In 1623, the property of Ladislaus Seydlitz von Schönfeld was confiscated and immediately purchased by Polyxena of Lobkowicz. It also included the Encovany estate with Seydlitz's library, the core of which was the book collection of the previous two lords at Encovany, the Vice- -Chancellor of the Kingdom of Bohemia Oswald Schönfeld von Schönfeld (1524-1589) and his son Rudolf (1565-1602).

The article provides the basic information not only on fragments of this Renaissance castle library but also on the fates of its first owners.
