The Phaiakes deliver Odysseus to his home island, Ithake, leaving him asleep on the shore. When he wakes up, he hides their gifts to him in a nearby cave:
At the head of the harbour is a long-leafed olive tree;
and near it, a cave, lovely and shaded,
sacred to Nymphs, who are called Naiads.
In it there are jars and amphoras
of stone; and bees store honey in them.
And there are stone looms, long, where Nymphs
weave cloths of shimmering sea-dye, a wonder to see;
and ever-flowing waters. And there are two entrances.
The one to the north is where humans gain access,
the one to the south is more divine: not that way
do men enter — that is the path for immortals.
The Neoplatonist philosopher Porphyry famously wrote an essay on this passage, interpreting it in allegorical terms (Lamberton 1983). There’s no good reason to think it’s a real cave: even Porphyry reports that no ancient geographical writer could identify it. And the Odyssey’s sense of geography is unrealistic at the best of times.
Real caves
That hasn’t stopped the modern trend for identifying real places as the setting for scenes in the Odyssey. Fans have identified the cave of the Nymphs with multiple real caves: Loizos’ Cave, at Polis Beach; Marmarospilia (‘marble cave’), near Vathi; and Lake Melissani on Kefalonia.
Ancient people left religious votive offerings in these caves, dedicated to a range of divinities, and in a few late cases they seem to have done so under the influence of the Odyssey. But that was centuries later. It doesn’t mean the Odyssey itself is thinking of realist landscapes: as we saw in looking at the wanderings, the Odyssey’s idea of prehistory is related to reality, but it’s a fictional alternate prehistoric reality.
Still, here are a few more details on these candidates.

Loizos’ Cave was destroyed by the 1953 earthquake, but in the 1930s it had been surveyed by the British School at Athens. This cave did have older votive offerings, some Iron Age, and a few from the Bronze Age. Where it’s possible to identify the divinities that votive offerings are dedicated to, they’re mostly Olympian gods, especially Hera and Artemis. Finds relating to nymphs or Odysseus are late: there are some Hellenistic-era nymph reliefs; and, among a hundred-odd clay masks found in the cave, there’s one mask of a female face, dating to the 2nd/1st century BCE, with ‘prayer to Odysseus’ written on the back. These don’t suggest the Odyssey had this cave in mind in the 7th century BCE: they suggest people in the Roman era were influenced by Homer. The main attraction of this cave as a candidate actually lies in twelve 9th century BCE bronze cauldrons, though they aren’t specific to any divinity, and the context suggests that if they were dedicated to a specific divinity it would most likely be Hera. See further Antonaccio 1995: 152–155. Note that some finds were apparently stolen by Schliemann, who visited the cave in the 1860s, and are presumably lost forever.

Marmarospilia (‘marble cave’) is signposted locally as ‘Cave of Nymphs’ (Σπήλαιο Νυμφών), with UNESCO endorsement — in spite of the fact that it’s 190 metres above sea level, more than a kilometre from the head of the bay where Vathi is located, and the entrance faces away from the bay. It is widely claimed — falsely — that there used to be a second entrance downhill by the bay: that’s wishful thinking, trying to make it sound more like the cave in Odyssey 13. In reality the cave extends about 25 m into the hillside, sloping upwards to the east. The identification with the Odyssey’s cave was proposed by Anna Petroheilou in 1971. The cave is normally closed because of damage done by archaeological excavations in 1998–2002, which left the cave unsafe, and reportedly destroyed many of the cave’s speleothems.

