Merovingian script or Gallo-Roman script () was a medieval variant of the Latin script so called because it was developed in Gaul during the Merovingian dynasty. It was used in the 7th and 8th centuries before the Carolingian dynasty and the development of Carolingian minuscule. Script types There were four major centres of Merovingian script: the monasteries of Luxeuil, Laon, Corbie, and Chelles. Each script developed from uncial, half-uncial, and the Merovingian charter scripts. Luxeuil The Luxeuil type uses distinctive long, slim capital letters as a display script. These capitals have wedge-shaped finials, and the crossbar of ⟨a⟩ resembles a small letter ⟨v⟩ while that of ⟨h⟩ is a wavy line. The letter ⟨o⟩ is often written as a diamond shape, with a smaller ⟨o⟩ written inside. The letter ⟨a⟩ resembles two ⟨c⟩s ("cc"), and because of this distinctive feature the Luxeuil type is sometimes called "a type". The letter ⟨b⟩ often has an open bowl and an arm connecting it to the following letter, the letter ⟨d⟩ can have either a vertical ascender or an ascender slanted to the left; ⟨i⟩ is often very tall, resembling l; ⟨n⟩ can be written with an uncial form (similar to a capital ⟨N⟩); ⟨o⟩ is often drop-shaped and has a line connecting it to the next letter; and ⟨t⟩ has a loop extending to the left of its top stroke. The letter ⟨t⟩ is also used in numerous ligatures where it has many other forms. The letters ⟨e⟩ and ⟨r⟩ are also quite often found in ligature. Laon The Laon type has thicker display capitals than the Luxeuil type. Capital initial letters are often decorated with animals, and there are many ligatures with the letter ⟨i⟩. Like Visigothic script, there are two different ⟨ti⟩ ligatures, representing two different sounds ("hard" and "soft"). The letters ⟨d⟩ and ⟨q⟩ often have open bowls. The letter a is unique, resembling two sharp points ("<<"), and the letter ⟨z⟩, uncommon in Latin, is nevertheless very distinctive in the Laon type, with a flourish projecting upwards to the left, above the line. Because of these features, Laon type is sometimes called "a-z type". Corbie The Corbie type as used in the 8th century, was based on uncial and the Luxeuil type, but was also similar to half-uncial and insular script, with elements of Roman cursive. It is sometimes called "eN-type", as the letter ⟨e⟩ has a high,
