to persuade them to repent to spare them of being burned alive.
The first auto de fe took place in Seville, Spain, in 1481, when six men and women were executed. The Inquisition enjoyed only limited power in Portugal, lasting only four years, with only one act of auto da fe in Porto (Really? What about Rossio then?. Autos de fe also took place in Mexico, Brazil, and Peru, and are recorded by contemporary historians of the Conquistadors such as Bernal Diaz. The last case of an execution by the Spanish Inquisition was a schoolmaster, Cayetano Ripoll, July 26, 1826. His trial lasted nearly two years. He was accused of being a deist, and substituting in his school the words "Praise be to God" for "Ave Maria purissima." He died calmly on the gibbet after repeating the words, "I die reconciled to God and to man." This was the last auto de fe.
