Swallows

• Swallows are symbolic of hope through death - carrying souls to heaven.
• "the swallows are italic again" "between the telephone wires"

  Lexical field of writing/communication.
• "their script of descenders dipping their ink"

  Contradiction between permanency of ink on a page and the fleeting nature of birds (theme of erasure links to The Equation)
• "their annual regeneration"


  Migration of swallows - beginning again. Continuity in this annual activity.
• "that there is no seam/between parent and child"


  Enjambment reflects this. Continuity through the change of generations. Inherent beauty of nature.
