The phrase “A glooming peace this morning with it brings. The sun for sorrow will not show his head. ” it is spoken by the prince at the end of "Romeu e J *", after all the deaths caused directly or indirectly, by the enmity of the Capuleto and Monteschio families.
After the death of the two young people, the families showed how the enmity between them was malefic and ended up affecting the lives of those who just wanted to love, they then decide to end this enmity and make peace, in the name of those who are gone. The prince then affirms that that morning, it sealed peace between the families, but it was a dark, sad and melancholy peace, since it was necessary for a tragedy to happen for it to be sealed. This peace was so sad, that not even the sun celebrated it, but it hid, leaving the cold climate and showing the sadness in the hearts of the characters.
