August 25 is the 237th day of the year (238th in leap years) in the Gregorian calendar. There are 128 days remaining until the end of the year.

On this day in 1768, James Cook began his first voyage to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. This would be the first of three voyages that would be hailed as  heroic by the scientific community.

In 1766, the Royal Society hired (James) Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. Cook was promoted to Lieutenant and named as commander of the expedition. The expedition sailed from England in 1768, rounded Cape Horn and continued westward across the Pacific to arrive at Tahiti  on 13 April 1769, where the observations were to be made. However, the result of the observations was not as conclusive or accurate as had been hoped. Cook later mapped the complete New Zealand coastline, making only some minor errors. He then sailed west, reaching the south-eastern coast of the Australian continent on 19 April 1770, and in doing so his expedition became the first recorded Europeans to have encountered its eastern coastline.

On 23 April he made his first recorded direct observation of indigenous Australians at Brush Island near Bawley Point, noting in his journal: “…and were so near the Shore as to distinguish several people upon the Sea beach they appear’d to be of a very dark or black Colour but whether this was the real colour of their skins or the C[l]othes they might have on I know not.” On 29 April Cook and crew made their first landfall on the mainland of the continent at a place now known as the Kurnell Peninsula, which he named Botany Bay after the unique specimens retrieved by the botanists Joseph Banks and Daniel Solander. It is here that James Cook made first contact with an Aboriginal tribe known as the Gweagal.

After his departure from Botany Bay he continued northwards, and a mishap occurred when Endeavour ran aground on a shoal of the Great Barrier Reef, on 11 June, and “nursed into a river mouth on 18 June 1770.” The ship was badly damaged and his voyage was delayed almost seven weeks while repairs were carried out on the beach (near the docks of modern Cooktown, at the mouth of the Endeavour River). Once repairs were complete the voyage continued, sailing through Torres Strait and on 22 August he landed on Possession Island, where he claimed the entire coastline he had just explored as British territory. He returned to England via Batavia (modern Jakarta, Indonesia), the Cape of Good Hope and the island of Saint Helena, arriving on 12 July 1771.

August 24 is the 236th day of the year (237th in leap years) in the Gregorian calendar. There are 129 days remaining until the end of the year.

On this day in 79 A.D., Mount Vesuvius erupted burying the cities of Pompeii and Herculaneum in nearly thirty feet of ash and pumice. The toxic gases killed at least 2200 people who remained in Pompeii after the evacuation.

After centuries of dormancy, Mount Vesuvius erupts in southern Italy, devastating the prosperous Roman cities of Pompeii and Herculaneum and killing thousands. The cities, buried under a thick layer of volcanic material and mud, were never rebuilt and largely forgotten in the course of history. In the 18th century, Pompeii and Herculaneum were rediscovered and excavated, providing an unprecedented archaeological record of the everyday life of an ancient civilization, startlingly preserved in sudden death.

At noon on August 24, 79 A.D., this pleasure and prosperity came to an end when the peak of Mount Vesuvius exploded, propelling a 10-mile mushroom cloud of ash and pumice into the stratosphere. For the next 12 hours, volcanic ash and a hail of pumice stones up to 3 inches in diameter showered Pompeii, forcing the city’s occupants to flee in terror. Some 2,000 people stayed in Pompeii, holed up in cellars or stone structures, hoping to wait out the eruption.

A westerly wind protected Herculaneum from the initial stage of the eruption, but then a giant cloud of hot ash and gas surged down the western flank of Vesuvius, engulfing the city and burning or asphyxiating all who remained. This lethal cloud was followed by a flood of volcanic mud and rock, burying the city.

The people who remained in Pompeii were killed on the morning of August 25 when a cloud of toxic gas poured into the city, suffocating all that remained. A flow of rock and ash followed, collapsing roofs and walls and burying the dead.

Plaster Citizens of Pompeii

Those that did not flee the city of Pompeii in August of 79 AD were doomed. Buried for 1700 years under 30 feet of mud and ash and reduced by the centuries to skeletons, they remained entombed until excavations in the early 1800s.

As excavators continued to uncovered human remains, they noticed that the skeletons were surrounded by voids in the compacted ash. By carefully pouring plaster of Paris into the spaces, the final poses, clothing, and faces of the last residents of Pompeii came to life.

n the only known eye witness account to the eruption, Pliny the Younger reported on his uncle’s ill-fated foray into the thick of the ash from Misenum, on the north end of the bay:

“. . .the buildings were now shaking with violent shocks, and seemed to be swaying to and fro as if they were torn from their foundations. Outside, on the other hand, there was the danger of failing pumice stones, even though these were light and porous; however, after comparing the risks they chose the latter. In my uncle’s case one reason outweighed the other, but for the others it was a choice of fears. As a protection against falling objects they put pillows on their heads tied down with cloths. ”

And then:

“You could hear the shrieks of women, the wailing of infants, and the shouting of men; some were calling their parents, others their children or their wives, trying to recognize them by their voices. People bewailed their own fate or that of their relatives, and there were some who prayed for death in their terror of dying. Many besought the aid of the gods, but still more imagined there were no gods left, and that the universe was plunged into eternal darkness for evermore.”
