Niniejszy tekst przedstawia historię komety, która pojawiła się na niebie po śmierci JuliuszaCezara w lipcu 44 roku p.n.e. Komety uważano najczęściej za złe znaki, przynoszącewojny i klęski, dlatego też przed młodym Oktawianem stanęło szczególnie trudne zadanieprzekształcenia złowróżbnego omenu w symbol własnego panowania. Z początku ukrywałon prawdziwą naturę zjawiska, w swojej propagandzie wizualnej nadając mu postaćgwiazdy. Dopiero po dwóch dekadach, kiedy jego władza okrzepła, przyjmując formę PaxAugusta i aurea aetas, Oktawian mógł otwarcie przyznać, że była to kometa. Ta luka źródłowasprawiła, że niektórzy uczeni zaczęli powątpiewać w realne istnienie tego zjawiskaastronomicznego. W tekście tym przytaczam argumenty przemawiające za historycznościąkomety Cezara oraz pokazuję, dlaczego Rzymianie skłonni byli uznać ją za znak apoteozyboskiego Juliusza.

The text presents the story of a comet which appeared after the death of Julius Caesar inJuly 44 BC. Comets were usually considered as bad omens bringing wars and disasters.Therefore, young Octavian had a very difficult task to change this sinister sign into a symbolof his rulership. At the beginning, he disguised the real nature of this phenomenon,presenting it as a star in his visual propaganda. Only after two decades, when his powerwas established in the form of Pax Augusta and aurea aetas, Octavian could openly admitthat it was a comet. This gap in the sources made some scholars doubt the real existence ofthe astronomical phenomenon. My text delivers arguments for historicity of the Caesar’scomet and shows why Roman people were inclined to consider it a sign of apotheosis ofdivus Julius.

Stanisław Lubieniecki (1623-1675), best known for his work as a historian and theologian of the Polish Brethren, published also the Theatrum cometicum (Amstelodami 1666-1668) devoted to cometary studies. The first volume of that book contains the author’s astronomical correspondence with dozens of more or less renowned scholars of various fields of knowledge. By initiating scientific correspondence, Lubieniecki attempted to act as an intermediary in conveying information in 17th century Res Publica Litteraria. The article explains this activity on the basis of several examples: the issue behind the total number of comets in 1664 and 1665, the phenomenon in the Andromeda Galaxy and Lubieniecki’s correspondence with Henry Oldenburg. It shows how a layman in the world of science seeks to find a place for himself in the republic of scholars.

The correspondence with Stanisław Lubieniecki (1623–1675) is the fourth most voluminous in the corpus of letters of Johannes Hevelius (1611–1687) – there are over ninety letters they wrote to each other between 1664 and 1673. Their positions in the learned world, however, were very unequal. Hevelius was a reputed astronomer and a fellow of the Royal Society, while Lubieniecki was an amateur interested in comets and astronomy. In this paper, I present the goals they have in this correspondence and the ways in which they tried to achieve them, and I try to explain why their correspondence was so numerous and long-lasting.
