R.U.R.

R.U.R. is a 1920 science fiction play by the Czech writer Karel Čapek. R.U.R. stands for Rossumovi Univerzální Roboti (Rossum’s Universal Robots). However, the English phrase Rossum’s Universal Robots had been used as the subtitle in the Czech original. It premiered on 25 January 1921 and introduced the word "robot" to the English language and to science fiction as a whole.

R.U.R. quickly became famous and was influential early in the history of its publication. By 1923, it had been translated into thirty languages.

The play begins in a factory that makes artificial people, called roboti (robots), out of synthetic organic matter. They are not exactly robots by the current definition of the term; these creatures are closer to the modern idea of cyborgs, androids or even clones, as they may be mistaken for humans and can think for themselves. They seem happy to work for humans at first, but that changes, and a hostile robot rebellion leads to the extinction of the human race. Čapek later took a different approach to the same theme in War with the Newts, in which non-humans become a servant class in human society.

Ziggurat of Ur

The Ziggurat (or Great Ziggurat) of Ur (Sumerian: é-temen-ní-gùru "Etemenniguru", meaning "temple whose foundation creates aura") is a Neo-Sumerian ziggurat in what was the city of Ur near Nasiriyah, in present-day Dhi Qar Province, Iraq. The structure was built during the Early Bronze Age (21st century BCE), but had crumbled to ruins by the 6th century BCE of the Neo-Babylonian period when it was restored by King Nabonidus.

Its remains were excavated in the 1920s and 1930s by Sir Leonard Woolley. Under Saddam Hussein in the 1980s, they were encased by a partial reconstruction of the façade and the monumental staircase. The ziggurat of Ur is the best-preserved of those known from Iran and Iraq, besides the ziggurat of Dur Untash (Chogha Zanbil). It is one of three well preserved structures of the Neo-Sumerian city of Ur, along with the Royal Mausolea and the Palace of Ur-Nammu (the E-hursag).

Sumerian ziggurat

The ziggurat was built by King Ur-Nammu who dedicated the great ziggurat of Ur in honour of Nanna/Sîn, in approximately the 21st century BCE (short chronology) during the Third Dynasty of Ur. The massive step pyramid measured 64 m (210 ft) in length, 45 m (148 ft) in width and over 30 m (98 ft) in height. The height is speculative, as only the foundations of the Sumerian ziggurat have survived.
