And Poseidon himself set in order [...] the central island, bringing up from beneath the earth two springs of waters, the one flowing warm from its source, the other cold, and producing out of the earth all kinds of food in plenty. [Crit. 113e].
One of the signal characteristics of Plato's Atlantis is this existence of two springs bearing warm and cold water on its central acropolis. These are described in the Critias [117ab] as being: -
[O]f abundant volume, and each kind was wonderfully well adapted for use because of the natural taste and excellence of its waters; and these they surrounded with buildings and with plantations of trees such as suited the waters; and, moreover, they set reservoirs round about, some under the open sky, and others under cover to supply hot baths in the winter; they put separate baths for the kings and for the private citizens, besides others for women, and others again for horses and all other beasts of burden, fitting out each in an appropriate manner. And the outflowing water they conducted to the sacred grove of Poseidon, which contained trees of all kinds that were of marvellous beauty and height because of the richness of the soil; and by means of channels they led the water to the outer circles over against the bridges.
The purpose of this essay is to provide an overview of the motif of springs - especially twin hot and cold springs - and other bodies of water in Greek mythology.
The most obvious literary source for the springs in Atlantis is Homer's Iliad, which provides a brief description of two springs near the walls of the famous Troy [22.145-156]: -
Passing the lookout point, and the wind-swept wild fig tree, along the cart-track they ran leaving the wall behind, and came to two lovely springs where the waters rise to feed the eddying Scamander. One flows warm, and steam rises above it as smoke from a fire, while even in summer the other is ice-water, cold as freezing snow or hail. Nearby are the fine wide troughs of stone where the wives and daughters of the Trojans once washed their gleaming clothes in peace-time, before the advent of the Greeks.
Here we have the same configuration as those in Atlantis, albeit they are just outside Troy's walls, whereas the springs in Atlantis are at the very centre of the city on the acropolis. Homeric influence may also be behind the numbering of the fleet of Atlantis, said to be formed of 1,200 vessels [Crit. 119b], which accords well with the Greek force from the "Catalogue of Ships" [Iliad 2.494-759], which numbers 1,185. Herodotus, too, may have been influenced by the Iliad in his according the Persian armada a strength of 1,207 ships [7.89].
In terms of precursors for the idea of twin springs (though without any difference in temperature), we find twin springs within the garden of the Phaeacian king Alcinous in Homer's Odyssey [7.129-131]. Here, "there are two springs in the orchard, one flowing through the whole garden, while the other runs the opposite way, under the courtyard sill, near where the people of the city draw their water, towards the great house," with another spring noted in a grove sacred to Athena nearby [6.292-294]. Coincidentally, the name of the Phaeacians' former home of Hypereia is also the name of a spring in Thessaly mentioned in the Iliad, where it is on one occasion paired with a second spring, Messeïs [6.457], while Hypereia is placed within the land ruled by Euaemon, alongside "Asterium and the white towers of Titanus" [2.734-737].
The spring in found in the grove of Athena, which is made up of poplar trees, which also appear in other descriptions of sources of water from the Odyssey: poplars stand around a cave from which a stream emerges on the small island facing the harbour on the island of the Cyclopes [9.141-143] and poplars are one of the species forming the woodland around the cave inhabited by Calypso on Ogygia [5.64], close to which "four neighbouring springs, channelled this way and that, flowed with crystal water" [5.70], as well as appearing at the edge of the island where they "rose to the sky" [5.239], reminiscent of the "trees of all kinds that were of marvellous beauty and height because of the richness of the soil" in the sacred grove of Poseidon on the Atlantean acropolis [Crit. 117b]. The water management and tree plantations noted in the Critias [117ab] bear a strong resemblance to the descriptions of Ogygia and Scheria in the Odyssey.
Additionally, perhaps one of the most obvious sources for the difference in the temperatures for the springs on the Atlantean acropolis can also be found in Homer's description of Odysseus in the land of the dead beyond Oceanus [10.513-514], where he comes to: -
[A] rock where two roaring rivers join the Acheron, Cocytus, which is a tributary of the Styx, and Pyriphlegethon.
As the name suggests, the Pyriphlegethon was, in stark contrast to its gloomy underworld peers, envisaged as being a river of flame. Plato pairs it with the Cocytus in the Phaedo [113c], where the Pyriphlegethon forms a lake of mud and water similar in some respects to the shallow and muddy nature of the Atlantic as a result of the sinking of the island.
Moreover, Croatian classicist Tomislav Bilić notes two further occurrences of juxtaposed hot and cold bodies of water, both of which postdate Plato. In his biography of the religious figure Apollonius of Tyana [1.6], Philostratus makes mention of the Asbama, a spring near Apollonius' home town, the temperature of which is dependent upon the character of the one who would slake his thirst with its waters: -
Now there is near Tyana a well sacred to Zeus, the god of paths, so they say, and they call it the well of Asbama. Here a spring rises cold, but bubbles up like a boiling cauldron. This water is favorable and sweet to those who keep their paths, but to perjurers it brings hot-footed justice; for it attacks their eyes and hands and feet, and they fall the prey of dropsy and wasting disease; and they are not even able to go away, but are held on the spot and bemoan themselves at the edge of the spring, acknowledging their perjuries.
