Gessoed boards were used for writing notes or school exercises. Like the slate writing tablets of yesteryear, they could be used repeatedly, with old texts being whitewashed to provide a “clean slate” for another. This board still bears traces of earlier writing (at left). The main text is a wordy model letter that the student copied—and surely also was expected to memorize. His many spelling mistakes have been corrected in red ink by the teacher.
