Lucian of Samosata was anything but a stodgy old classical Greek writer. In fact, he made a living making fun of stodgy old classical Greek writers; one can think of him as a very early stand-up comic. He knew that his listeners were familiar with Homer and the other great Greek authors, and he used the classics as fodder for irreverent freestyles that brought him fame (and money) all over the eastern Mediterranean.
One of his styles was what was known as "Menippean" satire, which involved parodying men, ideas, and other styles of writing, often all at once. He was a particular master of one sub-genre of this kind, the so-called "Dialogues with the Dead." Here, Lucian, like an ancient version of Father Guido Sarducci, made mock visits to dead celebrities and conducted farcical interviews with them (you can see something of this in his interview with Homer in Book II of The True History). Menippean satire has had, largely because of Lucian, a lasting influence on English fiction, from Chaucer to Swift to Carlyle; more recent practitioners include the Irish novelist Flann O'Brien and the American Thomas Pynchon.
But what Lucian excelled at was, in a word, sheer invention. While loudly proclaiming that everything in his story was false, he set out a "true history" that opened the floodgates of fantasy and science fiction long before those genres came into their modern existence.
You'll see Lucian's influence as well in the films of Terry Gilliam, especially in The Adventures of Baron Munchausen. The idea of a "King of the Moon" who rides on a three-headed vulture and casts asparagus-stalk spears is right out of the True History -- in part, this is Gilliam's fancy, but it's also because the original tales of Baron Münchausen penned by Raspé in the Eighteenth Century were richly plagiarized from other authors, Lucian chief among them.
So plunge in! Have fun! And remember, not a word of this is true!
