Navis Lusoria
A ''navis lusoria'' (, plural ) is a type of a small military vessel of the late Roman Empire that served as a troop transport. It was powered by about thirty soldier- oarsmen and an auxiliary sail. Nimble, graceful, and of shallow draft, such a vessel was used on northern rivers close to the ''Limes Germanicus'', the Germanic border, and thus saw service on the Rhine and the Danube. The Roman historian Ammianus Marcellinus mentioned the ''navis lusoria'' in his writings, but not much about it could be learned until the discovery of such boats at Mainz, Germany in 1981–82. The Roman ships of Mainz In November 1981, during excavation in the course of a construction of a Hilton Hotel at Mainz, wooden remains were found and identified as parts of an old ship. Before construction resumed three months later, the site yielded remnants of five ships that were dated to the 4th century using dendrochronology. The wrecks were measured, taken apart and, in 1992, brought to the Museum o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Keel
The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Etymology The word "keel" comes from Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work ''De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove, a suburb of Sydney, Australia, where careening was carried out ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Regensburg
The University of Regensburg (german: link=no, Universität Regensburg) is a public research university located in the medieval city of Regensburg, Bavaria, a city that is listed as a UNESCO World Heritage Site. The university was founded on 18 July 1962 by the Landtag of Bavaria as the fourth full-fledged university in Bavaria. Following groundbreaking in 1965, the university officially opened to students during the 1967–1968 winter semester, initially housing faculties in Law and Business Sciences and Philosophy.

Crossing Of The Rhine
The crossing of the Rhine River by a mixed group of barbarians which included Vandals, Alans and Suebi is traditionally considered to have occurred on the last day of the year 406 (December 31, 406). The crossing transgressed one of the Roman Empire, Late Roman Empire's most secure ''Limes (Roman Empire), limites'' or boundaries and so it was a climactic moment in the decline of the Roman Empire, decline of the Empire. It initiated a wave of destruction of Roman cities and the collapse of Roman civic order in northern Gaul. That, in turn, occasioned the rise of three usurpers in succession in the province of Roman Britain, Britannia. Therefore, the crossing of the Rhine is a marker date in the Migration Period during which various Germanic peoples, Germanic tribes moved westward and southward from southern Scandinavia and northern Germania. Ancient sources Several written accounts document the crossing, supplemented by the time line of Prosper of Aquitaine, which gives a fir ...

Alans
The Alans (Latin: ''Alani'') were an ancient and medieval Iranian nomadic pastoral people of the North Caucasus – generally regarded as part of the Sarmatians, and possibly related to the Massagetae. Modern historians have connected the Alans with the Central Asian Yancai of Chinese sources and with the Aorsi of Roman sources. Having migrated westwards and becoming dominant among the Sarmatians on the Pontic–Caspian steppe, the Alans are mentioned by Roman sources in the . At that time they had settled the region north of the Black Sea and frequently raided the Parthian Empire and the Caucasian provinces of the Roman Empire. From the Goths broke their power on the Pontic Steppe. Upon the Hunnic defeat of the Goths on the Pontic Steppe around , many of the Alans migrated westwards along with various Germanic tribes. They crossed the Rhine in 406CE along with the Vandals and Suebi, settling in Orléans and Valence. Around 409 CE they joined the Vandals and Suebi in cro ...

