Sulphureous

Thy blazing hearths, / From deep sulphureous pits, consumeless stores / Of fuel boast.

The plain of Naples is the image of human passions; sulphureous and fertile; its dangers and its pleasures seem born of these fiery volcanoes, which give the air so many charms, and cause the thunderbolt to growl beneath our feet.

An excited and highly distempered ideality threw a sulphureous lustre over all.

The next morning I went to see the hot-springs and mud volcanoes, for which this place is celebrated. A picturesque path among plantations and ravines brought us to a beautiful circular basin about forty feet in diameter, bordered by a calcareous ledge, so uniform and truly curved, that it looked like a work of art. It was filled with clear water very near the boiling point, and emitted clouds of steam with a strong sulphureous odour.
