Archaeologia Baltica

The vallum in lacu (rampart by the lake) mentioned in 15th-century written sources as part of the Medieval landscape of Ostrowite (East Pomerania) has been researched by archaeologists and antiquaries since the 19th century. A wide range of noninvasive archaeological prospection methods were applied at Ostrowite in 2010-2015, including magnetic gradiometry, earth resistance, aerial photography, intensive field-walking, geochemical (phosphate) prospection, and the analysis of Airborne Laser Scanning. They were supplemented and verified by small-scale excavation work. This vast set of prospection methods was integrated into a Geographical Information System (GIS), and combined with an analysis of written sources, and allowed for the identification of a previously unknown ring-fort, which for the last 15 years has gone unnoticed by researchers conducting annual excavations in its vicinity. Its discovery and identification were only possible due to the integration of results from various methods, particularly non-invasive ones.

In this review of pollen data from the South Swedish uplands, evidence is presented of colonisation and strong agricultural expansion during the 11th to 13th centuries, followed by farm abandonment and land use change during the 14th to 15th centuries. The latter is associated with the Black Death and the late medieval crisis. Pollen data show that abandonment in the uplands resulted in the regrowth of woodland, but also in land use change from cereal growing to grazing. Similar cycles of agricultural expansion and decline are identified also from earlier periods during the Iron Age, which highlights the sensitive character of upland agriculture and settlement.

Viljandi (Fellin), a small town in medieval Livonia, was founded in the second quarter of the 13th century, soon after the Estonian Crusades. The Estonians’ prehistoric hill-fort was replaced by a castle of the Livonian branch of the Teutonic Order, the prehistoric settlement was abandoned, and the location for the new town was chosen on the site of a former field more suitable for fortification. In this paper, zooarchaeological material from three sites, the prehistoric settlement, the Order’s castle and the early medieval town, will be discussed. Despite the presumed changes in Estonian society associated with the Crusades, the analyses reveal no profound differences in meat consumption in the transitional period from prehistory to the middle Ages.

In the eighteenth century, the Abbé Lebeuf was a reknowned historian, a folklorist, a musicologist, and an archaeologist. He published several books and many articles in the Mercure de France. He was still famous in the 19th century but is now almost forgotten. His work contains a great many notes, reflections and other pieces of information of interest to those studying astronomy in culture. I present here a short selection of such fragments.

Since Clark and Stephenson (1977) proposed that the supernova remnant (SNR) G315.4-2.3 should be identified with the historical supernova (SN) seen by Chinese observers in the year A.D. 185, a great deal of work has been done by theoreticians and observers to test the hypothesis. Some authors have proposed the SNR G320.4-1.2 as a better candidate, while, on the basis of a reinterpretation of the Houhan-shu original text, even the very nature of the A.D. 185 event has been questioned, leading to the hypotheses of a cometary transit (Chin and Huang 1994) or a combination of Comet P/Swift-Tuttle and a nova (Schaefer 1995, 1996). In fact, a cometary transit was apparently registered in one of the Priscilla Catacomb frescoes, an ancient Roman artwork dating from the end of the second century. During our examinations of Roman Catacomb frescoes in an attempt to discover representations of “guest star” apparitions in Imperial Rome, we also discovered what seems to be a record of SN 369, indicating that this may have been the explosion which originated Cas A.
