The Penkovka culture (Пеньківська культура Penkivska kultura) is an archaeological culture in Ukraine, Moldova and reaching into Romania. Its western boundary is usually taken to at the middle Prut and Dniester rivers, where contact with the Korchak culture occurs. Its bearers are commonly identified as the Antes people of 6th-century Byzantine historiography. The core of the culture seems to be in Left-bank Ukraine, especially along the Sula, Seim, Psel, Donets and Oril rivers, but its territory extends to Right-bank Ukraine, and Penkovka pottery is also found in eastern and southern Romania, where it co-exists with wheel-made pottery of late Roman derivation; and is referred to as the Ipotesti–Candesti culture by Romanian archaeologists. Penkovka-type pottery has even been found in Byzantine forts in the north-eastern Balkans. "Nomadic" style wheel-made pottery (called Pastyrske or Saltovo ware) also occurs in the Ukrainian Penkovka sites as well as in the lower Danube and Bulgaria, but is most commonly found within the Saltovo-Mayaki culture, associated with Bulgars, Khazars and Alans. One of the ancestors of the bearers of the Penkovka culture were population of Sântana de Mureș—Cherniakhiv culture, which should be described by the culture of the Goths. Since at least the 13th century, the Baltic peoples have called Russians Gudos (Gudos, Gudai), that is, goths. Hand-made Penkovka pottery is distinguished from Prague-Korchak types on the basis of its biconical profile and tendency for out-turned rims. However, Florin Curta has argued that there can be no simple relationship between the type of ceramic vessel and the ethnicity of groups which consumed them. E. Teodor performed a detailed analysis of ceramic vessels in 6th century southeastern Europe, and discovered a complex picture which cannot be reduced to 2 or 3 broad 'archaeological cultures', as each microregion and even individual site shows idiosyncrasies in their ceramic profile and degree of connectivity to other regions of 'Slavic Europe'.
