The Panchatantra is an ancient Sanskrit collection of stories, probably first composed around 300 CE (give or take a century or two), though some of its component stories may be much older. The original text is not extant, but the work has been widely revised and translated such that there exist "over 200 versions in more than 50 languages." The actual content of these versions sometimes differs greatly. The lists of stories in a few notable versions are compared below.