Suebi
The Suebi (or Suebians, also spelled Suevi, Suavi) 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. Although Tacitus specified that the Suebian group was not an old tribal group itself, the Suebian peoples are associated by Pliny the Elder with the Irminones, a grouping of Germanic peoples who claimed ancestral connections. Tacitus mentions Suebian languages, and a geographical "Suevia". The Suevians were first mentioned by Julius Caesar in connection with the invasion of Gaul by the Germanic king Ariovistus during the Gallic Wars. Unlike Tacitus he described them as a single people, distinct from the Marcomanni, within the larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vandal
The Vandals were a Germanic people who first inhabited what is now southern Poland. They established Vandal kingdoms on the Iberian Peninsula, Mediterranean islands, and North Africa in the fifth century. The Vandals migrated to the area between the lower Oder and Vistula rivers in the second century BC and settled in Silesia from around 120 BC. They are associated with the Przeworsk culture and were possibly the same people as the Lugii. Expanding into Dacia during the Marcomannic Wars and to Pannonia during the Crisis of the Third Century, the Vandals were confined to Pannonia by the Goths around 330 AD, where they received permission to settle from Constantine the Great. Around 400, raids by the Huns from the east forced many Germanic tribes to migrate west into the territory of the Roman Empire and, fearing that they might be targeted next, the Vandals were also pushed westwards, crossing the Rhine into Gaul along with other tribes in 406. In 409, the Vandals crossed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julian The Apostate
Julian ( la, Flavius Claudius Julianus; grc-gre, Ἰουλιανός ; 331 – 26 June 363) was Roman emperor from 361 to 363, as well as a notable philosopher and author in Greek. His rejection of Christianity, and his promotion of Neoplatonic Hellenism in its place, caused him to be remembered as Julian the Apostate in Christian tradition. A nephew of Constantine, Julian was one of few in the imperial family to survive the purges and civil wars during the reign of Constantius II, his cousin. Julian became an orphan as a child after his father was executed in 337, and spent much of his life under Constantius's close supervision.''Oxford Dictionary of Late Antiquity'', "Julian the Apostate", p. 839 However, the emperor allowed Julian to freely pursue an education in the Greek-speaking east, with the result that Julian became unusually cultured for an emperor of his time. In 355, Constantius II summoned Julian to court and appointed him to rule Gaul. Despite his inexperience, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germania Superior
Germania Superior ("Upper Germania") was an imperial province of the Roman Empire. It comprised an area of today's western Switzerland, the French Jura and Alsace regions, and southwestern Germany. Important cities were Besançon ('' Vesontio''), Strasbourg (''Argentoratum''), Wiesbaden ('' Aquae Mattiacae''), and Germania Superior's capital, Mainz (''Mogontiacum''). It comprised the Middle Rhine, bordering on the ''Limes Germanicus'', and on the Alpine province of Raetia to the south-east. Although it had been occupied militarily since the reign of Augustus, Germania Superior (along with Germania Inferior) was not made into an official province until c. 85 AD. Origin Initial Roman involvement The terms, "Upper Germania" and "Lower Germania" do not appear in the ''Commentarii de Bello Gallico'' of Julius Caesar, yet he writes about reports that the people who lived in those regions were referred to as "Germani" locally, a term used for a tribe that the Romans called the Germ ...

Mogontiacum
Mainz () is the capital and largest city of Rhineland-Palatinate, Germany. Mainz is on the left bank of the Rhine, opposite to the place that the Main joins the Rhine. Downstream of the confluence, the Rhine flows to the north-west, with Mainz on the left bank, and Wiesbaden, the capital of the neighbouring state Hesse, on the right bank. Mainz is an independent city with a population of 218,578 (as of 2019) and forms part of the Frankfurt Rhine-Main Metropolitan Region.

Castra
In the Roman Republic and the Roman Empire, the Latin word ''castrum'', plural ''castra'', was a military-related term. In Latin usage, the singular form ''castrum'' meant 'fort', while the plural form ''castra'' meant 'camp'. The singular and plural forms could refer in Latin to either a building or plot of land, used as a fortified military base.. Included is a discussion about the typologies of Roman fortifications. In English usage, ''castrum'' commonly translates to "Roman fort", "Roman camp" and "Roman fortress". However, scholastic convention tends to translate ''castrum'' as "fort", "camp", "marching camp" or "fortress". Romans used the term ''castrum'' for different sizes of camps – including large legionary fortresses, smaller forts for cohorts or for auxiliary forces, temporary encampments, and "marching" forts. The diminutive form ''castellum'' was used for fortlets, typically occupied by a detachment of a cohort or a '' centuria''. For a list of known castr ...

Rudder
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other vehicle that moves through a fluid medium (generally aircraft, air or watercraft, water). On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft), hull or fuselage, thus imparting a turning or yaw (rotation), yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize Drag (physics), hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical air ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
