The strength of her body fitted her to support the greatest fatigue, the temper of her mind to brave the greatest dangers, whilst the firmness of her character made her disdain to submit to the king or to his minister. Nature had also planted in her bosom the shoots of the noblest passions--passions, alas! which, as they are well or ill directed, form the greatest men, or the most atrocious villains. Mistress of immense riches, her liberal spirit induced her to bestow them freely; whilst her superior judgment taught her to set bounds to her generosity. Thus endowed with qualities both of body and mind, so infinitely above those of the duke d'Aveiro, the marchioness soon became the life and soul of the conspiracy, which she conducted with the most wonderful skill and address. Her principal accomplices were chosen from the members of her own family, but her insinuating manners gained her several partizans, not only in the highest, but even in the lowest ranks of the people. Her conduct, in the mean time, was of a very extraordinary nature, since she never endeavoured to conceal from the prime minister the hatred she bore him, nor failed speaking of him openly, in terms of the greatest contempt. The sovereign himself was not treated with more indulgence; he became the subject of the most poignant satire, and the bitterest sarcasms; whilst the queen and princesses were the constant objects of her ridicule. Inspired by the most diabolical sentiments, she put on the mask of religion to effect her purpose, and by her feigned devotion deceived the most clear-sighted. Whilst her thoughts were employed in forming plans of the blackest treason, she frequented the churches, made one in the different processions, went on pilgrimages, and practised all the external forms of religion with the greatest ostentation. Her confessor, father Malagrida, was an Italian Jesuit, sent by the general of the society on a mission to Portugal. Zealous, eloquent, and enthusiastic, he presently became the most fashionable spiritual director: people of every description made choice of him for their confessor: he was regarded as a saint, and consulted as an oracle. More than two hundred and fifty persons of consequence were concerned in this conspiracy, and nothing now seemed wanting but to fix the day for putting their design into execution.
