There is, one knows not what sweet mystery about this sea, whose gently awful stirrings seem to speak of some hidden soul beneath...
Herman Melville, Moby Dick

Spend all your time waiting
For that second chance
For a break that would make it okay
There's always some reason
To feel not good enough
And it's hard, at the end of the day
Sarah McLachlan, Angel

Just to know we're safe, I am a grateful man
This light is pit, alive and I can see you clear
I could take your hand, and feel your breath
For feel that someday this will be over
I pull you close, so much to lose
Pearl Jam, Sirens

Angel, Sarah Mclachlan

In Greek mythology, the Sirens were dangerous creatures, who lured nearby sailors with their enchanting music and singing voices to shipwreck on the rocky coast of their island. Roman poets placed them on some small islands called Sirenum scopuli.

Sirens were believed to combine women and birds in various ways. In early Greek art, Sirens were represented as birds with large women's heads, bird feathers and scaly feet. Later, they were represented as female figures with the legs of birds, with or without wings, playing a variety of musical instruments, especially harps. The tenth-century Byzantine encyclopedia Suda says that from their chests up, Sirens had the form of sparrows, and below they were women or, alternatively, that they were little birds with women's faces.Birds were chosen because of their beautiful voices. Later Sirens were sometimes depicted as beautiful women, whose bodies, not only their voices, are seductive.
