Guide dogs go back so far we are surprised when we look. Paintings from Herculaneum show blind people walking with dogs in 79 BCE. The idea was always there. And why not? Everything is in motion in this world and then the dogs come running to our sides. The dogs come rushing.
When the dog arrives, some peace comes. And a new brand of pertinacious strolling comes. Even in Herculaneum, a blind man walked to the village square, received water from a fountain, told a story about two snakes and an owl. And his oversized, white dog was pleased by the words. I saw it this morning in my own dog.
