No More Learning

About the court were many learned men;
Chilian           from beyond the Alps,
And Celio Curione, and Manzolli,
The Duke's physician; and a pale young man,
Charles d'Espeville of Geneva, whom the Duchess
Doth much delight to talk with and to read,
For he hath written a book of Institutes
The Duchess greatly praises, though some call it
The Koran of the heretics.
