Sticking around by the side of the road to paint a wall or the pillars of a passage is dangerous enough, but we found the most extreme form of graffiti yet, and it comes from Mexico. These guys are clearly risking life and limb to get their graffiti noticed.Is it worth it? Definitely not, as with no safety devices an accident is bound to happen. And it’s not like the motorists traveling at speed will be in the mood to “rear” their creations.Since we’re talking about graffiti, we had a small curiosity moment, wondering where it all started from. It turns out they have been around since ancient times, with examples dating back to Ancient Egypt, Ancient Greece, and the Roman Empire. Whether or not you agree with the modern urban art, graffiti is applied in art history to works of art produced by scratching a design into a surface.If you want to think of its historical meaning, then we should mention that the term graffiti referred to the inscriptions, figure drawings, and such, found on the walls of ancient sepulchers or ruins, as in the Catacombs of Rome or at Pompeii.All these clearly have little to no connection to how these “writing on the walls” are used nowadays. Often regarded as a way for artists to express underlying social and political messages, they continue to create disagreement amongst city officials, law enforcement and so on.Photos via AcidCow
