ENThe conducted study confirmed and extended the hypothesis developed by Konstantinas Jablonskis 60 years ago that the lists of books contained in Book No. 223 of the Lithuanian Metrica may be attributed to Albertas Goštautas (rus. Ольбрахт (Альберт) Гаштольд; bel. Альбрэхт Гаштольд; pol. Olbracht Gasztołd). A codicological and paleographical analysis of Lithuanian Metrica Book No. 223 revealed that A. Goštautas did own not only the books but the rest of the listed property (weapons (cannons), armor, clothes, harnesses, tableware, tapestries, paintings of saints, etc.). The time when the lists were compiled and the arsenal described suggests that some part of the property must have been kept in the Goštautas family‘s homeland and principal residence of A. Goštautas himself – Geranainiai (now Geranainiai, Iwye District, Belarus). Keywords: Grand Duchy of Lithuania, Lithuanian Metrica, Albertas Goštautas, Geranainiai, movables, cannons, luxury.
