As he was easing himself back to mundane perceptions, Sam noticed a faint glow to one side of the entrance. With his worldly eyes, he saw a pictograph of a lizard where the flesh-and-blood lizard had clung to the rock. The red and ocher of the paint were bright and shiny and looked almost wet. It didn’t smell wet, though. When he touched one of the lines, Sam’s finger came away feeling damp but showing no sign of color. While pondering that mystery, he noticed another painting a meter or so higher. Faded, but recognizable, it was another lizard. Like the first, its head pointed toward the mouth of the cave. Now that Sam knew what to look for, he saw that the entire entrance was ringed with pictographs. All were lizards, and all pointed toward the cavern’s gaping mouth.
