Claudius Ptolemy was an Alexandrian mathematician, astronomer, astrologer, geographer, and music theorist who wrote about a dozen scientific treatises, three of which were important to later Byzantine, Islamic, and Western European science. The first was his astronomical treatise now known as the Almagest, originally entitled Mathematical Treatise. The second is the Geography, which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika but more commonly known as the Tetrábiblos, from the Koine Greek meaning "Four Books", or by its Latin equivalent Quadripartite.
Scandinavia is a subregion of Northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. Scandinavia most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer to the Scandinavian Peninsula. In English usage, Scandinavia is sometimes used as a synonym for Nordic countries. Iceland and the Faroe Islands are sometimes included in Scandinavia for their ethnolinguistic relations with Sweden, Norway and Denmark. While Finland differs from other Nordic countries in this respect, some authors call it Scandinavian due to its economic and cultural similarities.
The Suebi were a large group of Germanic peoples originally from the Elbe river region in what is now Germany and the Czech Republic. In the early Roman era they included many peoples with their own names such as the Marcomanni, Quadi, Hermunduri, Semnones, and Lombards. New groupings formed later, such as the Alamanni and Bavarians, and two kingdoms in the Migration Period were simply referred to as Suebian.
The Rugii, Rogi or Rugians, were one of the smaller Germanic peoples of Late Antiquity who are best known for their short-lived 5th-century kingdom upon the Roman frontier, near present-day Krems an der Donau in Austria. This kingdom, like those of the neighbouring Heruli and Sciri, first appears in records after the death of Attila in 453. The Rugii, Heruli, Sciri and others are believed to have moved into this region from distant homelands under pressure from the Huns, and become part of Attila's Hunnic empire which also moved and came to be based in this region. The Rugii were subsequently part of the alliance which defeated Attila's sons and the Ostrogoths at the Battle of Nedao in 454, giving their kingdom independence. In 469 they were part of a similar alliance who lost to the Ostrogoths at the Battle of Bolia, weakening their kingdom significantly.
The Geats, sometimes called Goths, were a large North Germanic tribe who inhabited Götaland in modern southern Sweden from antiquity until the Late Middle Ages. They are one of the progenitor groups of modern Swedes, along with the tribes of Swedes and Gutes. The name of the Geats also lives on in the Swedish provinces of Västergötland and Östergötland, the western and eastern lands of the Geats, and in many other toponyms.
The Swedes were a North Germanic tribe who inhabited Svealand in central Sweden and one of the progenitor groups of modern Swedes, along with Geats and Gutes. They had their tribal centre in Gamla Uppsala.
Agder is a county and traditional region in the southern part of Norway and is coextensive with the Southern Norway region. The county was established on 1 January 2020, when the old Vest-Agder and Aust-Agder counties were merged. Since the early 1900s, the term Sørlandet has been commonly used for this region, sometimes with the inclusion of neighbouring Rogaland. Before that time, the area was considered a part of Western Norway.
Scandza was described as a "great island" by Gothic-Byzantine historian Jordanes in his work Getica. The island was located in the Arctic regions of the sea that surrounded the world. The location is usually identified with Scandinavia.
The German name of Austria, Österreich, derives from the Old High German word Ostarrîchi "eastern realm", recorded in the so-called Ostarrîchi Document of 996, applied to the Margraviate of Austria, a march, or borderland, of the Duchy of Bavaria created in 976. The name is seemingly comparable to Austrasia, the early middle age term for the "eastern lands" of Francia, as known from the written records.
The Charudes or Harudes were a Germanic group first mentioned by Julius Caesar as one of the tribes who had followed Ariovistus across the Rhine. While Tacitus' Germania makes no mention of them, Ptolemy's Geographia locates the Charudes (Χαροῦδες) on the east coast of the Cimbrian peninsula.
The Hilleviones were a Germanic people occupying an island called Scatinavia in the 1st century AD, according to the Roman geographer Pliny the Elder in Naturalis Historia, written circa 77 AD. Pliny's Scatinavia is generally believed to have referred to the Scandinavian peninsula, which in the 1st century AD had not yet been fully explored by the Romans and was therefore described as an island. Pliny wrote that it was an island "of a magnitude as yet unascertained". The Hilleviones lived in the only part of the island that was known, and according to Pliny, they thought of their 500 villages as a separate (alterum) world.
The Bateinoi or Batini were a Germanic tribe recorded by the Roman scholar Claudius Ptolemy. According to Ptolemy they were located "above" the Banochaemae tribe, who were settled near the upper Elbe, and "below" the Asciburgius mountain. That is all history knows for certain about them.
The Daukiones (Greek) or Dauciones (Latinization) were a Germanic tribe mentioned by Ptolemy (2.10) as living in Scandia, i.e. Scandinavia.
The Chaedini or Chaideinoi or Khaideinoi were a Germanic people that are listed only in the Geography of Ptolemy. He locates them in the west of a large island, Scandia, off the mouth of the Vistula river. Most scholars concur that Scandinavia is meant.
The Firaesi (Latinization) or Phiraisoi are a people listed in Ptolemy's Geography (2.10).
The Agri Decumates or Decumates Agri were a region of the Roman Empire's provinces of Germania Superior and Raetia, covering the Black Forest, Swabian Jura, and Franconian Jura areas between the Rhine, Main, and Danube rivers, in present southwestern Germany, including present Frankfurt, Stuttgart, Freiburg im Breisgau, and Weißenburg in Bayern. The only ancient reference to the name comes from Tacitus' book Germania. However, the later geographer Claudius Ptolemy does mention "the desert of the Helvetians" in this area.
The Nemetes were a tribe settled along the Upper Rhine by Ariovistus in the 1st century BC.
The Tencteri or Tenchteri or Tenctheri were an ancient tribe, who moved into the area on the right bank of the lower Rhine in the 1st century BC. They are known first from the surviving works of ancient authors such as Julius Caesar and Tacitus. In December 2015, archaeologists believed they found remains of the Tencteri in The Netherlands.
North Germanic peoples, Nordic peoples and in a medieval context Norsemen, were a Germanic linguistic group originating from the Scandinavian Peninsula. They are identified by their cultural similarities, common ancestry and common use of the Proto-Norse language from around 200 AD, a language that around 800 AD became the Old Norse language, which in turn later became the North Germanic languages of today.
The name of the Goths is one of the most discussed topics in Germanic philology. It is first recorded by Greco-Roman writers in the 3rd century AD, although names that are probably related appear earlier. Derived from Proto-Germanic *Gutōz ~ *Gutaniz, it is closely related to and probably means the same as the names of both the Geats of southern Sweden and Gutes of Gotland. The implications of these similarities, and the actual meaning of the Gothic name, are disputed in scholarship.
