The Baffled Knight
The Baffled Knight or Blow Away the Morning Dew is Child ballad 112 (Roud 11), existing in numerous variants. A version is recorded in Thomas Ravenscroft's Deuteromelia (1609) with a matching tune, making this one of the few early ballads for which there is extant original music.
A knight (or in later versions a farmer's son or a shepherd's son) meets a maid away from house and town, sometimes swimming in a brook. He proposes intimacy. She persuades him that they will be more comfortable upon her richly-appointed bed, or that if he brings her to her father's house, she will marry him and bring a rich dowry. When they arrive at her home she goes in first and locks him out; in most variants, once safely inside she taunts him for his gullibility.
The ballad generally includes advice to young men not be put off by maidenly protests when they meet defenseless women;
In one variant, he finds her again, and she tricks him by claiming her lover is near, so that he falls into the river, and a third time, in which she pulls his boots halfway off, so he is unable to get them on or off quickly enough to catch her.
