INTRODUCTION At the western border of the ancient world, there was a country where the Mediterranean opened to the Atlantic Ocean. Greek sailors returned from here with extraordinary wealth, Phoenician traders reached the region's mines and ports, and ancient writers described a country that was almost legendary with its silver, rulers, and remoteness. Its name was Tartessos . However, what makes the story of Tartessos extraordinary is not just its wealth. The exact location of the capital of Tartessos, which emerged as an important kingdom and trade center in ancient sources, is still not definitively known today. Only a few names of the kings who ruled it have survived, its language has not been fully deciphered, the boundaries of its political structure cannot be determined, and visibility in classical sources largely ended just a few generations after its brightest period. Archaeology has made the story even more complex. Because today, when we talk about Tartessos, we are faced not only with a lost city but also with a vast and extremely complex cultural area formed as a result of the interaction between indigenous communities and the Phoenicians in southwestern Iberia for centuries, connecting the Mediterranean and Atlantic worlds. Modern research is increasingly emphasizing the evaluation of Tartessos not as a single "lost kingdom" but as a political, economic, and cultural world that developed around the Lower Guadalquivir . The Country at the End of the World Some of the most impressive information about Tartessos is conveyed by the historian Herodotus , who lived in the 5th century BC. In his narrative, Tartessos is not an ordinary neighbor of the Greek world. It is a very distant yet wealthy country located beyond the Strait of Gibraltar, the "Pillars of Heracles" of the ancient world. At the center of the first story recounted by Herodotus are the sailors from Phocaea. The Phocaeans are considered among the first Greek communities to embark on long sea voyages, and it is said that they reached as far as the Adriatic, Etruria, Iberia, and Tartessos. When they arrived in Tartessos, they established friendship with a ruler named Arganthonios . Herodotus recounts that he ruled Tartessos for eighty years and lived for 120 years. It is impossible to verify the historical accuracy of these figures; the motif of longevity suggests that the ruler may have transformed into a legendary figure in ancient times. However, the political content of the narrative is striking. It is said that Arganthonios offered the Phocaeans to settle in his country, and when they refused, he gave them a large amount of money so they could fortify their own cities against the rising Persian threat. In other words, in Herodotus's world, Tartessos is not just a distant region from which minerals are extracted; it is an organized political power that can establish diplomatic relations with foreign states, rich and ruled by a king. Herodotus's other narrative is even more striking. The ship of the Samian merchant Kolaios is blown off course by the wind while heading to Egypt and is swept to Tartessos after passing the Pillars of Heracles. Herodotus describes this place as a market that had not yet been heavily used by Greek merchants at that time. Kolaios and his men return with such a great profit that they set aside six talents from one-tenth of their earnings to make a large bronze offering at the Hera Temple in Samos. It is impossible to know how much of these stories contain literary embellishment. However, archaeology confirms the fundamental truth behind the tales: Southwest Iberia was indeed an extremely important trade region that attracted the Mediterranean world of the time. Where Exactly Was Tartessos? Here begins one of the greatest mysteries of Tartessos. In ancient texts, Tartessos sometimes appears as a city, sometimes as a region, sometimes as a river, and sometimes as a political entity. In modern archaeology, however, the core region of Tartessos is generally placed in today's Huelva, Sevilla, and Cádiz area and the Lower Guadalquivir basin . The issue is that the coastline in ancient times was quite different from today. In the area where the Guadalquivir reaches the sea, there were wide estuaries, islands, lagoons, and swamps. Thousands of years of sedimentation, river movements, and coastal changes transformed a significant part of ancient geography. Therefore, places described by ancient writers as "island," "lake," "river mouth," or "port" can now be located kilometers inland. This topic is particularly important due to Avienus's work titled Ora Maritima . Although Avienus lived in the 4th century AD, it is believed that some of the geographical information he used in his poem may be based on much older maritime sources, possibly traditions dating back to the 6th century BC. In 2024, a study published by Juan J. R. Villarías-Robles, Antonio Rodríguez-Ramírez, José Antonio López-Sáez, Sebastián Celestino-Pérez, and Ángel León re-examined the descriptions in Ora Maritima with modern geomorphology and paleoenvironmental research. The researchers suggested that the city of Tartessos might have been located in the area known today as La Algaida ; they argued that this place was an island in the 1st millennium BC. However, a critical distinction must be made: The city of Tartessos has not been found. The La Algaida model is currently a scientifically debatable hypothesis, but the article itself acknowledges that the hypothesis needs to be tested with archaeological and geophysical studies. Therefore, popular statements such as "the lost capital of Tartessos has been found" overshadow the scientific situation. The mystery of Tartessos continues to live on right here: Ancient writers may have mentioned a center, but the remains of this center have not been definitively identified today. Modern researchers are therefore directing their energies not only towards finding the lost capital but also