A Walk Through Time - Ancient Calendars

Ancient civilizations relied upon the apparent motion of these bodies through the sky to determine seasons, months, and years. We know little about the details of timekeeping in prehistoric eras, but wherever we turn up records and artifacts, we usually discover that in every culture, some people were preoccupied with measuring and recording the passage of time. Ice-age hunters in Europe over 20,000 years ago scratched lines and gouged holes in sticks and bones, possibly counting the days between phases of the moon.

Five thousand years ago, Sumerians in the Tigris-Euphrates valley in today's Iraq had a calendar that divided the year into 30 day months, divided the day into 12 periods (each corresponding to 2 of our hours), and divided these periods into 30 parts (each like 4 of our minutes).

Historical Dictionary. World War II and the Holocaust. The Holocaust was the state-sponsored, systematic persecution and annihilation of European Jewry by Nazi Germany and its collaborators, between 1933 and 1945.

World War II and the Holocaust

Jews were the primary victims - six million were murdered. Roma (Gypsies), physically and mentally disabled people and Poles were also targeted for destruction or decimation for racial, ethnic, or national reasons. Millions more, including homosexuals, Jehovah's Witnesses, Soviet prisoners of war, and political dissidents also suffered grievous oppression and death under Nazi tyranny. The Nazi Party came to power in Germany in 1933.

The Nazis believed that Germans were members of a biologically "superior" race threatened with extinction through the struggle for survival with "inferior" races. Adolf Hitler moved to extend German power in central Europe, annexing Austria and destroying Czechoslovakia in 1938-1939. Germany invaded Poland in September 1939, beginning World War II.

By Tim Lambert Ancient Surgery In the stone age some adults had holes cut in their skulls.

A History of Surgery

At least sometimes people survived the 'operation' because the bone grew back. We do not know the purpose of the 'operation'. Perhaps it was performed on people with head injuries to release pressure on the brain. The Egyptians did have some knowledge of anatomy from making mummies. However Egyptian surgery was limited to such things as treating wounds and broken bones and dealing with boils and abscesses. They also knew that honey helped to prevent wounds becoming infected. A History of Baths and Showers. Most Tudors cared about their appearance.

A History of Baths and Showers

People carried mirrors made of glass or steel. They also carried combs and used tweezers, ear scoops and bone manicure sets. In the Summer people sometimes had a bath in the local river. Sometimes they heated a cauldron of water and had a strip wash. Or they could have a 'dry wash' by rubbing themselves with clean linen. In the 16th century bathrooms were very rare but Henry VIII had a bathroom in Hampton Court Palace. Livius. Articles on Ancient History. A History of Freedom of Thought.
