ENThe main attention in the article is paid to the documents from Lithuanian Metrica concerning the functioning of the institute of “staryna” [old times] in the Grand Duchy of Lithuania. A short historiographical review and analysis of the group of public nature sources were made in particular. The following documents belong to the group of the public nature sources: lists/charters [lyst/ hramota], privileges, confirmations, liberties documents [vol’nost’], lease agreements and diplomatic acts. The judicial documents represented by cases [sprava], adjournment of cases, sentences [vyrok/dekret/ukhvala] were studied too. The source study analysis shows that the examined groups of public and judicial documents contain direct or indirect appeals to the institute of “staryna”.
