Le festin d'Ésope (Aesop's Feast), Op. 39 No. 12, is a piano étude by Charles-Valentin Alkan. It is the final étude in the set (Twelve studies in all minor keys), Op. 39, published in 1857 (although it may have been written during the previous decade). It is a work of twenty-five variations based on an original theme and is in E minor. The technical skills required in the variations are a summation of the preceding études.
