During 1532 - 1555, 13th-generation Ikenobo priest Seno was regularly invited to the imperial court to arrange flowers and wrote 'Ikenobo Seno Kuden' (Ikenobo Seno's Book on Flower Arrangement) to comprehensively systemize the theory and technique of flower arranging.
天文(元号)年間（1532年-1555年）には、池坊13世専応が度々宮中に招かれて花を立て、また「池坊専応口伝」を表して立花の理論と技術を初めて総合的に体系化した。
