Written privately on Byron's 36th birthday in his journal when preparing to join the Greek War of Independence.
Writes about his life, confronted by his own mortality. He expresses an importance in establishing a legacy.
Poem begins with speaker saying he is no longer loved, and this lack of love in his life makes him feel unable to love himself.
Ideas of the poem
Rejection of hedonism, nihilism, and the puer aeternus (mythology).
Hedonistic lifestyles lead to moral degradation, emotional isolation, and depression.
Can be interpreted as a philosophical poem.
Rhyme and Meter

Iambic tetrameter/iambic dimeter: short end line creates the feeling of the stanzas being cut short, suggests Byron's own life being cut short.
ABAB rhyme scheme, conveys Byron's conflicted state of mind.
Greek War of Independence
Greek war metaphorically represents Byron's own battle for freedom, fighting to be freed from society's views of him.
Suggests Byron has grown tired of his hedonistic lifestyle, and wants to use this war to redeem himself, possibly gaining a sense of honour.
"Still let me love!"
Theme of love: the lack of love creates a feeling of emptiness. Byron (or the speaker) has become bitter, which from his perspective makes his life pointless if he cannot love others.
Exclamation may suggest a sense of desperation and pleading, perhaps a hopeful tone as Byron is looking forward to the future and his willingness to change.
Shortened line emphasises Byron's growth and selflessness, shown by the desire to love another person.
"'Tistimethisheartshouldbeunmoved."

Sense of self-disgust and self-punishment, suggests the heart is unable to love or feel anything, it is "unmoved."
Conditional tense "should" implies the speaker wants to control his emotions as a form of atonement for the bad deeds in his lifetime/youth (hedonistic lifestyle).
"My days are in the yellow leaf;"
Abstract metaphor of "yellow leaf" conveys an image of autumn. Byron/speaker metaphorically compares his life to the seasons, representing the fact that he's slowly withering away and no longer youthful.
Link to Romantic idea of seeing man as an extension of nature's attributes.
"The flowers and fruits of Love are gone."
Extended metaphor represents the excitement and beauty of youth, the speaker enjoyed his life when he was young, whether his life was purposeful or not.
Capitalised "Love" may reflect its importance, link to "Still let me love!"
"flowers and fruits" shows Romantic imagery of nature, presenting its beauty and nurture.
"Love" is personified.
"The worm, the canker, and the grief."
Speaker combines destructive forces of nature ("worm" and "canker") and the cause of destruction in humans ("grief"). Suggests that the only things left for him relate to ageing and decay.
Repeated idea in Romantic poetry of the "worm" as a destructive force, symbolic for corruption, and biblical reference to the serpent.
"canker" = fungal plant disease, link to death and decay.
"The fire that on my bosom preys."
"Fire" as a metaphor for love, suggests it is a dangerous and destructive force, with "bosom" being close to heart emphasising this sense of danger.
Also a metaphor for sex, representing the speaker's/Byron's lost sexual passion once he aged and matured.
Animalistic imagery of "preys" further highlights love as a corrupting, dangerous, and predatory force.
Stanza 3 has a semantic field of cremation, possibly referencing Percy Shelley's cremation.
"The hope, the fear, the jealous care."
Asyndetic list of three abstract nouns, conveys an extreme range of emotions as Byron readies himself to go to war.
The speaker openly expresses these emotions and sees them as empowering.
Oxymoron of "jealous care" shows contradictory statements, perhaps reflecting the contrasts between older and younger, more free Byron.
"portion of the pain // And power of Love, I cannot share, // But wear the chain."
Plosive alliteration highlight the sense of pain and bitterness that love has caused for the speaker.
"I cannot share" links to the Romantic emphasis on the importance of individual experience, suggests a sense of loneliness and isolation.
"chain" as a metaphor for love showing a sense of restraint, imprisonment and lack of freedom. Speaker views love as a burden rather than something joyful due to his bitterness.
"The sword, the banner, and the field."
Militaristic language.
May perhaps reflect the Holy Trinity through synecdoches which symbolise war in an archaic manner.
Lack of conjunctions suggests the speaker's time is running out, Byron expects to die (ironic as Byron predicts his own death).
"Unworthy manhood!"
Self-hatred and criticism suggests guilt, or perhaps the speaker's recognition that he could have used his youthful years better.
May refer to fighting and dying honourably at war or conveying phallic imagery, alluding to Byron's sexuality.
"unworthy" suggests he feels unloved/unwanted.
Speaker may desire to redeem his manhood in the seemingly honourable act of war.
"If thou regrett'st thy Youth, why live?
Rhetorical question suggests the speaker thinks his hedonistic lifestyle was shallow and regrets the way he lived.
Through this Byron/the speaker argues that it is better to die for a noble cause than to continue living in a state of despair.
Dies in war = becomes noble and honourable, creating a legacy for himself in an attempt to erase his scandalous past.
"Then look around, and choose thy Ground, // And take thy rest."
"choose thy Ground" suggests Byron wanted to have a choice in his final days, to die an honourable death at war leaving behind the legacy he wanted to.
"choose" also suggests soldiers choose to die in battle, they have an active and glorified death for an honourable cause.
Link to Romantic ideas of freedom and the ability to make one's own decisions.
Dual meaning of "rest" being either relaxation or death.
