This accomplished, amiable, and talented lady was cut off in the flower of her life, August 29th, 1665, by poison, administered by one of her own maids, instigated, as is supposed, by some jealous young artists. Her melancholy death was bewailed with demonstrations of public sorrow, and her remains were interred with great pomp and solemnity in the church of S. Domenico, in the same vault where reposed the ashes of Guido.
