Charon Crossing the River Styx was painted by Joachim Patinir between 1515 and 1524. A reproduction hangs on the wall of a bar in Málaga’s centro histórico where the detective protagonist of The Three-Headed Dog is often found. The original hangs in the Prado, which also plays a part in the book. The soul in the boat is shown in mid-voyage, at the point where a choice must be made between going to paradise (the hard route) or to Hell (the easy one).
In Greek mythology the dog Cerberus guards the gates of Hell for his master Hades, god of the underworld. One might expect the dog to trouble only souls trying to escape, but there is ambiguity in some sources about what he does to those trying to get in. Once you have a border you have to patrol it in both directions. Cerberus is Surveillance.
Cerberus has three heads. Some contemporary surveillance mechanisms don’t look so different. In the present day he is fences, walls, CCTV, infrared sensors, helicopters, planes and speedboats. Guards with binoculars and machine guns, checkpoints with Interpol databases, detention centres and sometimes, yes, sniffer dogs.
Surveillance against strangers must be one of the oldest human activities, when borders might indicate the territory of a family clan. Nowadays most controls don’t summarily shoot down intruders on sight, but the camps they get put into are sometimes a kind of living death.
Getting around Cerberus is the most urgent task of undocumented migrants. In The Three-Headed Dog a group of youngsters from the Caribbean have to get through border control with faked papers at Madrid’s Barajas Airport. The smuggler advises them how to finesse questions posed by border agents. Once past that point a long series of challenges begin as the migrants start trying to insert themselves into local life without drawing the notice of interior guard dogs. The border is never permanently crossed.
