Calamus

( κάλαμος, a reed or cane). A haulm, reed, or cane. The term was applied to a variety of objects made out of reeds, such as a Pan’s pipe, a shepherd’s flute ( tibia ), a fishing-rod ( piscatio ), a rod tipped with lime, for fowling, . (See Arundo.) It was specially used, however, to denote a reed cut into proper shape, and used as a pen for writing.
