XI Calypso[84] Salisbury, 1807 BEAUTIFUL CALYPSO—NORTHERN CALYPSO The generic name, _Calypso_, refers to the dedication of this genus to the Goddess Calypso. Its Greek signification is not only, as Salisbury wrote, to “cover and conceal” the stigma of the species, but also to preserve a poetical analogy between this botanical goddess, so difficult of access, and the secluded Goddess of Silence, whose Isle of Ogygia was fabled to be miraculously protected from observation by navigators.[85]
