The origin of the Seven Arts can be traced back to ancient Greece. The school of the wise has established three disciplines, namely grammar, rhetoric and dialectics. Plato identified four advanced subjects, namely arithmetic, geometry, music theory and astronomy. Educators after Greece have discussed these seven courses. In the 6th century AD, Cassidy Odorus, the abbot of the Abbey of Wavell, Italy, officially used the Seven Arts. This name re-emphasizes the seven-fold grouping of disciplines in his works, and connects it with the scripture in the Bible: "Building a house intelligently and supported by seven pillars", which gives a theological basis to the seven arts. Since then, the seven arts have constituted the normative content in education. The names of the Seven Arts in the Middle Ages are the same as those in ancient times, but their contents have changed greatly, especially after they became the main teaching contents of monasteries, they are full of theological contents. The study of seven arts mainly serves theological research. For example, learning grammar is reading the Bible; The purpose of studying rhetoric is to master the style of the Bible and cultivate the ability of propaganda and doctrine expression. Learning dialectics is used to debate and defeat pagans; Learning arithmetic means counting the dates of religious festivals and ceremonies, and even adding theological explanations to mathematical symbols. For example, "1" stands for the only god; "2" represents the dual character of Jesus' divinity and humanity; "3" stands for the Trinity of Father, Son and Holy Spirit; "4" stands for four evangelists and so on. Learning geometry can be used to design and draw patterns of church buildings; Learning music means playing music and singing hymns at religious ceremonies. The highest course in missionary schools is theology.
