âGreen Caves sorcerers donât go to war,â said Ruth slowly. She looked suddenly frightened.
âSo why did Lady Ruth go?â Ted asked her.
Ellen snickered. âProbably because sheâs in love with Edward. You dress in menâs array, Ruthie, and quickly heal his wounds.â
âAnd you and Laurie can dress in menâs array and carry the bandages,â said Ruth, absently; she still seemed worried.
Chapter 5, The Hidden Land
This is an indirect reference to a traditional ballad sometimes titled Jack Monroe (Roud 268, Laws N7, c. 1818) â Dean is most likely referencing the version recorded by Steeleye Span, based purely on the specific turns of phrases quoted by Ellen and her other references to Steeleye Span renditions of traditional ballads.
In this quote, Ellen is very deliberately paralleling the language used in stanzas 4 and 9.
There was a wealthy merchant, in London he did dwell.
He had a beautiful daughter, the truth to you Iâll tell.
She had sweethearts a-plenty and men of high degree
But none but Jack the sailor her true love ere could be.
Jack heâs gone a-sailing with trouble on his mind
Heâs left his king and his country and his darling girl behind.
She went down to a tailorâs shop and dressed in menâs array
Sheâs signed a bill of passage to convey herself away.
Before you get on board, Sir, your name weâd like to know.
She smiled all in her countenance, they call me Jack-A-Roe.
I see your waist is slender, your fingers they are small.
Cheeks too red and rosy to face the cannonball.
I know my waist is slender, my fingers they are small,
But it would not make me tremble to see ten thousands fall.
The war soon being over she went and looked around,
Among the dead and wounded her darling boy she found.
She picked him up all in her arms and carried him to the town,
She sent for a physician who quickly healed his wounds.
This couple they got married, so well they did agree;
This couple they got married so why not you and me?
The ballad itself tells the story of a young woman who crossdresses and follows her forbidden lover to war, saving him from his wounds. The parallel is apt for the characters / actual Lady Ruth and Prince Edward, who are ostensibly pining for each other in a forbidden manner.
See Jackie Munro / The Wars of Germany / There Was a Wealthy Merchant for more information on the ballad itself and its variants.
