But that which formed steps under our feet became stalactites overhead. The lava, which was porous in many places, had formed a surface covered with small rounded blisters; crystals of opaque quartz, set with limpid tears of glass, and hanging like clustered chandeliers from the vaulted roof, seemed as it were to kindle and form a sudden illumination as we passed on our way.
Mais ce qui se faisait marche sous nos pieds devenait stalactites sur les autres parois; la lave, poreuse en de certains endroits, présentait de petites ampoules arrondies; des cristaux de quartz opaque, ornés de limpides gouttes de verre et suspendus à la voûte comme des lustres, semblaient s'allumer à notre passage.
