Left, brown bell tent, apex not shown, patterned roof edge decoration, door flap fringe in light coloured material, walls appear to have a patterning. 

Right, golden ball apex, roof has gold shapes on a red background with a wreath encircling the middle of the roof, a similar wreath decorates the roof edge, the walls are decorated in a light colouring in a floral pattern on a dark brown background. 

Centre, only the top of the roof is visible, golden ball apex, similar in pattern or roof to bell tent on the right but on a darker back ground.

The painting probably decorated a wooden chest or a private furniture. The scene illustrates a biblical subject, the magnificent banquet offered by Ahusuerus, king of Persia. The painter really portrayed here a Renaissance feast, placed in the court of a Florentine patrician palace, where every detail is descripted: hostes sitting at the table, busy servants, the arrangement of the silver on the right and the splendid elegance of dresses and tapestries.”
