Lucianus of Samosata lived in the second century A.D. He wrote many texts in Greek, of which more than eighty are still extant. One of these texts is his "True Histories", his "monument of lies". In it he asserts: "One thing I confidently pronounce for a truth, that I lie". But does he lie? For if he does, his assertion must be a lie and consequently he must be telling the truth... "True histories" consists of two books. This analysis of these books is mostly about the first book, which is about a voyage made to the Moon and back in Far Antiquity. This voyage in the author's opinion is credible and his interpretation reveals quite a bit about the space technology, and extraterrestrial civilization of the pagan gods, an earlier human species.
