Among the clues to the figures' associations are a selection of scientific instruments including two globes (one terrestrial and one celestial), a shepherd's dial, a quadrant, a torquetum, and a polyhedral sundial, as well as various textiles including the floor mosaic, based on a design from Westminster Abbey (the Cosmati pavement, before the High Altar), and the carpet on the upper shelf, an example of Oriental carpets in Renaissance painting. The figure on the left is in secular attire while the figure on the right is dressed in clerical clothes. They flank the table, which displays open books and symbols of religious knowledge, including a symbolic link to the Virgin.
