Did Ancient Greek Hero Odysseus Travel to Ireland?

Homer’s Odyssey tells the tale of Odysseus returning to his home after the Trojan War. For a variety of reasons, the trip is not an easy one. It takes him a full ten years to return home.

But the journey from Troy to Ithaca, Odysseus’ home island, should not have been too difficult and certainly not a ten-year trip. For this reason, some researchers have claimed that Odysseus actually traveled outside of the Mediterranean. There is even the suggestion that he traveled to Ireland.

Odysseus travel to Ogygia and its connection to Ireland

In the Odyssey, one of the places Odysseus visits is an island called Ogygia. This was the home of the nymph Calypso, who offers Odysseus immortality if he agrees to marry her. She refuses to let him leave otherwise. The gods intervene and force Calypso to release him. Hence, after seven years on the island, Odysseus builds a raft and sails away.

The location of Ogygia has been the subject of considerable speculation. According to Homer’s account, the island is a place of beautiful meadows, fountains, woods, and various types of birds. However, none of this is particularly helpful. All sorts of islands could fit this description.

In ancient times, various suggestions were made as to where Ogygia might actually be located. More recently, some scholars have argued that Ogygia is identical to Ireland. If this identification is correct, this would mean that Odysseus spent seven years in Ireland.

The most notable scholar to have come to this conclusion was Roderick O’Flaherty. In 1685, he used the name ‘Ogygia’ as a synonym for Ireland in the title of one of his books. It was called: Ogygia: Or a Chronological Account of Irish Events.

Plutarch’s account of Ogygia

One of the key pieces of evidence used to support the identification of Ireland as Ogygia is a passage written by Plutarch, a historian of the first century CE. He wrote about Homer’s account of Ogygia in conjunction to other additional information he provided. According to Plutarch, Ogygia was situated to the west of Britain, which is where Ireland is in fact located.

Additionally, Plutarch tells us that Ogygia was five thousand stadia away from the ‘great continent’ which surrounded the ‘great sea.’ Several scholars have suggested that this ‘great continent’ actually refers to America. Examples include Wilhelm von Christ, an eighteenth-century German scholar, and Johannes Kepler, a sixteenth-century German scholar.

If the ‘great continent’ mentioned by Plutarch really was America, then that would mean that Ogygia was actually an island somewhere between Britain and America. Since Plutarch says that Ogygia was five thousand stadia from the great continent but only several days distant from Britain, this indicates that it was much closer to Britain than to America. Therefore, Ireland would seem to be a good match.

Problems with identifying Ogygia as Ireland

While Ireland does match Plutarch’s basic description, there are certain issues with this identification. For one thing, Ireland is not five thousand stadia from America. This distance would be the equivalent of a little over nine hundred kilometers. Nevertheless, the distance between Ireland and America is about three thousand kilometers.

Hence, the distance specified by Plutarch means that Ireland is in fact not Ogygia, if America was indeed the ‘great continent’ to which he referred. Clearly, however, there is no other option for the great continent that would fit the passage.

Another problem is that Plutarch states that it takes five days of sailing to travel between Britain and Ogygia. This would indicate an island much further west than Ireland because it would barely take two days of sailing to reach Ireland from the furthest part of the western side of Britain.

In reality, there is no island which is exactly five days’ sailing away from Britain and also five thousand stadia away from America. The measurements simply do not correspond to any real location.

Perhaps, then, some researchers could use this as evidence that the measurements must be incorrect, meaning that Ireland could still be the intended location. Alternatively, it could of course also mean that Plutarch was not really describing an actual location at all.

Top Mythological Sites in Greece

There is something about Greece that sets it apart from many other holiday destinations across the globe; its mythological sites.

Many ancient societies had different beliefs and myths, but none are more prominent in modern-day life than that of the Greeks. Their creatures have become legends, their tales inspiration for great fiction and their gods immortalized through the continued retelling of their conquests and trials.

Delos: an ancient mythological site in Greece

Matched only by the Acropolis of Athens, Greek mythological site the ruins on the island of Delos are an unmissable location for anybody interested in ancient Greek culture. One of the best-preserved examples of an ancient Greek civilization, the island is completely unblemished by modern architecture and as such, allows its visitors to delve deep into history.

