Ivan Andreyevich Krylov (Russian: Ива́н Андре́евич Крыло́в) was Russia's best-known fabulist and probably the most epigrammatic of all Russian authors. Formerly a dramatist and journalist, he only discovered his true genre at the age of 40. While many of his earlier fables were loosely based on Aesop's and La Fontaine's, later fables were original work, often with a satirical bent.
