The Museum in Kwidzyn has in its keeping material from two Lusatian culture cemeteries studied by Waldemar Heym – for many years head of the Heimatmuseum Marienwerder: Rybitwy, comm. Bobrowniki, distr. Lipno and Sitno, comm. Zbójno, distr. Golub-Dobrzyń (former Sittenfeld, Kr. Leipe), both in woj. kujawsko-pomorskie (Fig. 1). Neither of these sites was ever published. The cemetery at Rybitwy, investigated in 1940, figures in the inventory book of the Heimatmuseum Marienwerder under no. 3260 as Rybitwy, Kr. Lipno, Gräberfeld d. Lausitzer. The study of evidence from Rybitwy prepared by W. Heym pending publication in the successive annual issue of Gothiskandza was lost during the war. All that remains from pre-war research are nine vessels labelled “Rybitwy”, now in the collection of the Kwidzyn Museum. As for the cemetery at Sitno, apart from five vessels from that site no information about the cemetery is found in archival records of W. Heym surviving in the Museum. Pottery from Rybitwy and Sitno represents forms typical for Bronze Age period IV and V. Of special interest are two vase-shaped vessels with a broad rim from Rybitwy (Fig. 2:2.3). The only questionable piece is a miniature vessel from the same site showing traces of burning (Fig. 3:2) – a form wholly foreign in Lusatian Culture, but a distinctive form in Wielbark culture of the Late Roman period. Apparently, the piece in question was assigned to material from Rybitwy by accident. Both sites are situated in the Lipno region of Lusatian Culture distinguished by J. Dąbrowski (1997, p. 93, 97, map 3), as yet poorly understood. Settlement in this area evades classification to any of the neighbouring groups of Lusatian culture (ie Kulmerland, Northern Masovia, Eastern Great Poland). Postulated strong links with the latter group are not substantiated by material presented in the present article; rather, they suggest convergence with the Northern Mazovian and possibly, the Kulmerland group; nevertheless, it should be remembered that the surviving artefacts form a mere fraction of evidence recovered at the two burial grounds.
