Barren Woman-Plath

Empty, I echo to the least footfall,
Museum without statues, grand with pillars, porticoes, rotundas.
In my courtyard a fountain leaps and sinks back into itself,
Nun-hearted and blind to the world. Marble lilies
Exhale their pallor like scent.

I imagine myself with a great public,
Mother of a white Nike and several bald-eyed Apollos.
Instead, the dead injure me with attentions, and nothing can happen.
The moon lays a hand on my forehead,
Blank-faced and mum as a nurse.

In this poem, plath calls herself an empty museum. 

 In the second stanza, she refers Nike and Apollo.

Plath has a few concepts involved in the poem... lilies  the moon, the concept of being full; hence -the crowded museum and the "great public."

But she never meets the great public. The museum remains empty. 

I don't get this line:

"Instead, the dead injure me with attentions, and nothing can happen."

The title speaks of a lonely woman, who possibly can't produce children (hence the name barren)

the imagery of the moon is a sexual concept. but the poem is so short, it could mean anything.
