Allegorical interpretations of Plato
Many interpreters of Plato held that his writings contain passages with double meanings, called allegories, symbols, or myths, that give the dialogues layers of figurative meaning in addition to their usual literal meaning. These allegorical interpretations of Plato were dominant for more than fifteen hundred years, from about the 1st century CE through the Renaissance and into the 18th century, and were advocated by major Platonist philosophers such as Plotinus, Porphyry, Syrianus, Proclus, and Marsilio Ficino.
