Belorussian-Lithuanian chronicles are very important in the literature of the Grand Duchy of Lithuania. They were gradually modified from annual records to narrative forms, which made them similar to West-European chronicles. The analysis of the praesens historicum forms in two 16th-century chronicles: the Suprasl chronicle and Raczynski`s chronicle was made in the article. Both texts contain examples of the praesens historicum forms which very often appear in abundant forms of the past tense. The examples of the praesens historicum forms in plural shown in both chronicles deny one of the theories of the praesens historicum originating from the aorist. There are also other theories explaining the origin of the praesens historicum but they do not fully clarify this issue.
