Crichton E M Miller FCILT, is a Fellow of the Chartered Institute of Logistics and Transport, he is a retired architect of Cloud platforms in logistics supply chains. His book The Golden Thread of Time https://www.ancient-origins.net/book-reviews/golden-thread-time-quest-truth-and-hidden-knowledge-ancients-0014538 follows his research which is focused on ancient astro navigation as a branch of Archaeoastronomy by non literate Neolithic and Bronze Age seafarers for the purposes of seasonal hunting and trading as part of early logistics and transport and evidenced in artefacts from considerable distances recently discovered in burial sites.. Seeking a simple instrument using wood, threads and plumb bobs, Crichton reverse engineered the "Sun Wheel symbol known popularily as “The Celtic Cross” in 1998 and 1999 as the only practical solution for taking spherical geometric observations in the prehistoric past and was granted two British patents as a working model proof of functionality and practicality and as an early forerunner of later quadrants, sextants and theodolites used for primitive astronomy, navigation and surveying . Crichton's original theory in 1998 was that seafaring and nomadic hunter gatherers and later traders utilised primitive astronomy for local timekeeping from manned watch stations and were potentially capable of taking into account calculations of the effects of axial precession, earths obliquity and lunar nodes . Reverse engineering the “Dixon Relics” found in the Pyramid of Khufu in 1872, he also seems to have resolved the methods of the priest Heminu at the time of the construction of the Necropolis at Giza. Since publishing his theory, support appears to be extant in the analysis of the Antikythera mechanism as a predictive astronomical almanac requiring preliminary observations that require a simple instrument capable of spherical geometry prior to the invention of trigonometry, proving that there is nothing new under the sun.
