See the incredible photo.

A stormy day in Washington gave birth to a rare symbol of hope on Tuesday evening.

As the late Georgia congressman John Lewis laid in state at the U.S. Capitol Rotunda for one final night, a double rainbow appeared above the building.

WUSA9 reporter Mike Valerio managed to snap a photo of the twin rainbows that stretched across the top of the domed building where the beloved Civil Rights icon served for more than three decades.

"There's an EPIC double rainbow over the US Capitol and #JohnLewis right now, as he lies in state for 2 more hours..." Valerio wrote alongside the incredible photo on Twitter.

Lewis, the son of sharecroppers, died on July 17 after a six-month battle with pancreatic cancer. He was 80 years old.

The "conscience of Congress" arrived in DC on Monday following services in his hometown of Troy, Alabama, and a moving final crossing of the Edmund Pettus Bridge in Selma over the weekend.

Lewis' casket was escorted by a military honor guard to the center of the Capitol Rotunda, where he laid in state for two days. According to historians, he is the first Black lawmaker to lie in state at the US Capitol Rotunda. Thousands of mourners braved a record-breaking heat wave to pay their respects to the activist-turned politician known for making "good trouble"

Lewis arrived at the Georgia State Capitol on Wednesday, where he laid in repose until this morning, when he made his final journey to Ebenezer Baptist Church for a funeral attended by presidents Barack Obama, George Bush, Bill Clinton, and many of his colleagues from Congress.
