Should you but fail at — Sea —

Should you but fail at — Sea —
In sight of me —
Or doomed lie —
Next Sun — to die —
Or rap — at Paradise — unheard
I’d harass God
Until he let you in!

Emily Dickinson

Mercury

If you should just fail at Sea —
In sight of me —
Or lie doomed —
To Die Next Sun —
Or rap at Paradise — unnoticed
I’d harass God
Until he let you in!

Mercury is the closest planet to Sun and observable at Sunset. So he is the loyal follower to Sun as well as Emily. She insists that God should open the Gate for him.