Melissani is actually an underground lake in a sinkhole, which was exposed when the roof collapsed in the 1953 earthquake. No scholars have identified it with Odysseus’ Nymph cave (so far as I know), but some tourism materials do, probably because it is extremely colourful with the roof gone. A cave on Kefalonia is under consideration thanks to the theory that ‘Homer’s Ithake’ shouldn’t be identified with modern Ithaki but with the Paliki peninsula of western Kefalonia (though Melissani is not on Paliki).
| The Paliki theory is associated with Spiridon Marinatos and Robert Bittlestone. It’s motivated by two false assumptions: (1) Homer is always realist, and the job of modern researchers is to find the reality that corresponds to Homer; (2) geographical descriptions in the Odyssey are always rigorously accurate. Bittlestone, for reference, localises Odysseus’ cave at a hypothetical cave that he thinks must have once existed at Atheras Beach, which he calls ‘Phorcys Bay’ in anticipation of his own theory (Bittlestone 1998: 418–431). |
Homeric allegories
When Porphyry wrote his essay on the cave, there was already a long-standing tradition of interpreting Homer allegorically. Where some modern fans like to pretend everything in Homer is literally real, the ancient allegorists liked to treat the poems as encoded forms of hidden knowledge. Another notable work is Herakleitos’ Homeric problems (1st/2nd century CE), which sees all kinds of meteorological, psychological, and cosmogonic symbolism in Homer. But the tradition goes back centuries: way back in the 6th century BCE Theagenes of Rhegion was already interpreting Homer’s gods as metaphors for natural forces — Hera = air, Hephaistos = fire, and so on.
| Herakleitos: see Russell and Konstan 2005. Theagenes: schol. B on Iliad 20.67 (= Porphyry, Homeric questions on the Iliad ad 20.67–75 ed. MacPhail). |
In reality, the Odyssey is a fictional narrative designed to be transparent. A sane reading shouldn’t be either realist or allegorical.
Having said that, there are cases of symbolism in Homer. But to do this legitimately, we have to explain Homer from Homer. If there’s symbolism, we find it by comparing how Homer operates in other contexts.
For example, hospitality is genuinely symbolic. It’s a cipher for virtue or vice. We know this because it’s a common pattern: a character’s behaviour in a hospitality type scene shows whether they are a good civilised person (they welcome guests into their home properly, they behave well when they visit others) or an uncivilised threat that has to be eliminated (they abuse their host or their guests). Homer uses formulaic scenes to send very specific ethical messages.
What about the cave? Is there legitimately any coded symbolism, whether or not it agrees with Porphyry’s analysis? Well, let’s review the physical features of the cave:
- located next to an olive tree at the head of a bay
- stone ‘jars’ and ‘amphoras’ that act as beehives
- stone ‘looms’ with colourful ‘cloths’
- running water
- two entrances, to north and south
We don’t need to imagine that this is realist in the sense of being a specific real cave on Ithaki; but individual features in isolation may be inspired by features that exist in real caves.
The text specifies that the Nymphs are Naiads: that implies that the running water is a freshwater spring. Some modern readers have reasonably interpreted the stone jars, amphoras, and looms as stalagmites or stalactites. That’s clearest in the case of the ‘looms’: the ‘cloths’ must surely be inspired by flowstone formations.

No symbolism so far: this is just the text’s direct meaning. I don’t see any clear signs of symbolism in the olive tree, the speleothems, the bees, or the spring.
But the two entrances, one for mortals and one for gods? That’s definitely symbolic. Because it fits into a pattern that appears elsewhere in Homer and in other Archaic poetry.
Dualities: mortal and immortal, real and unreal
The closest parallel for the cave’s two entrances is in Penelope’s account of how dreams work (Odyssey 19.560–569).
Stranger, dreams are stories impossible to work out,
and not all of them work out for humans.
For fleeting dreams have have two gates:
one is made of horn, and the other of ivory.
The ones that come through the sawn ivory,
those ones cheat you: their words are irrelephant.
But the ones that come through the door of sawn horns,
truth is deer to them, whenever someone sees one of them.
I do not think my strange dream came from there,
though it would be good news for me and my son if it did.
By the way, the wordplays aren’t jokes: in Greek, the ‘ivory’ (elephas) dreams are cheaters (elephairontai), and the ‘horn’ (keras) dreams accomplish things (krainousi). In early Greek literature, wordplay is word magic.
Poems, dreams, and oracles are regularly cast in terms of two types of knowledge: truth and falsehood, divine and mortal, day and night, reality and opinion. The divine knowledge of the Muses is real, while mortal knowledge is just rumour or kleos (Iliad 2.484–486). At the same time, the Muses know both how to say false things that sound real, and also how to declare the truth (Theogony 27–28). Apollo warns that mortals who rely on valid omen birds will do well, but those who trust in vain birds will achieve nothing (Hymn to Hermes 543–549).
Gates and doorways are a particularly vivid bit of imagery for the two types of knowledge. In Penelope’s account, and in the cave of the Nymphs, one door is reserved for the mortal and the unreal. The other is for truth, the divine, and the real.
Compare how Parmenides passes the gates of Night and Day on his journey along the ‘road of the divinity’, travelling the path of knowledge:
Hastening to guide me to the light
the daughters of the Sun left the house of Night,
lifting the veils from their faces with their hands.
Here are the gates of the paths of Night and Day:
they have a lintel, and a stone threshold,
and the gates of aither fill the great doorframe.
Justice, goddess of payment, holds the keys of exchange.Parmenides, On nature fr. B1.8–14
Rather than one gate for each type of knowledge, these gates are the barrier between day and night. Parmenides goes on to talk at length about the relationship between what is and what is not, and between truth and opinion. He does not name the goddess who instructs him in these things: the role of an oracle would typically be played by Night, as in the Derveni Theogony. When Justice allows him through the gates, it is ambiguous whether he is passing from day to night or from night to day; Hesiod, too, talks of Night and Day ‘exchanging’ as they pass the threshold of their house (Theogony 748–754).
Porphyry suggests that the mortal entrance to the cave of the Nymphs is for entering the cave, and the divine entrance for ‘those ascending to the gods’ (On the cave of the Nymphs 23). He singles out Parmenides, saying that Parmenides was thinking of Odysseus’ cave when he wrote about the gates of Night and Day. The symbolism is a bit more widespread than that. But Porphyry is certainly right in seeing that they’re related.
