published the Parnassus renovatus in praise of his mentor and patron, the eminent jurist Georg Schönborner (1579–1637). Later the same year Gryphius became the tutor of Schönborner's two sons, on Schönborner's estate near Freystadt, in Silesia (today, Kożuchów, Poland). A highly educated scholar, Schönborner held various government administrative posts and by that time had been honored by Emperor Ferdinand II with the title of Imperial Count Palatine (Hofpfalzgraf). On 30 November 1637, Schönborner recognized Gryphius's poetic talent by bestowing upon him the title of poeta laureatus and master of philosophy, as well as a patent of nobility (of which Gryphius, however, never made use). Schönborner died less than a month later, on 23 December 1637. While staying with Schönborner, Gryphius completed his first collection of poems, Sonnete ("Sonnets"), which was published in 1637 by Wigand Funck in Lissa (today Leszno, Poland), and is also known as the Lissaer Sonettbuch, after the town. The collection of 31 sonnets includes some of his best known poems, such as "Vanitas vanitatum, et omnia vanitas", later titled "Es ist alles eitel" (All is vanity), about the effects of war and the transitoriness of human life; "Menschliches Elende" (Human misery); and "Trawrklage des verwüsteten Deutschlandes" (Lament of devastated Germany). In 1632, he had witnessed the pillaging and burning of the Silesian town of Freystadt by Swedish troops, and immortalized the event in his poem Fewrige Freystadt. Also in 1637 he went to continue his studies at Leiden, where he remained for six years, both hearing and delivering lectures. Here he fell under the influence of the great Dutch dramatists, Pieter Corneliszoon Hooft and Joost van den Vondel, who largely determined the character of his later dramatic works. In 1635 with the Prager Frieden (Peace of Prague), the Habsburgs took control over in Silesia again and persecuted Protestants and closed their churches. In 1638 Paul Gryphius, the brother of Andreas, received a position as Superindendant at Crossen an der Oder (Krosno Odrzańskie) in Brandenburg from the Elector Georg Wilhelm of Brandenburg. Paul was for several years banned from Silesia for of being a Protestant, and Andreas dedicated and sent him several poems for the start of his new position. Travel and dramatic work After travelling in France, Italy and South Germany, Gryphius settled in 1647 at Fraustadt, where he began his dramatic work, and in 1650 was appointed syndic of Glogau, a post he held until
