12 and 13 provence in southern France was the center of knight lyric poetry. At first, these poems were sung by singers between the court and the assembly, and later they were widely circulated among the people. Its content has two aspects: one is to praise the heroic deeds of knights (Crusaders) and their joys and sorrows with their lovers. This is a song describing secular love, which means to show the pursuit of love freedom under the guise of church asceticism. The other is to praise Plato's love. This poem describes the lover's love in extremely beautiful and beautiful language, and praises the lover with words praising religion, God and the Virgin Mary. Young Dante's lyrics are deeply influenced by this writing method, and his praise for Bayar is the best of this kind of praise, which has been brought to the Divine Comedy.
