In 1669 Perrault advised Louis XIV to include thirty-nine fountains each representing one of the fables of Aesop in the labyrinth of Versailles in the gardens of Versailles. The work was carried out between 1672 and 1677. Water jets spurting from the animals' mouths were conceived to give the impression of speech between the creatures. There was a plaque with a caption and a quatrain written by the poet Isaac de Benserade next to each fountain. Perrault produced the guidebook for the labyrinth, "Labyrinte de Versailles", printed at the royal press, Paris, in 1677, and illustrated by Sebastien le Clerc.
