Question: What was the form of the language that the last name Sylvester comes from, used in the era of the king who united the 9th century tribes, later known as?

<P0-S0> later fresco replaced the more labor-intensive technique of mosaic in western-europe, although mosaics were sometimes used as decoration on medieval cathedrals. <P0-S1> the royal basilica of the hungarian kings in székesfehérvár (alba regia) had a mosaic decoration in the apse. <P0-S2> it was probably a work of venetian or ravennese craftsmen, executed in the first decades of the 11th century. <P0-S3> the mosaic was almost totally destroyed together with the basilica in the 17th century. <P0-S4> the golden gate of the st. vitus cathedral in prague got its name from the golden 14th-century mosaic of the last judgement above the portal. <P0-S5> it was executed by venetian craftsmen. <SEP> <P1-S0> The migration-period peoples who later coalesced into a "German" ethnicity were the Germanic tribes of the Saxons, Franci, Thuringii, Alamanni and Bavarii. <P1-S1> These five tribes, sometimes with inclusion of the Frisians, are considered as the major groups to take part in the formation of the Germans. <P1-S2> The varieties of the German language are still divided up into these groups. <P1-S3> Linguists distinguish low Saxon, Franconian, Bavarian, Thuringian and Alemannic varieties in modern German. <P1-S4> By the 9th century, the large tribes which lived on the territory of modern Germany had been united under the rule of the Frankish king Charlemagne, known in German as Karl der Große. <P1-S5> Much of what is now Eastern Germany became Slavonic-speaking (Sorbs and Veleti), after these areas were vacated by Germanic tribes (Vandals, Lombards, Burgundians and Suebi amongst others) which had migrated into the former areas of the Roman Empire. <SEP> <P2-S0> the first written evidence of deities in egypt comes from the early dynastic period (c. 3100–2686 bc). <P2-S1> deities must have emerged sometime in the preceding predynastic period (before 3100 bc) and grown out of prehistoric religious beliefs. <P2-S2> predynastic artwork depicts a variety of animal and human figures. <P2-S3> some of these images, such as stars and cattle, are reminiscent of important features of egyptian religion in later times, but in most cases there is not enough evidence to say whether the images are connected with deities. <P2-S4> as  egyptian society grew more sophisticated, clearer signs of religious activity appeared. <P2-S5> the earliest known temples appeared in the last centuries of the predynastic era, along with images that resemble the iconographies of known deities: the falcon that represents horus and several other gods, the crossed arrows that stand for neith, and the enigmatic "set animal" that represents set. <SEP> <P3-S0> Charlemagne's court in Aachen was the centre of the cultural revival sometimes referred to as the "Carolingian Renaissance". <P3-S1> Literacy increased, as did development in the arts, architecture and jurisprudence, as well as liturgical and scriptural studies. <P3-S2> The English monk Alcuin (d. 804) was invited to Aachen and brought the education available in the monasteries of Northumbria. <P3-S3> 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. <P3-S4> 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. <P3-S5> 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. <P3-S6> New works on religious topics and schoolbooks were also produced. <P3-S7> 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. <P3-S8> By the reign of Charlemagne, the language had so diverged from the classical that it was later called Medieval Latin. <SEP> <P4-S0> Sylvester is a name derived from the Latin adjective silvestris meaning ``wooded ''or`` wild'', which derives from the noun silva meaning ``woodland ''. <P4-S1> Classical Latin spells this with i. <P4-S2> In Classical Latin y represented a separate sound distinct from i, not a native Latin sound but one used in transcriptions of foreign words. <P4-S3> After the Classical period y came to be pronounced as i. Spellings with Sylv - in place of Silv - date from after the Classical period.
