Description
In the school room space, Dorian recognizes this piece of furniture as something he would hide himself inside as a child (a literal type of closeting in the text). It is described as having "fantastically painted panels" with "tarnished gilt mouldings" (Wilde 118) suggesting that it is fairly old and disused. Like much of Dorian's attic room furniture the piece seems to be more Renaissance or Gothic in style.

The Met attributes this cassone to the workshop of mid 15th century Florentine artist Apollonio di Giovanni di Tomaso. It is described as being made of poplar wood, linen, polychromed and gilded gesso, and panels painted in tempera and gold. Though this may not be the exact piece referenced in Wilde's text, the painting and gilding of the piece are similar to what Dorian keeps in his schoolroom.
