An undulating sky melds into the landscape, two silhouettes move along a balustraded walkway, and a ghostly figure's features extend in agony.
Since Norwegian artist Edvard Munch created "The Scream" in 1893, it's become one of the world's most famous artworks.
But why has its cry traveled so far and endured so long?
Munch was born in 1863, one of five children.
Tuberculosis devastated Europe throughout the 1800s, killing almost a quarter of all adults.
It took Munch's mother's life, then his elder sister's.
Soon after, Munch had his own bout of the disease.
Another of his sisters experienced mental illness and lived much of her life in an institution.
Meanwhile, Munch flitted in and out of school due to illness, often spending days at home, drawing and listening to the ominous stories his father read aloud.
A devout Lutheran, his father considered Munch's artistic ambitions unholy.
