Leonora, a celebrated singer and composer, was born at Naples, but spent the greater part of her life at Rome. She was daughter of Adriana Baroni di Mantua, baroness of Piancavetta, a lady also distinguished for her musical talents, and, on account of her beauty, surnamed the Fair. A collection of verses in her honour was published in 1623, under the title of Teatro della gloria D'Adriana. Leonora, like her mother, was celebrated by the wits; and in 1639 there was published a collection of poems in various languages addressed to her, under the title of Apollinis Poetici alle Glorie della Signora Leonora Baroni. Among the Latin poems of Milton are no fewer than three, entitled Ad Leonoram Roma Cenaculum, of which this lady is the subject.
