The iconic painting Washington Crossing the Delaware is a misnomer. The river was actually modeled after the Rhine River in Germany, leading to several inaccuracies. According to Wikipedia:
“The river is modeled after the Rhine, where ice tends to form in jagged chunks as pictured, not in broad sheets as is more common on the Delaware. Also, the Delaware at what is now called Washington Crossing is far narrower than the river depicted in the painting.”
After this 1918 article, the original 1851 painting was destroyed in a 1942 bombing raid, as the original was housed in Germany. The two other versions also painted by Emanuel Gottlieb Leutze are still intact, currently housed at the Met in New York City and the Minnesota Marine Art Museum.
The painting was also parodied last month in Geico’s commercial Washington Crossing the Delaware Turnpike:
