terms refer to the language of the Franks prior to the advent of the High German consonant shift, which took place between 600 and 700 CE. After this consonant shift the Frankish dialect diverges, with the dialects which would become modern Dutch not undergoing the consonantal shift, while all others did so to varying degrees. As a result, the distinction between Old Dutch and Old Frankish is largely negligible, with Old Dutch (also called Old Low Franconian) being the term used to differentiate between the affected and non-affected variants following the aforementioned Second Germanic consonant shift. The Frankish language has not been directly attested, apart from a very small number of runic inscriptions found within contemporary Frankish territory such as the Bergakker inscription. Nevertheless a significant amount of Frankish vocabulary has been reconstructed by examining early Germanic loanwords found in Old French as well as through comparative reconstruction through Dutch. The influence of Old Frankish on contemporary Gallo-Roman vocabulary and phonology, have long been questions of scholarly debate. Frankish influence is thought to include the designations of the four cardinal directions: nord "north", sud "south", est "east" and ouest "west" and at least an additional 1000 stem words. Although the Franks would eventually conquer all of Gaul, speakers of Frankish apparently expanded in sufficient numbers only into northern Gaul to have a linguistic effect. For several centuries, northern Gaul was a bilingual territory (Vulgar Latin and Frankish). The language used in writing, in government and by the Church was Latin. Urban T. Holmes has proposed that a Germanic language continued to be spoken as a second tongue by public officials in western Austrasia and Northern Neustria as late as the 850s, and that it completely disappeared as a spoken language during the 10th century from regions where only French is spoken today. Art and architecture Early Frankish art and architecture belongs to a phase known as Migration Period art, which has left very few remains. The later period is called Carolingian art, or, especially in architecture, pre-Romanesque. Very little Merovingian architecture has been preserved. The earliest churches seem to have been timber-built, with larger examples being of a basilica type. The most completely surviving example, a baptistery in Poitiers, is a building with three apses of a Gallo-Roman style. A number of small baptistries can be seen in Southern France: as these fell out of fashion, they were not updated
