Occasional poetry included important genres of Gdańsk literature. The development of the poetry climaxed in the 17th century when Gdańsk experienced rapid growth in the field of science, culture and economy. Johann Peter Titz (1619–1689) was a professor of rhetoric at the Academic Gymnasium in Gdańsk and one of the most prolific authors of occasional poetry. Besides writing poems for the occasion, Titz was often himself a formal addressee of the poems. The events in Titz’s life became the subjects of a number of epithalamiums, epitaphs and gratulatory poems written by Titz’s friends including students and professors of the Academic Gymnasium in Gdańsk (Samuel Schelwig (1643–1715), Christoph Behr (1642–1704), Friedrich Büthner (1622–1701) and the members of the patriciate in Gdańsk (Johann Ernst Schmieden (1626–1707), Constantin Freder (1643–1707). The article provides a preliminary analysis of the occasional poetry composed for Titz and the register of the poems that have survived in the holdings of the PAS Gdańsk Library.
