Famous quotes containing the word lineage:

    I declare
    Two lineages electrify the air,
    That will like pennons from a mast
    Fly over sleep and life and death
    Till sun is powerless to decoy
    A single seed above the earth:
    Lineage of sorrow: lineage of joy....
    Philip Larkin (1922–1986)
