After the death of the Arian Emperor Valens, the synod of Antioch in 379 asked Gregory to help resurrect Constantinople to Nicene orthodoxy. While the most important churches were still headed by Arian bishops, Gregory transformed his cousin's villa into the Anastasia chapel. From this little chapel he delivered five powerful discourses on Nicene doctrine, explaining the nature of the Trinity and the unity of the Godhead. These are called the "Theological Orations." By the time he left Constantinople two years later, there did not remain one Arian church in all of the city.

“This book is the history of a proscribed and persecuted sect written by one of themselves,” writes Professor Edward Granville Browne, the Cambridge Orientalist who translated this narrative. “After suffering in silence for nigh upon half a century, they at length find voice to tell their tale and offer their apology. Of this voice I am the interpreter.” This work is the story of the life of the Siyyid ‘Alí-Muhammad-i-Shírází (1819-1850), known as the “Báb”, which is Arabic for “Gate”...

"The Light of Egypt" will be found to be an Occult library in itself, a textbook of esoteric knowledge, setting forth the "wisdom Religion" of life, as taught by the Adepts of Hermetic Philosophy. It will richly repay all who are seeking the higher life to carefully study this book, as it contains in a nutshell the wisdom of the ages regarding man and his destiny, here and hereafter. The London and American first edition, also the French edition, Vol. I, met with lively criticism from Blavatsky Theosophists, because it annihilates that agreeable delusion of "Karma" and "Reincarnation" from the minds of all lovers of truth for truth's sake.

Treatise on Light was published in 1690 and is probably the largest scientific volume on light published before Newton's Opticks. The book explains how light travels (i.e., that it has a certain velocity), and what happens when it hits a surface (refraction and reflection). A large portion of the book is devoted to the double refraction occurring in Iceland chrystal, and all drawn conclusions are proved geometrically. Christiaan Huygens (1629 - 1695) was a prominent physicist and astronomer. His main discoveries are the centrifugal force, collision laws for bodies and the argument that light consists of waves...

Prof. Hiram Bingham of Yale Makes the Greatest Archaeological Discovery of the Age by Locating and Excavating Ruins of Machu Picchu on a Peak in the Andes of Peru.There is nothing new under the sun, they say. That is only relatively true. Just now, when we thought there was practically no portion of the earth's surface still unknown, when the discovery of a single lake or mountain, or the charting of a remote strip of coast line was enough to give a man fame as an explorer, one member of the daredevil explorers' craft has "struck it rich...

Florence Augusta Merriam Bailey (August 8, 1863 - September 22, 1948) was an American ornithologist and nature writer. She started observing bird behavior at a time when most bird study was based on collections and skins. By 1885, she began to write articles focusing on protecting birds. Her introduction of a birdwatching field guide, aimed at living birds, is considered the first in the tradition of modern bird guides. She wrote the first of these at the age of 26, initially as a series of notes in the Audubon Magazine and later as books. In "A-Birding on a Bronco," she writes an engaging memoir about her several trips to study birds on a ranch in California in the late 1800's.
