On July 15, 1799, French Captain Pierre-Francois Bouchard finds the Rosetta Stone.

The Rosetta Stone is a granodiorite stele, inscribed with three versions of a decree issued at Memphis, Egypt in 196 BC on behalf of King Ptolemy V. The top and middle texts are in Ancient Egyptian using the Hieroglyphic script and the Demotic script, respectively, while the bottom is in Ancient Greek. As the decree had only minor differences between the three versions, the Rosetta Stone proved to be the key to deciphering Egyptian hieroglyphs.

The Rosetta Stone is a fragment of a larger stele; no additional fragments were found in later searches. Owing to its damaged state, none of the three texts is absolutely complete. This fragment of the stele is 3 feet 8 inches high at its highest point, 2 feet 6 inches wide and 11 inches thick. It weighs approximately 1,680 pounds. The front surface is polished smooth with the incised text; the sides are smooth; and the back is only roughly worked as this would not have been visible when erected.

The stone, carved in black granodiorite, similar to granite, is believed to have been originally in a temple, possibly at nearby Sais. It was moved during the medieval period, and was eventually used as building material in the construction of Fort Julien near the town of Rashid in the Nile Delta. During the Napoleonic campaign in Egypt, Pierre-Francois Bouchard discovered the stone and was immediately convinced of its importance. It was the first Ancient Egyptian bilingual text recovered in modern times; it aroused widespread interest with its potential to decipher previously untranslated hieroglyphic language.

Study of the decree was already under way when the first full translation of the Greek text appeared in 1803. It took another 20 years, however, before the transliteration of the Egyptian scripts was announced by Jean-Francois Champollion in Paris in 1822.  It took longer still before scholars were able to read the Ancient Egyptian inscriptions and literature confidently.

The major advances in the decoding of the Rosetta Stone were: The recognition in 1799 that the stone offered three versions of the same text; It became known in 1802 that the demotic text used phonetic characters to spell foreign names; Thomas Young recognized in 1814 that the hieroglyphic text did so as well, and had pervasive similarities to the demotic text; Champollion saw in his 1822-1824 studies that. in addition to being used for foreign names,  the phonetic characters were also used to spell native Egyptian words.

May 22, 1842 marks the discovery of Howe Caverns in New York state by Lester Howe and Henry Wetsel.

The Howe Caverns is a cave system in Schoharie County, New York. Geologists believe the formation of the cave, which lies 156 feet below ground, began several million years ago. The cavern is composed mainly of two types of limestone from different periods in the Earth’s early history, deposited hundreds of millions of years ago when the Atlantic Ocean stretched far inland. The cave is at a constant temperature of 52 degrees Fahrenheit, irrespective of the outside weather.

The Howe Caverns is named after farmer Lester Howe, who discovered the cave on May 22, 1842. Noticing that his cows frequently gathered near some bushes at the bottom of a hill on hot summer days, Howe decided to investigate. Behind the bushes, Howe found a strong, cool breeze emanating from a hole in the Earth. Howe proceeded to dig out and explore the cave with his friend and neighbor, Henry Wetsel, on whose land the cave entrance was located.

The cavern was open eight hours during the day for public tours in 1843. As the site became popular, a hotel was built over the entrance to the cave. From 1890 until the turn of the century, as visitors steadily decreased, a small community of management, quarry workers and their families sprang up in the hamlet now known as Howes Cave. While the Cave House Hotel had a steady business form 1871 to 1890, it eventually became a boarding house and later office space.

The rebirth and successful commercial development of Howe Caverns, as it is known today, between the years 1927-1929, is in large part attributable to two men, John Mosner of Syracuse and Walter H. Sagendorf of Saranac Lake. Mosner, an engineer, proposed the modern engineering developments that would make the cave easily accessible-even comfortable-to the average visitor. Mosner who was impressed by his visit to Howe’s Cave in 1890, believed that with a shaft for elevators sunk at the opposite end of the cave and the addition of electric lighting, Howe’s Cave would become a leading tourist attraction.

Sagendorf provided the organization for the Mosner plan; his brother John owned most of the land on which today’s Visitor Center is located. Howe Caverns, Inc. was organized as a closed stock corporation on October 11, 1927. Work began the next year under difficult conditions. The 156-foot elevator shaft was built at a cost of $1,100 per foot. A work force of well over 50 men constructed the walks and bridges and the above-ground facilities. The much-awaited grand re-opening of Howe’s Cave as Howe Caverns, Inc. took place on May 27, 1929. On the occasion more than 2,000 visitors toured what was once known as “Blowing Rock,” Lester Howe’s great wonder, down under.
