"Friends know each other in trouble" - this catchphrase belongs to the "father of fables" Aesop.
2600 years ago, the slave Aesop created more than 400 fables. All this time they were retold by word of mouth, and thus we have about 100 works. The most recent retelling of Aesop's fables for this book was performed by a real storyteller, "Ukrainian nightingale" Alexander Vizhenko. He retold 35 fables!
Aesop's works were studied by children in the time of Aristophanes in Athens. Much has changed since then, but human vices have remained the same. Why? Maybe because no one read Aesop's fables to many people as children? ;-) This collection can be a "vaccine" against greed, laziness, haste, ingratitude and other shortcomings. The power of Aesop's fables is not in the instructive conclusions, but in the "Aesopian language", allegorical images of animals: The wolf embodies cruelty, the Fox - cunning, the Eagle - nobility, and so on. It is in this form that the idea becomes clear to the child.
