LTStraipsnyje analizuojamas, pirmą kartą publikuojamas ir į lietuvių kalbą išverčiamas 1529 m. sausio 12 d. Lietuvos Didžiosios Kunigaikštystės ir Livonijos konfederacijos sienos aprašymas. Nustatyta dalies toponimų lokacijos, kurios iki šiol nebuvo žinomos. Aiškinamasi dokumento sudarymo ir archyvavimo aplinkybės. Keliama hipotezė, kad dokumento juodraštį sudarė Aleksandras (Alekna) Krivecas, vėliau jį perdavė saugoti kancleriui Albertui Goštautui. Esminiai žodžiai: Lietuvos Didžioji Kunigaikštystė, Lietuvos Metrika, Livonija, siena. [Iš leidinio]
ENThis article is aimed at providing the first publication, analysis and Lithuanian translation of the description of the border between the Grand Duchy of Lithuania and the Confederation of Livonia, as dated on 12 January 1529. The comparison of the 1529 description with the previous treaties (1367, 1426, 1473) shows that the border largely coincided in several sections, namely, between the Daugava River and Kurcumas/Kurcums Lake in 1473, along the Dienvidsusēja River in 1367, and between the Nemunėlis/Mēmele River and the Mūša/Mūsa River in 1426. On the other hand, the border between the Mūša River and Buknaičiai Village (Mažeikiai District) and further westward along the Šventoji/Sventāja River was substantially moved northward for the advantage of Lithuania. Covering the 590 kilometre frontline (approximately 270 kilometres out of them along rivers excluding their curves), the 1529 border description lists 19 parishes, 30 rivers and streams, 17 lakes and 1 island, 2 marshes, 4 hills and 2 mounds, 2 settlements (Žagarė and Bauska), 1 stackyard (near Bauska), 1 estate (near the Viršytis/Virsīte River), and 1 village (in the confluence of the Švitinys/Svitene River and the Viršytis River). In total, the description contains 79 toponyms. The part of the border described in 1529 coincides with the current state border between Lithuania and Latvia (from the Skirna River to Samanka Lake, from Kastantinava Village to Subatas Lake (Latvian: Mazais Subates ezers), from the Virčiuvė/Vircava River to Žagarė, from Buknaičiai Village to the Šventoji River) (see Annex No 3). This section underwent slight changes as far back as on 30 March 1921. No other objects are mentioned in the description of the border between Kurcumas/Kurcums Lake and Subatas Lake.The article also investigates the circumstances of creating and archiving the border description. A hypothesis is suggested that the document had been drafted by Alexander (Olechno) Krivec and was later transferred to chancellor Albertas Goštautas (Polish: Olbracht Gasztołd; Belarusian: Альбрэхт Гаштольд; Russian: Ольбрахт (Альберт) Гаштольд)) for storage. Keywords: Grand Duchy of Lithuania, Lithuanian Metrica, Livonia, border. [From the publication]
