Shortly after Everett’s well-received remarks, Lincoln spoke for only a few minutes. With a “few appropriate remarks”, he was able to summarize his view of the war in just ten sentences.

Despite the historical significance of Lincoln’s speech, modern scholars disagree as to its exact wording, and contemporary transcriptions published in newspaper accounts of the event and even handwritten copies by Lincoln himself differ in their wording, punctuation, and structure. Of these versions, the Bliss version, written well after the speech as a favor for a friend, is viewed by many as the standard text. Its text differs, however, from the written versions prepared by Lincoln before and after his speech. It is the only version to which Lincoln affixed his signature, and the last he is known to have written.

Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.

Now we are engaged in a great civil war, testing whether that nation or any nation so conceived and so dedicated, can long endure. We are met on a great battle-field of that war. We have come to dedicate a portion of that field, as a final resting place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this.

In Lincoln at Gettysburg, Garry Wills notes the parallels between Lincoln’s speech and Pericles’s Funeral Oration during the Peloponnesian War as described by Thucydides. (James McPherson notes this connection in his review of Wills’s book. Gore Vidal also draws attention to this link in a BBC documentary about oration.
