The existence of foreign produce and materials together with local ones suggests that the old Huelva harbor was a major hub for the reception, manufacturing and shipping of diverse products of different and distant origin. The analysis of written sources and the products exhumed, including inscriptions and thousands of Greek ceramics, some of which are works of excellent quality by known potters and painters, has led some scholars to suggest that this habitat can be identified not only with Tarshish mentioned in the Bible, in the Assyrian stele of Esarhaddon and perhaps in the Phoenician inscription of the Nora Stone, but also with the "Tartessos" of Greek sources –interpreting the Tartessus river as equivalent to the present-day Tinto River and the Ligustine Lake to the joint estuary of the Odiel and Tinto rivers flowing west and east of the Huelva Peninsula. There is very little data, but it is assumed that, like for other Mediterranean peoples, it was a polytheistic religion. It is believed that Tartessians worshiped the goddess Astarte or Potnia and the masculine divinity Baal or Melkart, as a result of the Phoenician acculturation. Sanctuaries inspired by the Phoenician architecture have been found in the deposit of Castulo (Linares, Jaén) and in the vicinity of Carmona. Several images of Phoenician gods have been found in Cádiz, Huelva and Sevilla. The Tartessian language is an extinct pre-Roman language once spoken in southern Iberia. The oldest known indigenous texts of Iberia, dated from the 7th to 6th centuries BC, are written in Tartessian. The inscriptions are written in a semi-syllabic writing system called the Southwest script; they were found in the general area in which Tartessos was located and in surrounding areas of influence. Tartessian language texts were found in Southwestern Spain and Southern Portugal (namely in the Conii, Cempsi, Sefes and Celtici areas of the Algarve and southern Alentejo). Since the classicists of the early 20th century, biblical archaeologists often identify the place-name Tarshish in the Hebrew Bible with Tartessos, though others connect Tarshish to Tarsus in Anatolia or other places as far as India. (See entry for Jonah in the Jewish Encyclopedia.) Tarshish, like Tartessos, is associated with extensive mineral wealth (Iberian Pyrite Belt).