However, it is not just a site of great historical importance, but a mythological one too. It was on this island that both gods Artemis and Apollo are said to have been born. As a result, the island became a sacred place. Sanctuaries and temples sprung up across its hillsides as people from across Greece came to the island’s shores to worship the deities.

The Labyrinth, a famous site in Greek mythology

One of the most famous and exciting stories of Greek mythology is the tale of Minos, Theseus and the Minotaur. Minos was a powerful king, ruler of Crete and the son of Zeus, but after he betrayed Poseidon, he was cursed to raise a son with the body of a man and the head of a bull. Using this curse to his advantage, however, Minos built the fabled Labyrinth and trapped the Minotaur within it. He would then send victims to their deaths until Theseus, prince of Athens, ventured into the Labyrinth and slayed the beast.

While there are no Minotaur bones for you to see, there are two possible Labyrinths to explore. First is the likely home of King Minos, and therefore the most plausible home for the labyrinth, Kommos. Located along the southern coast of the island, Kommos is a great place to visit, with spectacular ancient ruins and beautiful ocean views.

However, if you venture deep enough into the ruins of this ancient city, you will find many maze-like corridors and walkways that may have been the Minotaur’s home; or at least the inspiration for its tale. However, just down the road you will also find Gortyn, a site of great archaeological importance to Crete and another suspected home of the Labyrinth. Further away from Minos’ home, these ruins bear a much similar resemblance to the maze of mythology. Perhaps then, it is best to visit both Greek mythological sites and decide for yourself.

The Island of Ithaca: an ancient Greek site and holiday destination

Ithaca, a well-known Greek mythological site for a holiday destination, is a place with a very interesting mythological past. Most notably, it was home to the legendary trickster Odysseus, the island’s greatest king and the brains behind the trojan horse.

Odysseus was also the protagonist of Homer’s “Odyssey.” His decade-long struggle to return home after the war is the source of many of the most enduring Greek myths.

The famous Cave of Zeus on the Greek island of Crete

Hidden away on the island of Crete is an extraordinary piece of Greek mythological history. Within a cave beneath Mount Ida, it is said that the King of Gods, Zeus, was born and raised.

The Cave of Zeus is a beautiful location, with one entrance leading into a network of caves filled with stunning rock formations and underground pools. It does indeed seem a fitting place for the beginnings of the greatest god Greek mythology has ever known. However, it was not by choice he was raised here but by necessity.

His father, the titan Cronus, was set on devouring all of his progeny to ensure that they could never contest his power. However, unbeknownst to Cronus, Zeus’ mother, Rhea, hid him within the cave so one day he could return to overthrow his tyrannical father; which, according to legend, he did.

Mount Olympus: Home of the Greek gods

Along the eastern coast of the Greek mainland, you will find one of the most well-known natural landmarks in the world; Mount Olympus. This legendary and iconic Greek mythological site is an awe-inspiring sight, however, there is more to it than meets the eye.

In Greek mythology, Olympus was created after the gods defeated the titans in the battle of Titanomachy; otherwise known as the War of the Titans. Atop its peak they then built the Pantheon, where Zeus sat upon his throne as King of Gods and the rest of the deities would convene to discuss matters of the world below and survey the world of men.

Seeing all these incredible mythological sites can be tricky, unless you charter a course aboard Deep Blue Yachting’s luxury sailing boat, the Glaros. It is a private vessel, you can set your own course and visit every site on this list, all in one trip.

Alexander the Great’s Encounters With Sea Monsters

As one of the most famous figures in human history, it comes as little surprise that the life of Alexander the Great is tied to several legends of mythic proportions, of which several concern the conqueror’s encounters with sea monsters.

Alexander’s armies traversed much of the known ancient world, leaving their native Macedon far behind them. Over the course of their long campaigns, they encountered many strange sights, some of which may have inspired later myths and legends.

At least two historians, from the ancient and medieval periods, described Alexander the Great and his encounters with sea monsters. The first was Diodorus Sciulus, a Greek historian of the 1st century BC and the Arab scholar Ibn Khaldun of the 14th century AD.

