The Greek and Roman mythology abounds with data verifying the Solar character of the stories of the origin of civilisation and morals. Arts and manufactures are constantly brought into connexion with mythical names which are recognised by comparative philologists as designations of the Sun. Not only the musician but the smith of Olympus are Solar figures; so also the first navigator and founder of cities. The right understanding of Mythology was long hindered by the so-called Euhemeristic system, which assumed that the gods of mythology, and especially of the Greek and Roman mythology (for scarcely any others were sufficiently known to be considered), were only great benefactors of humanity, who after their death were rewarded by divine honours; and this system has been maintained till the present day. The Myth of Civilisation consequently had to be fitted into the frame of this convenient system. It was said that posterity had from mere _Gratitude_ raised the inventor of the arts to the throne of deity. Petrarch says, ‘We know that the founders of some arts after their death were rewarded by divine honours, rather from grateful than from pious feelings ... Thus Apollo was made a god through his lyre, Apollo and Aesculapius through medicine, Saturn, Liber and Ceres through agriculture, Vulcan through his smithy.’[549] This mode of regarding the subject was not only upheld from Euhemerus down to Petrarch, but exerted its influence on the interpretation of the ancient stories even to our own times.
