O Parent, these are thy magnific deeds, Thy Trophies, which thou view'st as not thine own, Thou art thir Author and prime Architect: For I no sooner in my Heart divin'd, My Heart, which by a secret harmonie Still moves with thine, joyn'd in connexion sweet, That thou on Earth hadst prosper'd, which thy looks Now also evidence, but straight I felt Though distant from thee Worlds between, yet felt That I must after thee with this thy Son; Such fatal consequence unites us three: Hell could no longer hold us in her bounds, Nor this unvoyageable Gulf obscure Detain from following thy illustrious track.
