have seen my head (grown slightly bald) brought in upon a platter
This stanza is made melancholy through careful references to death (the eternal footman who holds his cloaks) and even, in this allusion to getting your head chopped off simply because a girl asked for it. The man whose head came off was the prophet John the Baptist, and the girl was Salome, who, in the Bible, had no reason to want his head on a platter. However, Oscar Wilde gave reason to Salome's request by writing a book in which Salome is in love with John the Baptist, but he does not love her in return due to his love of God and fear of sins of the flesh. The reference to Oscar Wilde is perhaps more important due to the overarching theme in this poem that the lovers cannot love for some reason. http://www.mrbauld.com/exeliopru.html
