Matthäus von Collin was an influential gentleman in the Vienna of the early 19th century. Tutor of Napoleon's son, professor of History and Philosophy at the University, host of an important cultural salon, part-time poet and friends with Josef von Spaun. We're especially interested in those last three aspects because Collin was one of those middled-aged gentlemen who, after Spaun had introduced them, befriended Schubert, welcomed him to his household, spread his music and introduced him to other influential people. Unfortunately, this relationship didn't last very long because Collin died in 1824, at forty-five; at least, it resulted in five Lieder, one of which we heard a while ago: the beautiful Nacht und Träume, composed after the poet's death.
