Stanza VII.—Line 358.
“The hollow blast of Süankos’ shell.”
The Süankos cannot properly be called a war instrument, although in the earlier ages of Persia, and even perhaps in Ismael’s time, it was made use of for that purpose. It is at present often used as a trumpet, for sounding an alarm, or a signal. Its tones are deep and hollow.