The sea creature at the siege of Tyre, 332 BC

In 323 BC, the intrepid Macedonian king laid siege to Tyre, a well-fortified Phoenician city-state on the coast of the Mediterranean. The city was extremely difficult to penetrate because it was located on an island and was defended by high walls that came right up to the sea.

Nevertheless, it was necessary to capture Tyre to deny the Persians access to a strategically important naval base. Thus, Alexander ordered his engineers to prepare artillery pieces and siege works for an assault on the city.

However, whilst this effort was underway, a strange event in which the army of Alexander the Great encountered a sea monster in the waters around Tyre occurred, according to the writings of Diodorus Siculus.

“As the Macedonian construction came within range of their missiles, portents were sent by the gods to them in their danger,” wrote Diodorus Siculus.  “Out of the sea, a tidal wave tossed a sea monster of incredible size into the midst of the Macedonian operations.”

“It crashed into the mole but did it no harm, remained resting a portion of its body against it for a long time and then swam off into the sea again,” continued the Greek historian. “This strange event threw both sides into superstition, each imagining that the portent signified that Poseidon would come to their aid, for they were swayed by their own interest in the matter.”

A less fantastical explanation for this incident is possible than a mythical sea monster sent by Poseidon. The creature in question may have been a shark, dolphin, whale, or other entirely normal aquatic inhabitant.

Alexander the Great and the sea monsters of Alexandria

The siege of Tyre was not the only time Alexander is said to have encountered a sea monster. According to the Arab scholar Ibn Khaldun, he saw several mythical aquatic beasts in Egypt.

In fact, Ibn Khaldun claimed that sea monsters initially halted the construction of Alexandria until Alexander devised a way to scare them away from the area.

“Sea monsters prevented Alexander from building Alexandria,” wrote the scholar. “He took a wooden container in which a glass box was inserted, and dived in it to the bottom of the sea. There he drew pictures of the devilish monsters he saw.”

According to Ibn Khaldun, “He then had metal effigies of these animals made and set them up opposite the place where building was going on. When the monsters came out and saw the effigies, they fled. Alexander was thus able to complete the building of Alexandria.”

Greek Mythology’s Mysterious Eridanos River May Point to a Real Place in Europe

The Eridanos River of Greek mythology is a mysterious river whose location has long been debated. Numerous real-world rivers around Europe have been suggested, but some scholars believe it is completely mythical and corresponds to no real-world location. Nevertheless, some may wonder where this river might actually be situated.

The Eridanos River of Greek mythology

To try to understand which real-world river it might correspond to, we first need to look at what ancient sources say about it. The Eridanos River is most famous for its connection with Phaethon and amber. In the relevant legend, it’s the river into which Phaethon crashes after he steals the chariot of the sun god.

Phaethon’s sisters, the Heliades, grieved the loss of their brother, and the gods transformed them into poplar trees. These trees, in turn, supposedly produced amber for which the river was well known. Numerous scholars have attempted to use this information to identify this body of water.

Furthermore, we know that the Eridanos River cannot have been an obscure, minor river. Hesiod mentions it in his list of the offspring of Oceanus. Eridanos appears first in the list, and Hesiod even calls it “deep-swirling,” which is an expression normally reserved for the great Oceanus itself.

Where was the Eridanos River?

With these facts in mind, what have scholars argued about the location of this river? Well, one popular candidate is the Vistula River, since this flows through Poland and leads to the Baltic Sea. This was a major source of amber in the ancient world, and this fits the criterion of the Eridanos River being a source of amber.

Furthermore, Herodotus associates the Eridanos River with a certain “northern sea.” Since the Baltic Sea is to the north of Greece, it could fit Herodotus’ description. However, another popular candidate is the Po River, which flows through northern Italy and enters the Adriatic Sea. In fact, several ancient sources explicitly identify the Eridanos with this real river. At first, that might seem to settle the matter. However, it’s more complicated than that.

A closer look at Herodotus’ description

Herodotus, in the fifth century BC, was not the first person to mention the Eridanos River. As we saw earlier, that was Hesiod. However, he does seem to provide the earliest useful description of it. His description reads:

“As to the extremities of Europe towards the West, I am not able to speak with certainty: for neither do I accept the tale that there is a river called in Barbarian tongue Eridanos, flowing into the sea which lies towards the North Wind, whence it is said that amber comes; nor do I know of the real existence of the Cassiterides from which tin comes to us… However that may be, tin and amber certainly come to us from the extremity of Europe.”

