Perhaps the Oldest Science Fiction story from the ancient world : preserved to the modern day. In 'True Histories' ("Trips to the Moon") the main character travels to a weird continent where almost anything is possible. During his travels there he visits the moon (the main subject of True Stories aka Trips to the moon). Other things happened also. At a certain moment he finds himself in the belly of a whale. These comical absurdities are described with the accuracy of a traveling guide. (Amazon)
Lucian of Samosata,(c. 125 – after 180) was a Hellenized Syrian satirist, rhetorician and pamphleteer who is best known for his characteristic tongue-in-cheek style, with which he frequently ridiculed superstition, religious practices, and belief in the paranormal. Although his native language was probably Syriac, all of his extant works are written entirely in ancient Greek.
