   • 1839, Henry Wadsworth Longfellow, “Prelude”, in Voices of the Night, Cambridge, Mass.: […] John Owen, →OCLC, page xi:

     Therefore, at Pentecost, which brings
     The Spring, clothed like a bride,
     When nestling buds unfold their wings,
     And bishop's-caps have golden rings,
     Musing upon many things,
     I sought the woodlands wide.
