A later imitation of "Childe Harold’s Pilgrimage" lay unacknowledged for more than a century. John Clare had started to compose his own "Child Harold" in 1841, during the years of his madness, sometimes identifying himself as Byron, sometimes as a bigamist Byronic hero. Its intricate narrative stanzas are interspersed with many more lyrics than had been Byron's poem, often on the subject of Clare's youthful love for Mary Joyce. But, though "more sustained in thought than anything else he ever attempted", it was written piecemeal and the fragments were never unified or published until midway through the 20th century.
