Question: What was the language Auctor comes from during the era of Fastrada's spouse later known as?

<P0-S0> Auctor is Latin for author or originator. <P0-S1> The term is used in Scholasticism for a "renowned scholar", and in biological taxonomy for the scientist describing a species or other taxon. <P0-S2> The term is widely replaced by author in English-language works. <SEP> <P1-S0> Fastrada became the third wife of Charlemagne, marrying him in October 783 at Worms, Germany, a few months after Queen Hildegard’s death. <P1-S1> A probable reason behind the marriage was to solidify a Frankish alliance east of the Rhine when Charles was still fighting the Saxons. <SEP> <P2-S0> during the pre-columbian era of mesoamerican history, some mayan languages were written in the logo-syllabic maya script. <P2-S1> its use was particularly widespread during the classic period of maya civilization (c. 250–900). <P2-S2> the surviving corpus of over 10,000 known individual maya inscriptions on buildings, monuments, pottery and bark-paper codices, combined with the rich postcolonial literature in mayan languages written in the latin script, provides a basis for the modern understanding of pre-columbian history unparalleled in the americas. <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> from 1521, the spanish conquest of the aztec empire incorporated the region into the spanish empire, with new spain its colonial era name and mexico city the center of colonial rule. <P4-S1> it was built on the ruins of the aztec capital of tenochtitlan and became the capital of new spain. <P4-S2> during the colonial era, mexico's long - established mesoamerican civilizations mixed with european culture. <P4-S3> perhaps nothing better represents this hybrid background than mexico's languages: the country is both the most populous spanish - speaking country in the world and home to the largest number of native american language speakers in north america. <P4-S4> for three centuries mexico was part of the spanish empire, whose legacy is a country with a spanish - speaking, catholic and largely western culture.
