Rudolf Erich Raspe: Gulliver revived, London 1786 (R5)
Our first object was to learn what part of the world we were in; this we were for some time at a loss to ascertain: at last, I found, from former observations, that we were in the Caspian Sea! which washes part of the country of the Calmuck Tartars. How we came here, it was impossible to conceive, as this sea has no communication with any other. One of the tall people of the Cheese Island, whom I had brought with me, accounted for it thus; that the monster, in whose stomach we had been so long confined, had carried us here through some subterraneous passage; however, we pushed to shore; and I was the first who landed.
