The article delivers an analysis of German text by the Russian philosopher and classical philologist A.F.Losev (1893–1988) published below which contains four annotations of his earlier works. The author discusses the question of it's dating and shows that the annotations present brief summaries of Losev's treatises which have been later partially used as material for his published books. The treatise “General aesthetics from the dialectical viewpoint” has given materials for two books “The dialectics of the artistic form” (1927) and “Music as an object of logic” (1927), the study “The theory of number in the ancient Greek philosophy” has been published in parts as two studies “Dialectics of number in Plotinus” (1928) and “Aristotle's critique of Platonism (1928), the three-volume “Philosophy of name' has been shortened up to the published version оf “The philosophy of name” (1927), finally the monography “The philosophy of Plotinus” has become one of the sources for the book “The ancient cosmos and the modern science” (1927). Through the textological comparison of German annotations with the published works by Losev the author comes to the conclusion they could be dated on the beginning of the 1920s, not later but the summer of 1923. According to the author's hypothesis these annotations togetherb with the other German texts by Losev cold be an evidence for his contacts with german academic scholars at the beginning of the 1920s.