towards understanding how the entire world of Tartessos operated. Silver, Minerals, and a Trade Empire One of the fundamental elements behind the wealth of Tartessos was the extraordinary mineral resources of Iberia. Southwestern Spain was one of the most remarkable regions of the Mediterranean world in terms of silver, copper, lead, and other minerals. However, viewing Tartessos merely as a "mining kingdom" is incomplete. The location of Huelva on the estuary formed by two accessible rivers, its access to nearby mining regions, and its connection to routes extending to the Atlantic coasts of Portugal made it a natural trade center. Finds in Huelva indicate that Phoenician trade may have extended to the first half of the 9th century BC. The presence of materials in the same archaeological layers that show connections to the Phoenician world, as well as Cyprus, Greece, Etruria, and Sardinia, reveals that the region was not a one-way trade colony. Remnants of metallurgy, slags, tools, ivory, and traces of various craft productions also suggest that there were not only temporarily visiting sailors at trade centers but also communities of artisans and merchants living there permanently. Moreover, the idea that the Phoenicians were only interested in metals is being abandoned today. Agricultural products, livestock, timber, and other resources were important parts of Western Mediterranean trade. Therefore, the wealth of Tartessos seems to have originated not from a single silver mine but from a vast economic network formed between the Atlantic and the Mediterranean . Did the Phoenicians Create Tartessos? This is one of the biggest debates in Tartessos research. In ancient models, the story was told quite simply: the advanced Phoenicians came from the East, traded with the local people, and "civilized" their culture. Modern archaeology finds this schema largely inadequate. The Phoenician influence is undeniably significant. From the 8th century BC onwards, elements of Eastern Mediterranean origin become prominent in religious symbols, architecture, metalworking, burial practices, and trade systems. However, it is not possible to explain all of these as mere cultural imitation. The archaeological data evaluated by María Belén Deamos suggest that Phoenicians and local communities may have lived side by side for a long time in certain centers; in addition to traders, artisans, farmers, and other groups may have settled in the region. The resulting culture is neither entirely Phoenician nor a continuation of the ancient local tradition without change. Rather, it is a hybrid social space where two worlds intermingle. Therefore, it is difficult to provide a simple ethnic answer to the question "Who was Tartessos?" today. Tartessos was likely a geography where different local communities, Phoenician immigrants, and people from other regions of the Mediterranean blended through trade, marriage, religion, politics, and daily life. Colonial Encounters in Ancient Iberia thus considers Tartessos not as a uniform culture, but as a complex region extending from Cádiz to the inland areas of the Guadalquivir, where local and Phoenician elements merged in different proportions. The Same Routes of Gods and Traders In the world of Tartessos, trade and religion were not completely separate from each other. The sacred sites uncovered along the trade routes at the mouth of the Guadalquivir indicate that there were strong relationships between the safety of sailors' journeys, commercial agreements, and the circulation of goods with religious institutions. In the structures excavated in Coria del Río, sacred areas built on top of each other have been identified between the 8th and 6th centuries BC. In one of them, an altar made in the shape of a bull's hide, Egyptian-origin scarabs, painted ostrich egg fragments, and cattle horns were found. Researchers associate the altar with the Baal cult. The location of the structure is also noteworthy: it served as a landmark for both sea and river transportation and allowed for the control of trade routes leading to the interior regions. The nearby El Carambolo is one of the most famous centers of Tartessos research. In 1958, a treasure consisting of extraordinary gold artifacts was discovered here. Subsequent excavations showed that the area could not be interpreted as a simple native settlement; the possibility of a sacred area and Phoenician connections gained increasing importance. The seated Astarte figurine found in the region also strengthened the debate. All of this shows that Tartessos was not merely a wealthy society engaged in mining; it created a complex system that linked trade routes, sacred areas, and political power. The Forgotten Language of Tartessos One of the strongest ways to recognize a civilization is to hear its own voice. What we lack regarding Tartessos is precisely this. The system used in Southwestern Iberia, often referred to as Tartessos script or Southwestern script , is one of the oldest indigenous writing traditions of the Iberian Peninsula. It is believed to have developed under the influence of the Phoenician alphabet. Inscriptions have been found over a fairly wide area, from southern Portugal to Extremadura and around the Guadalquivir. Although a significant portion of the basic signs of the script can be read, this does not mean we understand the language. Being able to approximately read the sounds of a text is not the same as knowing what the words mean. As noted by Erkan Yurtaydın in the Turkish literature, a significant portion of the available examples dates back to the 7th to 5th centuries BC, and the system used combines alphabetical signs with syllabic signs. There are still serious uncertainties regarding the meaning of the texts and the classification of the language. Therefore, there are writings from the people of Tartessos that have reached us from hundreds of years ago, but we cannot yet fully read the story they tell. This sit
