Phoenix theophrasti ancient Greek ‘father of botany,’ had described several types of palms, including one from Crete. Apart from the usually inedible dates and upright fruit clusters, the Cretan species can appear quite similar to the cultivated date ("Phoenix dactylifera").

In Renaissance times the fable was taken up by the compilers of emblem books, starting with the originator of this genre, Andrea Alciato.
