“[Song into holiness]” is from Párados, a completed but still unpublished manuscript of more than sixty poems. Párados (πάροδος) is a byway, a side entrance—notable as the place where the chorus first enters and sings its first song. The eisodos (εἴσοδοι, plural) is another and privileged entrance. You might see these entrances by looking in Margarete Bieber’s The History of the Greek and Roman Theater, though I don’t remember that any of the diagrams she displays show the εἴσοδοι, and I think she will lead you into confusion over exodus and eisodos. Apart from her, all sources I know treat the entrances in the way I give here.”
