By the 3rd century BCE Celtic art began to penetrate into southern regions of Ukrainian territory. In Roman provinces a renaissance of Celtic handicrafts took place, in particularly in the form of jewellery. These ornaments were introduced near the Black Sea and points further north. Another entry point for Celtic jewellery into the present day territory of Ukraine was trade and cultural contacts with northern tribes. Celtic art and culture spread into the British Isles, Germany and the Baltic Sea coast and from there into Ukraine. Every region in Ukraine shows some Celtic influence in the styles of arms and jewellery production. Jewellery making traditions of Ukraine also influenced other cultures. For example, the Goths came to the area sometime before 400 CE and adopted some of the techniques prevalent in Ukraine, including polychrome and animal styles later reflected in the Merovingian style of jewellery.
