Aesop's Fables, or the Aesopica, is a collection of fables credited to Aesop, a slave and storyteller believed to have lived in ancient Greece between 620 and 564 BCE. Of diverse origins, the stories associated with his name have descended to modern times through a number of sources and continue to be reinterpreted in different verbal registers and in popular as well as artistic media.

The fables originally belonged to the oral tradition and were not collected for some three centuries after Aesop's death. By that time, a variety of other stories, jokes and proverbs were being ascribed to him, although some of that material was from sources earlier than him or came from beyond the Greek cultural sphere. The process of inclusion has continued until the present, with some of the fables unrecorded before the Late Middle Ages and others arriving from outside Europe. The process is continuous and new stories are still being added to the Aesop corpus, even when they are demonstrably more recent work and sometimes from known authors.

Manuscripts in Latin and Greek were important avenues of transmission, although poetical treatments in European vernaculars eventually formed another. On the arrival of printing, collections of Aesop's fables were among the earliest books in a variety of languages. Through the means of later collections, and translations or adaptations of them, Aesop's reputation as a fabulist was transmitted throughout the world.

Initially the fables were addressed to adults and covered religious, social and political themes. They were also put to use as ethical guides and from the Renaissance onwards were particularly used for the education of children. Their ethical dimension was reinforced in the adult world through depiction in sculpture, painting and other illustrative means, as well as adaptation to drama and song. In addition, there have been reinterpretations of the meaning of fables and changes in emphasis over time.

William Caxton (c. 1422 – c. 1491) was an English merchant, diplomat, and writer. He is thought to be the first person to introduce a printing press into England, in 1476, and as a printer was the first English retailer of printed books.

Neither his parentage nor date of birth is known for certain, but he may have been born between 1415 and 1424, perhaps in the Weald or wood land of Kent, perhaps in Hadlow or Tenterden. In 1438 he was apprenticed to Robert Large, a wealthy London silk mercer.

Shortly after Large's death, Caxton moved to Bruges, Belgium, a wealthy cultured city, where he was settled by 1450. Successful in business, he became governor of the Company of Merchant Adventurers of London; on his business travels, he observed the new printing industry in Cologne, which led him to start a printing press in Bruges in collaboration with Colard Mansion. When Margaret of York, sister of Edward IV, married the Duke of Burgundy, they moved to Bruges and befriended Caxton. It was the Duchess who encouraged Caxton to complete his translation of the Recuyell of the Historyes of Troye, a collection of stories associated with Homer's Iliad, which he did in 1471.

On his return to England, heavy demand for his translation prompted Caxton to set up a press at Westminster in 1476. Although the first book he is known to have produced was an edition of Chaucer's The Canterbury Tales, he went on to publish chivalric romances, classical works, and English and Roman histories, and to edit many others. He was the first to translate Aesop's Fables in 1484. Caxton was not an adequate translator, and under pressure to publish as much as possible as quickly as possible, he sometimes simply transferred French words into English; but because of the success of his translations, he is credited with helping to promote the Chancery English he used to the status of standard dialect throughout England.

In 2002, Caxton was named among the 100 Greatest Britons in a BBC poll.
