This piece was made to tell the tale of Mercury plotting to take Lo. On the right side sits Mercury with an instrument on the left stands Argus and in the back is Lo. Lo was a Nymph and Zeus' lover. Hera ,Zeus' wife, was jealous and turned Lo into a cow and had Argus watch her so Zeus could not have contact. Mercury ,Zeus' messenger, lulls Argus to sleep kills him and takes Lo. Quellinus uses texture by carving more deeply and more detailed for the important characters and less detailed for the scenery in the background.
