Mercure and Argus 

"Mercure and Argus" is a red chalk drawing by the Flemish artist Claes Moeyaert. The drawing depicts the Greek myth of Mercury, the messenger of the gods, killing the hundred-eyed giant Argus, who had been assigned to guard the nymph Io, whom Zeus had transformed into a cow. This drawing, currently housed in the Städel Museum, exemplifies Moeyaert's masterful use of line and shading to create a sense of depth and movement. It is a captivating example of his artistic skill and a testament to his understanding of classical mythology.
