Many have forgotten the role of the gosan in oral epic
literature. To believe that Persian poetics is only retelling what
they learned in a book is to hold that old accentual meter is
really newly borrowed from Arabic, which is hardly right. Dr.
Davidson has well explained this in her revised book.
