Image:  “Lincoln for the Defense” by Norman Rockwell 1961.  The image depicts Abraham Lincoln defending Duff Armstrong, charged with murder.  Lincoln is cross-examining the sole eye witness, Charles Allen, who testified about being able to see clearly at a distance of 150 feet in the middle of the night “by the light of the moon.”  Unfortunately for the witness, Lincoln had the Farmer’s Almanac and showed the jury that not only was the moon in the first quarter but it was riding “low” on the horizon, about to set, at the precise time of the murder. There would not have been enough light for Allen to identify Armstrong or anyone else, said Lincoln. The jury agreed, and Duff Armstrong was acquitted.
