Byzantine Mosaic in the 6th Century of Italian Saint Vitalian's Church —— Ti odola and her maid. Since the 4th century, Byzantine poetry creation has entered a lasting development process. Gregory of Nisa, one of the "Three Masters of Capadocia" at that time, made the most outstanding achievements among many poets. His works are full of philosophy and strong thoughts, and are highly praised by people. The representative poet in the 5th century was Queen Docia. Her hymns brought fresh air to Byzantine poetry circles with their simple and innocent style. Moreover, due to her special status, under her influence, writing poetry and writing poetry has become a fad. Romanu is a representative figure of rhythmic poetry in the 6th century. He combined the stress system with the cadence of sentences and wrote thousands of conversational poems, which were catchy to read and very popular with people. Romanu's poems are very practical, because they can respond to duets and are accompanied by chorus, so they are often used in church ceremonies. Andrew (660 ~ 740), Bishop of Crete, also created a genre of lyric poetry that linked all kinds of rhythmic poems and opened up a new creative field for poets at all levels. Cassia (800 ~ 867), a nun who was only tall and beautiful in the 9th century, was a legend. She was famous for refusing the proposal of Emperor theophilus, and then devoted herself to the isolated monastic life, devoted herself to poetry creation, and created a poetic form full of pious feelings, occupying a place in the development of Byzantine poetry. Among the outstanding poets in the late Byzantine Empire, John Mao Soth (1000 ~ 108 1) and Theodore Medes (1270 ~ 1332) should be mentioned. Their poems show strong academic charm, which is very in line with the situation of reviving ancient cultural movement at that time.
The development of poetry directly promoted the progress of Byzantine music. The musical form of duet is developed from the poetic form in response to duet, while rhythmic poetry promotes the formation of scales 12 and 15, and musical forms such as stress, harmony and counterpoint are rapidly formed. Cappella, which is popular in Byzantine churches, has been maintained to this day, laying the foundation for the development of modern European music.
