BOCA RATON, Fla. — A 300-pound metal sculpture of a satanic pentagram, erected as an atheist protest to a public park’s Nativity scene, was severely damaged on Tuesday when it was pulled to the ground by vandals.

Atheist Preston Smith’s 10-foot tall sculpture lay broken in Sanborn Square at noon. Tire tracks led from the twisted metal to the street.

It appeared vandals had attached a chain from a vehicle to the sculpture and yanked it down, dragging it several feet. As local television reporters prepared live broadcasts, two passers-by stopped and pushed the sculpture back onto its base before walking away.

The sculpture sits about 20 feet from a traditional Nativity scene of Mary, Joseph and the baby Jesus, and is backed by a banner from an atheist group reading “Keep Saturn in Saturnalias,” a reference to the belief that the early Christian church substituted Christmas for a Roman pagan holiday.

It is the latest Florida protest against manger scenes on public property, mirroring earlier battles inside the state capitol in Tallahassee.

Boca Raton police officer Sandra Boonenberg said the overnight strike was the third attack on Smith’s sculpture and its explanatory banner since he erected the display earlier this month.
