The Fundamental Principles of Old and New World Civilizations A Comparative Research Based on a Study of the Ancient Mexican Religious, Sociological, and Calendrical Systems
"The Fundamental Principles of Old and New World Civilizations" by Zelia Nuttall is a scientific publication written in the early 20th century. The work explores the comparative research of ancient Mexican religious, sociological, and calendrical systems, while examining connections with other early civilizations. Nuttall's study is focused on the origins and significance of symbology, particularly the swastika, and its representation across various cultures, especially in relation to celestial worship and cultural practices. At the start of the publication, Nuttall outlines her scholarly journey, beginning with her initial study of ancient Mexican manuscripts, which unexpectedly led her to broader comparative research of Old World and New World civilizations. She discusses how her investigations revealed striking similarities in the cosmological concepts held by various ancient cultures, particularly emphasizing the connection to pole-star worship and the foundational principles of societal organization rooted in astronomical observations. By establishing a dialogue between the cosmological ideas of the ancient Mexicans and those of cultures in the Old World, Nuttall lays the groundwork for an in-depth exploration of how these interconnected beliefs shaped the civilizations in both hemispheres.

"Our Calendar" by George Nichols Packer is a scholarly treatise on the history and mathematical principles of calendar systems, written in the late 19th century. The work delves into the transition from the Julian calendar to the Gregorian calendar, discussing the relevant historical reforms made by significant figures such as Julius Caesar and Pope Gregory XIII. Through detailed calculations and rules, Packer aims to simplify the complex processes involved in determining dates and understanding the calendar's structure, targeting those who seek a practical understanding of timekeeping. At the start of the book, the author introduces the topic by detailing the origin and evolution of the calendar. He emphasizes his personal journey through the subject, which began as a teaching endeavor and later grew into an extensive exploration prompted by his own circumstances. The opening chapters lay out definitions, the historical context of the Roman calendar, and the adjustments made under Julius Caesar and Pope Gregory XIII to correct discrepancies in timekeeping. Packer also hints at the mathematical rules that will follow, establishing a foundation for readers interested in not just the theoretical aspects but also the practical applications of calendar calculations in everyday life.
Emmeline M. (Emmeline Mary) Plunket
Ancient calendars and constellations
"Ancient Calendars and Constellations" by Emmeline M. Plunket is a historical account written in the early 20th century. The book explores the development of ancient calendars and their connection to constellations, particularly focusing on methodologies and observations made by ancient civilizations like the Babylonians and Assyrians. The central theme revolves around how these early systems of timekeeping are interwoven with astronomical knowledge and mythology. At the start of the book, the author provides a preface that outlines her intentions and the academic discussions that led to the assembled papers. These papers reference early astronomical research and argue for the significance of the Accadian calendar, suggesting that it may date back to around 6000 B.C. The opening portion elaborates on the complexities of ancient timekeeping and loss of seasonal alignment, presenting insights into how the various ancient cultures' calendars reflected their observations of celestial events and constellations. Plunket stresses the importance of this knowledge and how a deeper understanding of calendars can unveil connections with historical narratives and mythologies across civilizations.
