Kepler is a short history of events leading to the astronomical discoveries of Johannes Kepler. It was written by Walter William Bryant, a staff member of the Royal Observatory, Greenwich. The book was published in 1920 by the Society for Promoting Christian Knowledge, London, and by The MacMillan Company, New York, within a series of books called “Pioneers of Progress.”

Fridley is a city in Anoka County, Minnesota, United States. Its population was 29,590 at the 2020 census. It was first settled as a placed named Manomin where Rice Creek flows into the Mississippi river and the Red River Oxcart trail crosses the creek. Fridley was incorporated in 1949 as a village, and became a city in 1957. It is part of the Minneapolis–Saint Paul metropolitan area as a northern “first-ring” or “inner-ring” suburb. Most of the growth in Fridley occurred between 1950 and 1970. Fridley borders Minneapolis to the southwest. Neighboring first-ring suburbs are Columbia Heights to the south and Brooklyn Center to the west, across the Mississippi River.

In order to emphasise the importance of the reforms introduced into astronomy by Kepler, it will be well to sketch briefly the history of the theories which he had to overthrow. In very early times it must have been realised that the sun and moon were continually changing their places among the stars. The day, the month, and the year were obvious divisions of time, and longer periods were suggested by the tabulation of eclipses. We can imagine the respect accorded to the Chaldaean sages who first discovered that eclipses could be predicted, and how the philosophers of Mesopotamia must have sought eagerly for evidence of fresh periodic laws.

Soon after its publication Kepler’s “Epitome” was placed along with the book of Copernicus, on the list of books prohibited by the Congregation of the Index at Rome, and he feared that this might prevent the publication or sale of his books in Austria also, but was told that though Galileo’s violence was getting him into trouble, there would be no difficulty in obtaining permission for learned men to read any prohibited books, and that he (Kepler) need fear nothing so long as he remained quiet.
