257 years ago today, February 13, 1768 (December 25, 1767 lunar calendar), the birthday of the famous Russian writer Krylov. Krylov's full name is Ivan Andreevich Krylov (1768-1844), a famous Russian allegorist. Born in a poor family of infantry captains in Moscow, he was a journalist, editor of satirical publications such as "Morning" and "Elf Post", and wrote many satirical literature. At the same time, he also wrote a number of satirical dramas "Crazy Family" and "Pranksters". But his main achievement is still due to his writing 206 fables. In 1819, at the age of 50, Krylov was determined to learn ancient Greek in order to be able to read the original poems of the ancient Greek poet Homer and Aesop's fables. Friends advised him: "It is very difficult to learn a foreign language at the age of fifty." He said: "As long as you have determination and perseverance, it is never too late to learn it at any time." Two years later, he mastered ancient Greek proficiently and read the original text of Aesop's fables fluently, which amazed his friend and expert in ancient Greek, Gneditch. After 1806, he dedicated himself to fables. Published 9 volumes of "Krylov's Fables", a total of 206 articles. Krylov's fables are all about birds, insects, fish, animals, landscapes, flowers and plants, but they all express realistic content, so they are very infectious to readers. Another characteristic of Krylov's fables is that his language is simple, humorous, funny and attractive, and he absorbs a lot of folk proverbs and sayings to make the articles seem popular, vivid and intimate. Now his fables have been translated into dozens of languages and published all over the world.
