In Greek and Roman mythology and religion, Sirius (SEE-ree-əss; Ancient Greek: Σείριος, Seírios, 'scorching') is the god and personification of the star Sirius, also known as the Dog Star, the brightest star in the night sky and the most prominent star in the constellation of Canis Major (or the Greater Dog). In ancient Greek and Roman texts, Sirius is portrayed as the scorching bringer of the summer heatwaves, the bright star who intensifies the Sun's own heat.
