Soon lurid lights began to penetrate the vertical gallery which widened as we went up. Right and left I could see deep channels, like huge tunnels, out of which escaped dense volumes of smoke; tongues of fire lapped the walls, which crackled and sputtered under the intense heat.
Weldra drong een vale weerschijn in de wijder wordende loodrechte galerij; ik bespeurde links en rechts diepe gangen, gelijk aan onmetelijke tunnels, waaruit dichte dampen ontsnapten; vurige tongen lekten flikkerend hunne wanden.
