Meanwhile, I humbly ask Your Most Reverend Majesty to look upon this work of Harmony original: Harmonices, referring to the title of the book Harmonices Mundi, dedicated to your Name, with a serene countenance, and to consider this expression of my most devoted affection toward you as just and good. Indeed, may you delight your royal mind in the contemplation of the Works of God, as much as the necessary occupations of the Kingdom permit.
