Question: What was the form of the language that the last name Sylvester comes from, used in the era of the man crowned Roman Emperor in AD 800, later known as?

septimius severus (; ; 11 april 145 – 4 february 211), also known as severus, was roman emperor from 193 to 211. he was born in leptis magna in the roman province of africa. as a young man he advanced through the "cursus honorum"—the customary succession of offices—under the reigns of marcus aurelius and commodus. severus seized power after the death of emperor pertinax in 193 during the year of the five emperors. <SEP> Charlemagne's court in Aachen was the centre of the cultural revival sometimes referred to as the "Carolingian Renaissance". Literacy increased, as did development in the arts, architecture and jurisprudence, as well as liturgical and scriptural studies. The English monk Alcuin (d. 804) was invited to Aachen and brought the education available in the monasteries of Northumbria. Charlemagne's chancery—or writing office—made use of a new script today known as Carolingian minuscule,[M] allowing a common writing style that advanced communication across much of Europe. Charlemagne sponsored changes in church liturgy, imposing the Roman form of church service on his domains, as well as the Gregorian chant in liturgical music for the churches. By the reign of Charlemagne, the language had so diverged from the classical that it was later called Medieval Latin. An important activity for scholars during this period was the copying, correcting, and dissemination of basic works on religious and secular topics, with the aim of encouraging learning. New works on religious topics and schoolbooks were also produced. Grammarians of the period modified the Latin language, changing it from the Classical Latin of the Roman Empire into a more flexible form to fit the needs of the church and government. <SEP> Charlemagne (/ ˈʃɑːrləmeɪn /) or Charles the Great (2 April 742 -- 28 January 814), numbered Charles I, was King of the Franks from 768, King of the Lombards from 774 and Holy Roman Emperor from 800. He united much of Europe during the early Middle Ages. He was the first recognised emperor in western Europe since the fall of the Western Roman Empire three centuries earlier. The expanded Frankish state that Charlemagne founded is called the Carolingian Empire. <SEP> Auctor is Latin for author or originator. The term is used in Scholasticism for a "renowned scholar", and in biological taxonomy for the scientist describing a species or other taxon. The term is widely replaced by author in English-language works. <SEP> the roman legions first entered the area under decimus junius brutus in 137–136 bc, but the country was only incorporated into the roman empire by the time of augustus (29 bc – 19 bc). the romans were interested in galicia mainly for its mineral resources, most notably gold. under roman rule, most galician hillforts began to be – sometimes forcibly – abandoned, and gallaeci served frequently in the roman army as auxiliary troops. romans brought new technologies, new travel routes, new forms of organizing property, and a new language; latin. the roman empire established its control over galicia through camps (castra) as aquis querquennis, ciadella camp or lucus augusti (lugo), roads (viae) and monuments as the lighthouse known as tower of hercules, in corunna, but the remoteness and lesser interest of the country since the 2nd century of our era, when the gold mines stopped being productive, led to a lesser degree of romanization. in the 3rd century it was made a province, under the name gallaecia, which included also northern portugal, asturias, and a large section of what today is known as castile and león.
