Ancient Gaul was transformed during the reign of Augustus (r. 31 BC–14 AD) through a major programme of city building. The new Roman cities were constructed according to topographic, health and ritual considerations, and we hypothesise that their orientations also reflect distinct celestial conceptions held by the Gauls and by the Roman emperor

This book is a comprehensive reference on ancient Egyptian astronomy, one of the most important topics in historical astronomy. Written by two recognized specialists—one an astronomer trained in Egyptology and the other an Egyptologist trained in astronomy—it synthesizes and analyses the international body of research surrounding this ancient

In a recent Antiquity article, Darvill (2022) proposed that the mid third-millennium BC Stage 2 sarsen settings of Stonehenge (comprising the Trilithon Horseshoe, Sarsen Circle and the Station Stone Rectangle) were conceived in order to represent a calendar year of 365.25 days—that is, a calendar identical in duration to the Julian calendar. In the

We present the results of an analysis of the precise spatial orientation of colonial Christian churches located in the Canary Island of Fuerteventura (Spain). Our sample consists of 48 churches, most built during the period between the Castilian conquest led by the Norman Jean de Béthencourt in the early fifteenth century and the end of the

Measuring magnetic fields in the inner corona, the interface between the solar chromosphere and outer corona, is of paramount importance if we aim to understand the energetic transformations taking place there, and because it is at the origin of processes that lead to coronal heating, solar wind acceleration, and of most of the phenomena relevant

The study of dynamically cold stellar streams reveals information about the gravitational potential where they reside and provides important constraints on the properties of dark matter. However, the intrinsic faintness of these streams makes their detection beyond Local environments highly challenging. Here, we report the detection of an extremely
