as this but put it on the planet Mars.'". (See the Influences section on literary influences affecting the works's structure.) Chronicle structure The Martian Chronicles is written as a chronicle, each story presented as a chapter within an overall chronological ordering of the plot. Overall, the chronicle can be viewed as three extended episodes or parts, punctuated by two apocalyptic events. Events in the original edition of the book ranged from 1999 to 2026. As 1999 approached in real life, the dates in the book were advanced by thirty-one years in the 1997 edition. The summary that follows includes the dates of both editions. The first part covering two and a half years from January 1999/2030 to June 2001/2032 consists of seven chapters about four exploratory missions from the United States during which humans and Martians discover each other. The efforts of Martians to repel the human explorers ends in catastrophe when chicken pox brought to Mars by humans kills almost all Martians. Two of the chapters are original works for the fix-up. The second part covers four and a half years from August 2001/2032 to December 2005/2036 and consists of sixteen chapters in the first edition and seventeen in the 1997 edition. It is about the human colonizers of Mars, including human contact with the few surviving Martians, the preoccupation of the emigrants with making Mars like America on Earth, and the return of all settlers but seven to Earth as war on Earth threatens. All of the settlers are from the United States, and the settlements are administered by the United States' government. A global war on Earth ensues, and contact between Mars and Earth ends. Eleven of the chapters are original works for the first edition and thirteen for the 1997 edition. The third part, covering six months from April 2026/2057 to October 2026/2057, is three chapters about the remaining Martian settlers and the occurrence and aftermath of global nuclear war on Earth that eliminates human civilization there, and the few humans who manage to flee Earth and settle on Mars. None of the chapters are original works for the fix-up. Publication history The creation of The Martian Chronicles by weaving together previous works was suggested to the author by New York City representatives of Doubleday & Company in 1949 after Norman Corwin recommended Bradbury travel to the city to be "'discovered'". The work was subsequently published
