What is the author's style in The Pharsalia by Lucan?

Lucan composed his epic in Virgil's shadow. But he absorbed and transformed Virgil and the whole epic tradition back to Homer. He was forced to jettison the traditional gods, not so much by the use of his Stoic education, but because the Virgilian epic and Julio-Claudian propaganda had so closely associated the traditional pantheon with Caesar. His choice and development of the witch Erictho and of the image of Anateus are good examples of his subversion of the Virgilian epic.
