Toward the end of the Muromachi period the earlier simple way of setting flowers in a vase developed into "tatehana" ("tateru", standing; "hana", flowers), a more complex style of ikebana. During this period the oldest extant manuscript of ikebana ("Kao irai no Kadensho", 1486) and the famous manuscript about ikebana by Ikenobō Senno (Senno Kuden, 1542) were written. Senno, the founder of Ikenobō kadō, originated ikebana that was imbued with meaning (kadō or way of flowers). Previously, tatehana had more of a connection to the spiritual practice of Yorishiro.
