It was a landmark decision.

A Manhattan judge on Sunday ordered the Texas man accused of bashing the Financial District’s Charging Bull statue to “stay away from the landmarks in this city.”

“Do not go back and visit the bull,” Judge Althea Drysdale told accused bull bully Tevon Varlack during his arraignment in Manhattan Criminal Court Sunday.

Varlack, 42, wore a white t-shirt with the phrase “Let Us Not Forget The Ten Commandments” and appeared animated during his arraignment — even attempting to shake hands with a court officer.

Another inmate who spent the night in jail with Varlack said Sunday that the long-haul trucker continued his bizarre behavior behind bars, and “was up early singing gospel songs and preaching about God back in the cells. “

But he’s given no reason for the bizarre assault on the 3 1/2-ton statue.

In the Bible, Moses famously berated the Israelites when they began worshiping a statue of a golden calf while he was off receiving the Ten Commandments on Mt. Sinai.

Police said Varlack, a long-haul trucker, admitted when he was arrested Saturday that he took his metallic banjo and smashed the iconic bull, leaving a gash in one horn.

“I did it,” prosecutors said Varlack told officers during Varlack’s arraignment in Manhattan Criminal Court Sunday. “The banjo, the trumpet, and the speakers are mine.”

Prosecutors said three witnesses saw the Texan attack the bull in Bowling Green Park with the banjo, and said the office would seek restitution for the damage.

He was charged with criminal mischief, disorderly conduct and criminal possession of a weapon.

Drysdale released Varlack without bail and is due back in court on Oct. 16.

She said Varlack would have to figure out a way to get back to New York for that court date, and told him he would not qualify for a Legal Aid lawyer because he has a job.

Varlack had no comment as he ambled out onto Centre Street after the arraignment.

Meanwhile, statue creator Arturo Di Modica told The Post he believes Varlack attacked the statue to get his 15 minutes of fame.

“The guy wanted publicity and he did it for publicity,” the artist said. “He knew he was going to be arrested and he knew he was going to be in the paper. It wasn’t something that he wanted to hit the bull.”

Di Modica, who is out of the country, said he expects repairs to be completed by the time he returns to New York at the end of the month.

But he said “it’s a big job,” and estimated the damage at $10,000 to $15,000.

“The bull belongs to everybody, to the world,” he said. “In New York we must take care of it that nothing happens again.”
