Question: The carnival in the town where Jean Mathonet died is rooted in a European culture. In Rotrude's father's era, the language of that culture was later known by what name?

He played 13 times with the Belgian national team between 1952 and 1958. Jean Mathonet (6 October 1925, Bévercé, Malmedy – 22 October 2004, Malmedy) was a Belgian football player who finished top scorer of the Belgian First Division with 26 goals in 1956 while playing for Standard Liège. Mathonet made his international debut on Christmas 1952 in a 0–1 friendly win against France. <SEP> The Carnival of Malmedy is locally called Cwarmê. The celebration takes place during 4 days before the Shrove Tuesday. The Cwarmê Sunday is the most important and insteresting to see. Even if Malmedy is located in the east Belgium, near the German-speaking area, the Cwarmê is a pure walloon and Latin carnival. All the old traditional costumes parade in the street. The Cwarmê is a "street carnival" and is not only a parade. People who are disguised pass through the crowd and perform a part of the traditional costume they wear. The famous traditional costumes at the Cwarmê of Malmedy are the Haguète, the Longuès-Brèsses and the Long-Né. <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. 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. By the reign of Charlemagne, the language had so diverged from the classical that it was later called Medieval Latin. 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> Rotrude (or sometimes referred to as Hruodrud/Hruodhaid) (775/778 – 6 June 810) was a Frankish princess, the second daughter of Charlemagne from his marriage to Hildegard. <SEP> louis, duke of burgundy and later dauphin of france (16 august 1682 – 18 february 1712) was the eldest son of louis, grand dauphin, and father of louis xv, and briefly heir-apparent to the throne from his father's death in april 1711 to his own death 10 months later. until he became the official dauphin of france upon his father's death in 1711, he was known as le petit dauphin to distinguish him from his father, who was known as "le grand dauphin". his legitimate male progeny died out in 1883. <SEP> in argentina, the most representative carnival performed is the so-called murga, although other famous carnivals, more like brazil's, are held in argentine mesopotamia and the north-east. gualeguaychú in the east of entre ríos province is the most important carnival city and has one of the largest parades. it adopts a musical background similar to brazilian or uruguayan carnival. corrientes is another city with a carnival tradition. chamame is a popular musical style. in all major cities and many towns throughout the country, carnival is celebrated.
