Leo is one of the most beautiful constellations in the sky from a visual point of view. Its grouping of bright stars provides an outline of the mythical Nemean lion, which Hercules destroyed as one of his twelve labours. The delineation is unmistakeable; Leo is a lion that appears to be taking his ease, lying contentedly in the spring sky like the Sphinx near the pyramids of Egypt. His mane and head are distinguished by a train of stars that resembles a question mark in a reversed position, or a "sickle" shape, whilst its body and tail are well marked with familiar stars, of which Denebola is the brightest star in the tail.
