The eleventh volume in the series presents two articles on the aurora borealis by Friedrich Christoph Mayer (1697–1729), a mathematician at the Imperial Academy of Sciences in Saint Petersburg. The first paper, titled “De Luce Boreali” (On the Northern Light), was presented during a session at the newly founded Academy in October 1726. It was printed two years later (1728) in the very first volume of its official periodical, the Commentarii Academiae Scientiarum Imperialis Petropolitanae. The second paper, also bearing the title “De Luce Boreali”, constitutes the author’s ‘second thoughts’ on the matter. It was presented during a session in October 1728 but was not printed until after Mayer’s death, in the fifth volume of the Commentarii (1735). Both papers are included in facsimile in this issue of Aurorae Borealis Studia Classica. Eric Chassefière, member of the Histoire des sciences astronomiques team of the SYRTE laboratory at the Observatoire de Paris, has written an introduction to Mayer’s life and works with a special emphasis on his theory of the aurora borealis. In his introduction, Chassefière also recounts how Mayer’s theory was received by other eighteenth-century savants.

During the Russo-Turkish War (1768–1774) the expedition organized by the Russian Imperial Academy of Sciences building in Saint Petersburg, in the person of S. Gmelin, for research purposes explored the western shores of the Caspian Sea and the northern regions of Iran. As a result of their research, the ethnography, history and the materials on the customs of the people of these territories are accepted as public value, the spiritual and material values are revealed as well. During the study of the northern provinces of Iran and the Eastern Transcaucasia the expedition had to overcome many obstacles by putting S. Gmelin’s life on the line.

Abstract This paper deals with the correspondence between Carl Heinrich Dreyer (1723–1802), the syndic of Lübeck, Germany, and Gerhard Friedrich Müller (1705–1783), Secretary of the Academy of Sciences in Saint Petersburg, Russia. The letters, written in 1761–1762, exhibit international cooperation in the scholarly study of medieval Hanseatic trade with Novgorod the Great. Dreyer’s letter accompanies his gift to the Academy of a thirteenth-century parchment document, a lesser-known copy of the famous treaty of 1269. This article discusses Dreyer’s membership of the Academy in connection to the prospects of further research cooperation. In addition, details of archival practice and aspects of scholarly morals are discussed against a background of ethical, historical and political issues of the day. As this article will demonstrate, some consequences of the described events and decisions can be connected to modern problems of historiography.

Hebrew incunabula amount to a rather modest, in terms of number, group of around 150 editions that were printed within the period from the late 60s of the 15th century to January 1, 1501 in Italy, Spain, Portugal and Turkey. Despite such a small number of Hebrew incunabula, the role they played in the history of the formation of European printing cannot be overlooked. Even less possible is to overestimate the importance of Hebrew incunabula for understanding Jewish spiritual life as it evolved in Europe during the Renaissance.Russian depositories house 43 editions of Hebrew incunabula, in 113 copies and fragments. The latter are distributed as following: the Institute of Oriental Manuscripts of the Russian Academy of Sciences — 67 items stored; the Russian State Library — 38 items; the National Library of Russia — 7 items; the Jewish Religious Community of Saint Petersburg — 1 item. The majority of these books came in public depositories at the late 19th — first half of the 20th century from private collections of St. Petersburg collectors: Moses Friedland (1826—1899), Daniel Chwolson (1819—1911) and David Günzburg (1857—1910). This article looks into the circumstances of how exactly these incunabula were acquired by the depositories. For the first time there are analysed publications of Russian scholars that either include descriptions of Hebrew incunabula (inventories, catalogues, lists) or related to various aspects of Hebrew incunabula studies. The article presents the first annotated bibliography of all domestic publications that are in any way connected with Hebrew incunabula, covering the period from 1893 (the first publication) to the present. In private collections, there was paid special attention to the formation of incunabula collections. It was expressed in the allocation of incunabula as a separate group of books in printed catalogues and the publication of research works on incunabula studies, which belonged to the pen of collectors themselves and haven’t lost their scientific relevance today.

This paper describes a history of friendship and collaboration between the astronomers N. Donitch and A.A. Baikov. Information on other astronomers L.V. Okulitch and E.A. Von der Pahlen, and meteorologists V.H. Dubinskii and Nina Gouma, can also be found. Details on the expeditions aimed at observing the total solar eclipses on 30 August 1905 (organized by the Imperial Academy of Sciences in Sankt-Petersburg) and 19 June 1936 (organized by the Romanian Royal Cultural foundation) are given. The main part represents the first English translation of the paper by Baikov, published earlier in Russian and Romanian, with a new preface, annotations, and comments.