As we can see from this description, the Eridanos River was explicitly said to flow into the sea which lies towards the North Wind, and Herodotus refers to this region as the “extremity of Europe”. This definitively rules out the Po River, which flows into the Adriatic Sea near Greece itself.

Does this mean that the Vistula River is the most likely candidate? At first, that might seem to match Herodotus’ reference to the “extremity of Europe” and the fact that the river flowed into the sea towards the North Wind. However, that does not work either. Herodotus prefaces this passage by referring to the “extremities of Europe towards the West”.

Since the Vistula and the Baltic Sea are essentially directly north of Greece, this does not match this aspect of Herodotus’ description.

Jason and the Argonauts

The Argonautica, by Apollonius Rhodius of the third century BC, reveals the answer to this conundrum. Although it contains some fictional geography, it is clear about where the Eridanos River was supposedly situated, and this aligns perfectly with Herodotus’ description.

According to Apollonius, Jason and the Argonauts sail from the Black Sea through the Danube and then reached the Adriatic Sea via a fictional channel between the two. They then sail up into the Eridanos River, actually signifying the Po River in this context. Eventually, they make it to the Rhodanus River, or the Rhone as it is known today, a body of water which flows through France relatively close to the Po River source and then spills into the the Mediterranean Sea on the country’s southern coast.

This is significant because it demonstrates that the Greeks believed the Po and the Rhone were connected. In fact, other ancient texts attest to this same belief. Consequently, this means Apollonius is presenting the Rhone as part of the Eridanus River.

How the Argonautica reveals the true location of the Eridanos River

At this point in the Argonautica, the true nature of the Eridanos River is made clear. Apollonius writes:

“Thence they entered the deep stream of Rhodanus which flows into Eridanus; and where they meet there is a roar of mingling waters. Now that river, rising from the ends of the earth, where are the portals and mansions of Night, on one side bursts forth upon the beach of Ocean, at another pours into the Ionian Sea, and on the third through seven mouths sends its stream to the Sardinian sea and its limitless bay.”

Apollonius refers to the Eridanos River as having three mouths. One arm of the river flows into the Ionian Sea, which is an ancient reference to the Adriatic Sea. That is the arm of the river that Jason and the Argonauts have just been described as sailing up. Another one of the arms of the river is said to flow into the Sardinian Sea. That would be the Rhone, in accordance with Apollonius who explicitly presents the Rhodanus (the Rhone) as part of the Eridanos.

The third arm is the final piece of the puzzle. According to Apollonius, it flows into the “beach of Ocean.” Incidentally, this matches Herodotus’s description of the Eridanos flowing into the sea on the other side of Europe, which doesn’t match the Rhone nor the Po. The notable point is that this shows that the Ancient Greeks believed the Po, the Rhone, and a third river were all part of one enormous waterway in Europe, which they referred to as the Eridanos.

What was the third arm of the Eridanos River?

A few lines later, Apollonius refers to the mouth of the river in the southern part of France as the middle of the three mouths of the Eridanos. With the Po River having the mouth closest to Greece, and the Rhone having the intermediate one, the third mouth must have been even further west. This, again, is in harmony with Herodotus’ description, which associated the Eridanos with the western extremity of Europe.

Based on this, the only plausible candidate for the third arm of the Eridanos River is the Loire. This is a river whose mouth is further west than the mouth of the Rhone. It flows out into the Atlantic Ocean on the western side of France and is located towards the north—another detail of Herodotus to keep in mind. Furthermore, it flows quite close to the Rhone near its source, making sense of the belief that they were connected.

In summary, it appears that the Greeks imagined the Loire, the Rhone, and the Po Rivers to all be connected. The Greeks received their amber via the Po River, since it was the final part of the Amber Road which originated in the Baltic Sea. However, they believed that the Po was connected to the Loire.

This perfectly matches up with Herodotus’ description of the Eridanos River in its entirety. As we saw, he claimed it flowed into the sea on the other side of Europe and associated it particularly with the north and the west, which points to the Loire.
