Solar eclipse

Index Solar eclipse

A solar eclipse (as seen from the planet Earth) is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and when the Moon fully or partially blocks ("occults") the Sun. [1]

Medes

The Medes (Old Persian Māda-, Μῆδοι, מָדַי) were an ancient Iranian people who lived in an area known as Media (northwestern Iran) and who spoke the Median language. At around 1100 to 1000 BC, they inhabited the mountainous area of northwestern Iran and the northeastern and eastern region of Mesopotamia and located in the Hamadan (Ecbatana) region. Their emergence in Iran is thought to have occurred between 800 BC and 700 BC, and in the 7th century the whole of western Iran and some other territories were under Median rule. Its precise geographical extent remains unknown. A few archaeological sites (discovered in the "Median triangle" in western Iran) and textual sources (from contemporary Assyrians and also ancient Greeks in later centuries) provide a brief documentation of the history and culture of the Median state. Apart from a few personal names, the language of the Medes is unknown. The Medes had an ancient Iranian religion (a form of pre-Zoroastrian Mazdaism or Mithra worshipping) with a priesthood named as "Magi". Later during the reigns of the last Median kings, the reforms of Zoroaster spread into western Iran.
