10 years ago cipher-like stones started to emerge at random places in Bratislava, Slovakia´s capital. It took some time to find out who´s the author. Local artist, who also happen to be an art professor and academic sculptor, is the father of petrograms, as he calls them. Peter is his name and petros is the greek for stone. 

He used to distribute them in secret and tried to remain low-profile, but eventually was discovered by local enthusiasts. Now you can see a couple of them in local shop windows or wine cellar. Or if you´re lucky enough, you can find one yourself in the streets, cemeteries or parks of Bratislava. Or elsewhere in the world. And do they mean anything? That´s a mystery…
