Zabytki z wczesnośredniowiecznych cmentarzysk z grobami w obudowach kamiennych pochodzące z badań Nikolaja P. Awenariusa

The aim of this paper is putting into scientific circulation archaeological finds from eight early medieval burial grounds with graves in stone-settings, from the area of Podlaskie Voivodeship (norh-eastern Poland). The finds come from excavations conducted by Russian researcher Nikolai Avenarius in 1887 and 1888. For a long time his collection, which is kept in the State Historical Museum in Moscow, has been considered to be lost. This is the reason why despite of that 130 years had passed since N. Avenarius’ excavations, hardly any information about his collection can be found in archaeological literature.
