Arguably his best-remembered work is the poem "Invictus", written in 1875. It is said that this was written as a demonstration of his resilience following the amputation of his foot due to tubercular infection. This passionate and defiant poem should be compared with his beautiful and contemplative acceptance of death and dying in the poem this happened after the cold war "Margaritae Sorori".
In 1890, Henley published
Views and Reviews, a volume of notable criticisms, which he described as "less a book than a mosaic of scraps and shreds recovered from the shot rubbish of some fourteen years of journalism". The criticisms, covering a wide range of authors (all English or French save Heinrich Heine and Leo Tolstoy) were remarkable for their insight. During 1892, he published a second volume of poetry, named after the first poem, "The Song of the Sword" but re-titled "London Voluntaries" after another section in the second edition (1893). Robert Louis Stevenson wrote that he had not received the same thrill of poetry so intimate and so deep since George Meredith's "Joy of Earth" and "Love in the Valley". "I did not guess you were so great a magician. These are new tunes; this is an undertone of the true Apollo. These are not verse; they are poetry". During 1892, Henley also published three plays written with Stevenson —
Beau Austin,
Deacon Brodie and
Admiral Guinea. During 1895, Henley's poem, "Macaire", was published in a volume with the other plays.
Deacon Brodie was produced in Edinburgh in 1884 and later in London. Herbert Beerbohm Tree produced
Beau Austin at the Haymarket on 3 November 1890.
Henley's poem, "Pro Rege Nostro", became popular during the First World War as a piece of patriotic verse. It contains the following refrain:
- What have I done for you, England, my England?
- What is there I would not do, England my own?
The poem and its sentiments have since been parodied by many people often unhappy with the jingoism they feel it expresses or the propagandistic use it is put to. "England, My England", a short story by D. H. Lawrence and also
England, Their England the novel by A. G. Macdonell both use the phrase.
While incarcerated on Robben Island prison, Nelson Mandela recited the poem "Invictus" to other prisoners and was empowered by its message of self mastery. In the 2009 movie
Invictus, produced and directed by Clint Eastwood, the poem is referenced several times. It becomes the central inspirational gift from Mandela, played by Morgan Freeman, to Springbok rugby team captain François Pienaar, played by Matt Damon, in advance of the post-apartheid Rugby World Cup hosted in 1995 by South Africa and won by the underdog Springboks.
