In offering to the public the first complete biography yet attempted of the painter Overbeck, I wish to give a few words in explanation. The task has been far from easy: the materials, though the reverse of scanty, are scattered: reminiscences of the artist and criticisms on his works lie as fragments dispersed over the current literature of Germany. My endeavour has been to fill in vacuities, to thread together a consistent and connected narrative, and thus, so far as I have been able, to present a true and lucid history.
