The article focuses on the author’s comments (remarques) found in the Old German classic works like Hildebrandlied, Georgslied, Otfrids Evangelienbuch, Muspilli and others. Writers are considered to be metasubjects. Being a metanarrative element, an author’s comment can serve as a means of the teller’s self-presentation, expression of his views on the form and content of the statements and so forth. In doing so, the key functions are organizing the text space and optimizing the process of the text reception. The role of the author's comment and the set of its functions is conditioned by specific genre and style. Special significance author’s comments gain in the literary works created centuries ago. An author can express him- or herself using “narrative techniques” and “meaningful assessments” (K. Felkel). According to another classification, phatic, emotional and interpreting functions of the author's presence are defined. Of particular interest in the works of Old German culture are evidential comments, as well as those foreseeing and initiating the soonest activities of a recipient. On the material of the aforementioned works we analyze a complex of lexical and grammatical means of the author’s “invasion”, namely self-nomination, introductory patterns, verb forms, modal items expressing cognitive position of the author, rhetorical devices, evidential-epistemic constructions and so on. The most popular constructions in Old German works are I-constructions testifying to possession of some knowledge. Evidentiality of the knowledge is emphasized by references to oral and written sources, the Gospels being the most influential among them.
