Type of Spiritual Experience
"The Physiologus is a didactic text written or compiled in Greek by an unknown author, in Alexandria; its composition has been traditionally dated to the 2nd century AD by readers who saw parallels with writings of Clement of Alexandria, who is asserted to have known the text, though Alan Scott has made a case for a date at the end of the 3rd or in the 4th century. The Physiologus consists of descriptions of animals, birds, and fantastic creatures, sometimes stones and plants, provided with moral content. Each animal is described, and an anecdote follows, from which the moral and symbolic qualities of the animal are derived. Manuscripts are often, but not always, given illustrations, often lavish.
The book was translated into Latin in about 700, and into Ethiopic and Syriac, then into many European and Middle-Eastern languages, and many illuminated manuscript copies such as the Bern Physiologus survive. It retained its influence over ideas of the "meaning" of animals in Europe for over a thousand years. It was a predecessor of bestiaries (books of beasts). Medieval poetical literature is full of allusions that can be traced to the Physiologus tradition; the text also exerted great influence on the symbolism of medieval ecclesiastical art: symbols like those of the phoenix rising from its ashes and the pelican feeding her young with her own blood are still well-known.
A description of the experience
One version of the Latin text of the Physiologus reads:
"There is a monster in the sea which in Greek is called aspidochelone, in Latin "asp-turtle"; it is a great whale, that has what appear to be beaches on its hide, like those from the sea-shore. This creature raises its back above the waves of the sea, so that sailors believe that it is just an island, so that when they see it, it appears to them to be a sandy beach such as is common along the sea-shore. Believing it to be an island, they beach their ship alongside it, and disembarking, they plant stakes and tie up the ships. Then, in order to cook a meal after this work, they make fires on the sand as if on land. But when the monster feels the heat of these fires, it immediately submerges into the water, and pulls the ship into the depths of the sea.
