Arthur, the disheveled former archaeologist turned Etruscan tomb-finder, is a man on a quest. When we first meet him, he is dreaming on a train heading home after being released from prison. Once home, he soon falls in with his old gang of tombaroli (grave-robbers) and they're on the search for treasure in the earth. For the rest of the gang, treasure means loot from Etruscan tombs; Arthur seems to be searching for something else. We get clues to Arthur's search in recurring images of a young woman and her red thread first seen in the opening shots of the film. The woman, we soon learn, is Beniamina, the daughter of Flora and Arthur's beloved. Flora lives in a crumbling palazzo with Italia, her singing student, and a group of women who call Flora mother. Italia is being exploited as a servant by Flora, who believes she is tone-deaf, but Italia in turn is raising two children in the house unbeknownst to Flora. The film juxtaposes these two kinds of groups: the rival groups of tombaroli led by men and the communal groups led by women (Italia forms the second group in a disused railway station), which echoes the remark early in the film that Italy would be much less macho today if the Etruscans had beaten the Romans rather than the other way around.
The film is full of mythic and historical resonances. Arthur is a latter-day Orpheus searching for his Eurydice (the first musical cue is from Monteverdi's Orfeo), but without Orpheus's gift of music. The red thread recalls Ariadne and the labyrinth. Flights of birds (and ominous pigeons) follow Arthur. Italia's first language is Portuguese and her children are of many ethnicities. And so on. In the hands of a lesser director or screenwriter this hybrid creature of different parts (you might call it a chimera) could have been a mess, but here everything seems to cohere and to create a mythic world that resembles our own, but is at an angle to it. That everything clicks into place so precisely and beautifully in the final scene is a tribute to just how tightly this loose-seeming film is constructed. Rarely have the loose threads of a plot been gathered with as much skill or in a more satisfying way.
Many of the photographic tricks (different film stocks, different aspect ratios, scenes undercranked) sound gimmicky, but, except for the undercranking, most are there for people who notice and transparent to those who don't. The cast is uniformly excellent.
For all its playfulness and its conceits, this moving, elegiac film tells the story of a great love and is a great love story.
