Strength=orpheus was an amazing great that he could tame some of the wildest beast.

weakness:his great love for EURYDICE.he went to huge lengths to bring her back to life.but when her death became definite he never played mudic again
Orpheus' greatest strength is his extraordinarily powerful and irresistible music. Anybody who hears his music shall obey and give what he ask for. His music can turn inanimate objects to live and animate ones. His music is absolutely powerful even against a God. On the other hand, his weakness is his dead wife , his love for her and his depression upon the untimely demise of Eurydice.
