Boston’s skyline is about to get a little lonelier.

The mural of a man on a raft, hands in pockets, adrift in the sea of blue glass on the side of 200 Clarendon, will be removed starting Thursday. The French artist behind the installation, known as “JR,” tweeted the news Tuesday.

The mural, which mysteriously appeared in September on the skyscraper formerly known as the John Hancock Tower, spans the building’s 44th and 50th floors, measuring 150 feet wide and 86 feet tall.

Bryan Koop, executive vice president at Boston Properties, which owns 200 Clarendon, told the Globe in a statement that the mural was left up much longer than originally intended after the piece received rave reviews.

“The JR art installation was part of a temporary public art program and was initially planned to be on display for six weeks, which was extended to seven months due to positive feedback from the general public,’’ Koop said.

While he added that Boston Properties looks forward “continuing the conversation” on public art, no specifics were given regarding a new installation.
