Argus is a figure from Greek mythology known for his many eyes. He was a giant tasked with guarding Io, a priestess of Hera, to prevent her from being pursued by Zeus. Argus is often depicted as having a hundred eyes, which allowed him to keep watch even while some of his eyes slept. In addition to mythology, the name "Argus" is used in various contexts, such as in astronomy, where it refers to a constellation in the southern sky. It is also associated with technology, like the Argus surveillance system, which is designed for monitoring and security purposes.
