The volume contains the papers given at a conference held in Basle in Autumn 2006 on the writer Philipp von Zesen (1619-1689). The publication – the first collected volume devoted to this author for 35 years – displays the whole breadth of Zesen's work: Apart from his lyric poetry and novels, the papers discuss his linguistic and poetological innovations together with his contributions to nature philosophy, mythology, historiology and politics.
