Museums Deep in the Lava Rock

Five cave rooms sit inside dark rock veined with glowing lava, each one a small museum or workshop. At the top left, a bearded man shows a curiosity to an old woman in a fur-trimmed coat, among framed portraits, shoe cases and a glass counter of keys. Beside it, a man and a woman in a lab coat work a brass machine on a round stand under hanging question marks, with a chair, a clock and a stone umbrella pictured on the wall. Below left, two workers push a cart holding a clock and a small house while a third weighs rocks at a scale beneath paper volcanoes. In the centre, a miner and a visitor sort stones at a round table among crystals. At right, two cleaners wash a bronze statue in a tiled basin. Orange lava glowing between the chambers outlines every room, a fiery seam that is easy to follow.
