Next major invention in mass communication was the invention of photography

Beatrice-1866 by Julia Margaret Cameron. The albumen print was invented in 1850 and was the most common type of print for the next 40 years. An albumen print was made by coating paper with a layer of egg white and salt to create a smooth surface. The paper was then coated with a layer of silver nitrate. The salt and silver nitrate combined to form light sensitive silver salts. This double coated paper could then be placed in contact with a negative and exposed to the sun to produce a print.

Papyrus, Parchment and Paper

Papyrus (from the plant papyrus) was used for writing in about 3000BC in Egypt.

Parchment or vellum (animal skin) was used about 150 BC, and continued to be used by the Christian monks in Europe in the Middle Ages. The original copy of the book of Kells is written on vellum.

Paper( mulberry tree bark, and bamboo pulp) was invented by the Chinese in 105 AD, developed further in Korea and then Japan( shortly after the arrival of Buddhism in Japan) in 610 AD, arrived in Samarkand and Baghdad along the Silk Rout in the 8th Century AD, and Europe by 1200's

Paper was widely used in Europe after the invention of printing by Gutenberg in 1452.

Phoenicia, 1000-200BC

Phoenicians spoke a Semitic language and lived along the coast of the Mediterranean Sea in today's Lebanon. They were conquered by the Persians ( Cyrus the Great in 539 BC), and later by Alexander the Great in 333BC. They were finally defeated by the Romans during the Punic wars (238) in Carthage in todays Tunisia.

Evolution of the main European and Semitic alphabets from the Phoenician alphabet

Click on this image to see how the Phoenician alphabet was adopted by the languages of Europe and the Middle East.

Phoenician alphabet was the basis of the European and the Semitic Alphabets

The phoenician alphabet was introduced about 1000 BC. Later Greeks copied the letters and some how modified them, and then the Romans created their alphabet based on the Greek alphabet. Semitic languages such as Hebrew, Arabic and Aramaic (Syriac) also based their alphabet on the Phoenician alphabet

Calligraphy and the art of Illumination in early Middle Ages

The book of Kells, the book of Durrow and the Lindisfarne Gospels are among the most beatiful Illuminated art from the early Middle Ages. In the next few pages I will be reflecting on the invention of alphabet, writing, papyrus, parchment and paper, invention of printing, photography and mass communications and the internet, as these ideas have profoundly affected the way we view the world.

The African continent and the Arabian Peninsula are clearly visible. Our ancestors left home in Africa for the Middle East about 100,000 years ago, and spread through all of the continents by 20,000 years ago.

Stonehenge

Stonehenge. Was used to see the arrival of the seasons, and may be to predict lunar eclipses. Stonehenge is about three thousand years old, and its astonomical significance was explored by Gerald Hawkins of Harvard-Smithsonian Observatory in the sixtees.

Fall Equinox

Today is the fall equinox. The length of the day is equal to the length of the night. Actually the path of the sun in the sky, from its rise in the morning to setting in the evening is exactly half way between its highest path in the summer and its lowest path in the winter. Roughly the highest path is on June 21st (summer solstice), and the lowest path is on December 21st (winter solstice). The equinox happens twice on September 21st and March 21st.

Our calendar is connected with the winter solstice, and the Jewish calendar is connected with the fall equinox. The Persian calendar is connected with the spring equinox. I am not aware of any modern calendar that begins with summer solstice.

Columbus discovering America
Salvador Dali-1959

Discovery of America, Salvador Dali

From the Dali Museum, St. Petersberg, Fl

"Dalí completed his tenth masterwork, The Discovery of America by Christopher Columbus, in 1959. This work, which is almost 14 feet tall, is an ambitious homage to Dalí's Spain, combining Spanish history, religion, art and myth. This painting was commissioned for Huntington Hartford's Gallery of Modern Art on Columbus Circle in New York. At that time, some Catalan historians claimed that Columbus was actually from Catalonia, not Italy. From that perspective, the discovery of America was all the more relevant for Dalí, who was himself Catalan. Dalí's inspiration for this work was a painting titled The Surrender of Breda by the great 17th century Spanish painter, Velazquez. Dalí repeated the image of spears from that painting on the right hand side of his work. Within these spears, Dalí painted the image of a crucified Christ, based on a drawing by the Spanish mystic Saint John. The banner that Columbus is holding bears the likeness of Dalí's wife, Gala. She appears as a saint, suggesting that she was Dalí's muse, and that she was responsible for his own "discovery of America," where he captured the attention of the world with her encouragement. The gadflies and the bishop at the bottom left are a reference to a Catalan folk legend about Saint Narciso. In this legend, on three occasions gadflies emerge from the tomb of St. Narciso to drive away French invaders. Dalí used this myth to underline the Catalan people's strength against foreign influence and to express his patriotic devotion to his homeland's independence. The most enigmatic element of all in this painting is a celestial sea urchin in the foreground. It was painted in the 1950s, and Dalí told the Morses that the sea urchin's meaning would only be apparent later. In the summer of 1971, Eleanor Morse remarked that Dalí had meant the urchin to symbolize the moon and Neil Armstrong's future first footstep on the moon. Through this symbolism, Dalí paralleled Armstrong's moon walk with Columbus's discovery of America, so that there was a clear continuity between the discovery of the "new world" in 1492 and the discovery of another "new world" in 1969.
