Monumental modern art doesn't come much more spectacular than this.

The finishing touches were being put Friday to a breathtaking installation about power by Chinese artist Huang Yong Ping which has a 133-ton snake threatening a triumphal arch made from shipping containers topped with a giant Napoleon hat.

It is easy to see "Empires" -- which opens to the public Monday -- as a metaphor for China's massive economic muscle dethroning the old great powers of the West.

But the artist best known for putting scorpions, tarantulas and other creepie crawlies in a glass case and letting them fight it out in his controversial "Theatre of the World", told AFP "there are several levels" to his enormous new show.

"It is about history, art and philosophy too," he insisted, saying that he also wanted it to have a wow factor for "the general public".

Curator Jean de Loisy said it is one of the most spectacular works ever shown in France's annual Monumenta show, when an artist is given free rein of the vast domed Grand Palais in Paris.

"Nothing has changed the world more in the last two decades than the Internet and shipping containers. They are the motors of global capitalism," he said.

"This show has an ambition that you will not see in many places in the world," said De Loisy, who runs the Palais de Tokyo modern art museum in the French capital.

He said the show confronted people with the enormity of the forces shaping our world.

- 'How small we are' -

"The moment you walk in you are faced by a huge cliff of containers, stacked seven high, which shows how small we are in relation to global industrial power," the curator said.

He said Huang had created a "complete symbolic landscape" with the giant skeleton of a 254-metre-long (833-feet) snake wrapping itself around the containers, with its fanged head menacing Napoleon's bicorne hat, an exact, scaled-up replica of the one he wore at the Battle of Eylau in 1807 when he was at the peak of his power.

"It was the battle that most shook Napoleon because of the huge number of dead," said De Loisy. "In that moment you sense the vulnerability of his supremacy."

The five-metre-high hat faces Les Invalides where the general is buried, and also lines up with the seat of French presidential power, the Elysee palace.

But it is clearly slipping from the top of its arch of containers, the curator pointed out, under the threat from the snake -- which he said symbolises change and the crushing power of capitalism.

- Game of mahjong -

"The snake with its aggressive head is the power of industry on the march, of geo-economic forces... China has made the choice of global economic power while America has made the choice of military might," De Loisy said.

He said Huang makes no "moral judgements" about the system which sees "containers making the great fortunes of the world but also providing a hiding place for the most unfortunate, the migrants who are smuggled in them.

"This ambivalence is crucial," he said. "We can do no more about the forces shaping our world in his view than you can about tectonic plates bumping up against each other or a volcano erupting."

Huang had also arranged the containers in a nod to the traditional Chinese board game of mahjong, he said.

"He feels the relationship between the West and China is also comparable to that between (the game of) Go and chess, symbolised by Napoleon's hat -- which is why we don't understand each other well enough."

Huang left China for France at the time of the Tiananmen protests in 1989. "Empires" runs until June 18.