Towards the end of antiquity, Priscianus speaks about a sacred fountain associated with Cadmus and Harmonia's exile in Illyria, which Bilić suspects "has a complex mythical background and belongs properly to some early concept of the Adriatic as the Land of Bliss," adding portentiously that "the abode of the serpentine hero from Thebes seems to be located in the West, which is a close parallel with the western abode of serpentine Typhon, Ophion, or Cronus himself." The "Sacred fountain, at the same time unnaturally cold and miraculously hot" would then be properly located in the furthest west. As Bilić notes elsewhere: "[a]mong the earliest accounts of the western exile is presumably Cronus' banishment to the Adriatic. It could be claimed that Cronus and Rhea were associated with the Adriatic in an age when the Greeks considered it the western edge of the known world, this being the earliest layer of their mythical geography."
A later conception of the "land of bliss" places it in the furthest west, where the Roman writer Pomponius Mela mentions two springs possessed of strange and miraculous powers on the Fortunate Isles, which, in this instance, appear in his text to signify the Canary Islands [3.102]. The section is worth quoting in full: -
Opposite the sandy part, the Fortunate Isles abound in spontaneously generated plants; and with various ones always producing new fruit in rapid succession, the islands nourish people who want for nothing, and whose islands are more blissfully productive than others are. One of the islands is primarily famous for the uniqueness of its two springs: those who have sipped the one laugh to death; the cure for those so affected is to drink from the other.
Significantly, we have here a paradise in the Atlantic, whose "golden age"-like state (extreme fruitfulness providing ample foodstocks to the inhabitants) echoes Plato's description in the Critias [esp. 115ab; 118e].
This passage also bears similarities to Theopompus' two rivers of the western extreme of the outer continent in the Meropis: -
[T]here are two rivers in this place, one of pleasure, the other of grief; and that along each river grow trees of the bigness of a plane-tree. Those which grow up by the river of grief bear fruit of this nature; if any one eat of them, he shall spend all the rest of his life in tears and grief, and so die. The other trees which grow by the river of pleasure produce fruit of a contrary nature, for who tastes thereof shall be eased from all his former desires: if he loved any thing, he shall quite forget it; and in a short time shall become younger, and live over again his former years: he shall cast off old age, and return to the prime of his strength, becoming first a young man, then a child, lastly, an infant, and so die.
This duality reflects the dual nature of the two major cities of the continent as described by Theopomus: warlike Machimus and lawful Eusebes.
In the real world, Pausanias discusses the opposite natures of two Arcadian rivers, the Styx (whose implications are self-explanatory, given that this stream shares its name with the dread river of the underworld) [8.17.6-18.6] and the Alyssus, which reportedly possessed curative powers [8.19.2-3] and ran near a complex of medical baths based around a cave dedicated to Artemis Hemerasia [8.18.7-8].
Bilić also notes "Orphic" sources: -
According to the 'Orphic' Gold Leaves, there are two springs in Hades: first, the one on the left hand side with a white cypress growing beside it, which is to be avoided; and a second, called the fountain of Mnemosyne, whose cool water the initiates should drink.
Mnemosyne is the fountain of remembrance and is thus clearly drawn into opposition with the fountain of Lethe, mentioned by Plato in the "Myth of Er" [Republic 10.621a], which causes the souls of the deceased to forget their past lives during the process of metempsychosis.
Plutarch, in the De sera numinis vindicta , which is probably modelled on the Er myth, describes the underworld journey of one Thespesius of Soli, in which he encounters demons surrounding three pools: -
Moreover, he said, there were certain lakes that lay parallel and equidistant one from the other, the one of boiling gold, another of lead, exceeding cold, and the third of iron, which was very scaly and rugged.
It is also worth pointing out that, in Egyptian cosmology, the Nile emerged from the boundless waters of the Nun via two qrtj ("caves") on the island of Elephantine (a.k.a. Abu or Yebu). Jan Assmann associates the inundation, which has its origins in the cave, with the efflux of Osiris after his murder by Seth, with the Elephantine region associated with Osiris' wounded leg. E.A. Wallis Budge associated Elephantine with Kns.t, a location which is nowadays normally placed in Nubia which is mentioned in the Pyramid Texts [Unas 254.280] in terms reminiscent of the great meeting of the archons of Atlantis: -
Ha! Your fields are in fright, o jAd-star,
before the pillar of stars,
when they have seen the pillar of Kenset (a country), the Bull of Heaven.
How the herdsman of the bulls is overwhelmed with awe before him!
The existence of a warm spring has been interpreted as possible evidence that Atlantis was volcanic, and thus probably met its demise in a volcanic event. Against this, however, it should be noted that Plato never specifically mentions volcanic action as the mechanism for the destruction of Atlantis (though, of course, he never provided a fully-detailed account of the island's destruction). For Plato's thinking on volcanoes, see the Phaedo [113b].
It must also be noted that hot springs are not necessarily a sign of volcanism: there are a number in the United Kingdom, which is not currently located on a tectonic hot zone.
The hot and cold springs have also been put forward as support for the Minoan hypothesis as warm and cold water channels have been excavated on the island of Thera. However, the likelihood that the Atlantis myth represents a memory of Minoan Crete and the Thera eruption is to be rejected on numerous other grounds.
