1. "She cannot fade, though thou hast not thy bliss,/ For ever wilt thou love, and she be fair!"
- This pair of lines portrays the eternal beauty and love on the urn, emphasizing a sense of everlasting innocence and purity.
2. "And, happy melodist, unweariéd, / For ever piping songs, for ever new;"
- These lines suggest a perpetual state of joy and creativity without weariness, capturing the essence of innocence through continuous happiness and renewal.
These lines highlight the theme of innocence by depicting timeless beauty, eternal love, joy, and unending creativity found on the Grecian urn, symbolizing a sense of purity and unblemished bliss.
