Painted Murals And Frescoes Inside A Room At The Ancient Roman Ruins At Herculaneum (Ercolano), Campania, Italy
Located in the shadow of Mount Vesuvius, Herculaneum (Ercolano) was an ancient Roman town destroyed by volcanic pyroclastic flows in 79 AD. Its ruins are located in the commune of Ercolano, Campania, Italy.
As a UNESCO World Heritage Site, it is famous as one of the few ancient cities that can now be seen in much of its original splendour, as well as for having been lost, along with Pompeii, Stabiae, Oplontis and Boscoreale, in the eruption of Mount Vesuvius in AD 79 that buried it. Unlike Pompeii, the deep pyroclastic material which covered it preserved wooden and other organic-based objects such as roofs, beds, doors, food and even some 300 skeletons which were surprisingly discovered in recent years along the seashore as it was thought until then that the town had been evacuated by the inhabitants.
Herculaneum was a wealthier town than Pompeii, possessing an extraordinary density of fine houses with, for example, far more lavish use of coloured marble cladding.

Principles of Geology (1830)
Principles of Geology. Frontispiece (left) and title page (right) of volume one (1830) of 'Principles of Geology' by the British geologist Charles Lyell (1797-1875). This work established the principle that geological changes acting over long time periods have shaped the landscape. An example is shown in the frontispiece, which shows the columns of the Temple of Serapis at Puzzuoli, Naples, Italy. The dark bands about a third of the way up the columns are due to molluscs burrowing into the marble when volcanic activity lowered the land, evidence that sea levels have risen and fallen over time.

Cut surface of 500 MY old Durness Limestone marble
Marble. Cut surface of marble, a type of metamorphic rock derived from limestone. Pure marble consists only of the minerals calcite and dolomite, and is white. The colours here are caused by impurities of other minerals. Marble is formed when limestone is baked by intense heat and pressure, which cause the minerals in the rock to recrystallize into large, interlocking grains. The rock can be polished to a smooth, shiny surface and is easily worked, making it highly valued both in building and as a raw material for sculpture. This 500 million year old sample is from the Durness Limestone formation in Ledmore, Scotland, UK. Magnification x0.25 at 35mm size.
