Excerpt:

On one of the planets that orbits the star named Sirius there lived a spirited young man, who I had the honor of meeting on the last voyage he made to our little ant hill. He was called Micromegas , a fitting name for anyone so great. He was eight leagues tall, or 24,000 geometric paces of five feet each.

Certain geometers , always of use to the public, will immediately take up their pens, and will find that since Mr. Micromegas, inhabitant of the country of Sirius, is 24,000 paces tall, which is equivalent to 20,000 feet, and since we citizens of the earth are hardly five feet tall, and our sphere 9,000 leagues around; they will find, I say, that it is absolutely necessary that the sphere that produced him was 21,600,000 times greater in circumference than our little Earth. Nothing in nature is simpler or more orderly. The sovereign states of Germany or Italy, which one can traverse in a half hour, compared to the empires of Turkey, Moscow, or China, are only feeble reflections of the prodigious differences that nature has placed in all beings.

His excellency's size being as great as I have said, all our sculptors and all our painters will agree without protest that his belt would have been 50,000 feet around, which gives him very good proportions. His nose taking up one third of his attractive face, and his attractive face taking up one seventh of his attractive body, it must be admitted that the nose of the Sirian is 6,333 feet plus a fraction; which is manifest.

As for his mind, it is one of the most cultivated that we have. He knows many things. He invented some of them. He was not even 250 years old when he studied, as is customary, at the most celebrated colleges of his planet, where he managed to figure out by pure willpower more than 50 of Euclid's propositions. That makes 18 more than Blaise Pascal, who, after having figured out 32 while screwing around, according to his sister's reports, later became a fairly mediocre geometer and a very bad metaphysician. Towards his 450th year, near the end of his infancy, he dissected many small insects no more than 100 feet in diameter, which would evade ordinary microscopes. He wrote a very curious book about this, and it gave him some income. The mufti of his country, an extremely ignorant worrywart, found some suspicious, rash , disagreeable, and heretical propositions in the book, smelled heresy, and pursued it vigorously; it was a matter of finding out whether the substantial form of the fleas of Sirius were of the same nature as those of the snails. Micromegas gave a spirited defense; he brought in some women to testify in his favor; the trial lasted 220 years. Finally the mufti had the book condemned by jurisconsults who had not read it, and the author was ordered not to appear in court for 800 years .
