What is the theme in On Location in the Loire Valley by Diane Ackerman?

Death in life is a theme. In a ghazal, the couplets can be read as selfcontained poems, so there may be a multiplicity of themes rather than one. Sometimes the first couplet sets the tone for the remainder, although that is by no means always the case. In this ghazal, the first couplet creates an image of life being gradually destroyed by a parasite (mistletoe), and yet beauty is present too. The mistletoe decorates the trees and lends enchantment to life. This description of a natural phenomenon may metaphorically suggest that even if life is always a journey to death and death is present in life, life is still worth living.
