This paper considers brooches of the 5th–6th century AD distributed throughout the basins of the North and connected with the maritime Aestii in the territory of what is now Kaliningrad Oblast in Russia. These artefacts are important for studies of ancient interregional and intercultural contacts since, in the traditional communities, elements of women’s attire, including ibulae, are among the most conservative features of material culture. Here some arbalest-shaped brooches (types of Schönwarling, Duráton, Estagel, Rouillé), as well as ibulae with a rhomboid foot-plate and rectangular or semispheric head (types of Monsheim– Liebenau–West Stow and Breitenfurt), fingered brooches (types of Koch III.5.5 and Domburg – Koch IX) are considered. The spread of these ibulae was taking place in connection with establishing the trans-European oceanic route along the southern coast of the North Sea and Baltic Sea region. This route passed through Danish straits and via Jutland with the inal transhipping point at the base of the Jutland Baltic seas and found at sites of the Sambian–Natangian (Dollkeim–Kovrovo) culture believed to have been isthmus. The role of trade in these contacts is undoubted, however political alliances between different tribes, as well as merely war events (plundering raids) were of no less importance. The spread of elements of women’s attire in traditional societies, except for certain articles (e.g. beads) cannot indicate the existence of trade connections since the female costume had a special sacral status and was transferred only with its bearers. Therefore the appearance of ‘female’ articles of the Sambian-Natangian culture outside the limits of their main area relects primarily marriage links. These, as a rule, ixed the military and political ties between different barbarian peoples. The materials here published pertain to no prestigious ‘princely’ civilisation but relect the material culture of the ‘middle class’ which, as it seems, also participated in the ixation of the interregional and intercultural contacts through ‘mixed marriages’.
