The Greek Myth:
In Greek legend Helen was the most beautiful woman in Greece and the indirect cause of the Trojan war. In legend, her parents were Zeus and either Leda or Nemesis. As a child she was kidnapped by Theseus but was saved by her brothers. As she grew up, she had suitors coming from all over Greece, and they all made a pact that after she chose someone, whoever it was, if something ever happened to her, they would all come together to fight for her. She chose Menelaus but but during an absence of him she was 'taken' by Paris and he took her to Troy, indirectly causing the start of the Trojan war. But when Paris was slain, she returned back to Sparta with Menelaus and lived happily until their deaths.
Tone of the Poem:
For me, the tone of the poem was sad. When I read it, it made me think of heartbreak, because there's this man who, fell in love with a woman who left and all he can think about is how much he wants her to come back and how she made him feel.
A modern allusion to the myth of Helen of Troy is the t.v. series that began in 2010 called Lost Girl. The series was about a girl who could 'suck' peoples souls. On the 4th line of the poem by Christopher Marlowe, he wrote, "Her lips suck forth my soul: see where it flies!". The allusion between these is that Helen supposedly "sucked forth"his soul, as can the girl in Lost Girl.
