Polish Archaeological Mission „Tyritake” National Museum in Warsaw Dr. Alla Bujskikh On a typical pottery deposit of the 6th century BC from the Northern Black Sea Region: Olbia Pontica and Tyritake Greek penetration into the Pontic region and following exploration of the northern coast during the last stage of Greek colonization are closely related to the problem of absolute chronology of this process. Written sources concerning the period of colonization are scarce and poor in quality. On the other hand, archaeological sources are numerous already, and their amount can possibly increase with each new campaign. The level of competence of present- day researchers of colonization period, and the organization of the first apoikia in the northwestern and northeastern parts of the Black Sea coast allow comparison of archaeological material from various sites in the region. Moreover, such methods are also used in the process of investigating the foundation of the colonies. Today, the stratigraphy of early archaeological deposits in Olbia is well-known. The category of tableware comprises vessels imported from various centers in the Mediterranean: Southern and Northern Ionia, Chios, Lesbos and mainland Greece – Korinthos, Laconica, and Athens. The island centers and the ones in Ionia are an important source of painted vessels, which are quite similar in Borysthenes and Histria for the end of 7th and the beginning of 6th centuries BC; for Borysthenes, Histria, and Olbia at the turn of the 7th and 6th centuries BC and in the first half of 6th c. BC; for Borysthenes, Histria, Olbia, and Nikonion in the second half and at the end of 6th c. BC. This picture can be applied to some Bosporan sites, like Panticapaion, Panticapaion and Nymphaion, and finally – Panticapaion, Nymphaion, and Tyritake. Each quarter of the 6th c. BC provides very specific amount of painted tableware, which allows distributing them in the whole chronological span. .
