A goat, two elephants, three monkeys, and one wolf.

This week, four new Banksy murals have appeared across London, prompting much speculation about their meaning.

The series began with a mountain goat on Monday, depicted in Banksy’s signature stencil style on a wall in Richmond, west London. The goat seems to be precariously perched on a ledge with rocks falling away.

Next, two elephant heads emerged on the side of a house in Chelsea, London, peering out from blocked windows. Following that, three monkeys were spotted hanging from a railway bridge near Brick Lane in east London.

On Thursday, a silhouette of a wolf howling at the sky appeared on a satellite dish atop a heavily graffitied building in Peckham, southeast London. Banksy has shared images of each mural on his Instagram account.

The satellite dish was reported stolen by London’s Metropolitan Police within hours of the mural’s unveiling. Local media captured images of it being removed by an individual wearing a mask.

The meaning behind these works has sparked various theories online. Banksy, known for addressing themes such as war and climate change in his art, has prompted speculation that these pieces could be commenting on recent riots and racist attacks across the UK or on the idea that humanity is driving its own downfall.

One Instagram user, “barrybrexiter,” suggested, “Nice one Banksy. I see this as a critique on the wild and chaotic behaviour currently erupting across the UK. Far-right thugs on the prowl.”

Another, “leticia_vega,” commented, “Humanity is not going to last … animals will be taking over.”

Banksy’s previous London mural, which featured green paint mimicking the foliage of a real tree, was interpreted as a commentary on the need to preserve nature. In December, another piece in Peckham depicted three drones on a stop sign and was stolen shortly after it appeared.
