The moonlight of Tyszkiewicz is sunlight to the episcopate of Vilnius, that rose happily greeting the panegyric from Vilnius University of the Society of Jesus.

Full title: "LVX LVNÆ TYSZKIEVICIANÆ SICVT LVX SOLIS VILNENSI EPISCOPATVI Felicissime exorta Gratulatoria Panegyri Ex VOTO ALMAE Vniuersitatis Vilnensis Soc. Iesv / PER Constantinum Drucki Horski Dapiferiden Poloc. Philos. IV. Audit. repræsentata".

The Moonlight of Tyszkiewicz is Sunlight is a panegyric written by Vilnius University philosophy student Constantine Drucki Horsk to celebrate Jerzy Tyszkiewicz (1596–1656) being elected Bishop of Vilnius (1649). By employing the key components of the Tyszkiewicz Leliwa coat of arms (the moon and stars) the author creates various poetic connections with antique literature, history, and mythology. The books is valuable not only for its texts, but also for its illustrations, namely the two engravings by Daniel Pelzeldt. The first depicts a panoramic view of Vilnius and the Tyszkiewicz coat of arms, a half moon and star, which links the picture nicely with the first words of the panegyric. The engraving on the last page depicts a Jesuit horseman wielding a sword over Vilnius - an allusion to the fact that Vilnius is under the care of the Jesuits.
