While researching information for the publication of my 9th book The Flat Earth As Key To Decrypt The Book Of Enoch, I was led to understanding that not only does the Bible support premise that the earth is a flat circular plane but that it is covered by the firmament as a solid transparent dome like canopy. This led me to revisit the canonical and extra Biblical texts such as The Book Of Enoch, The Book Of Jasher, The Book Of Jubilees, and myriad others, to see if not only did they affirm such idea but if they contained other little known insight which might expound upon this matter in some detailed manner. This book is the end result of that search and compilation of all of those source references. And because I include in this study much extra Biblical material which few are familiar with, I doubt one will be able to find a more complete investigation of the firmament as topic than that which is presented here. The seeker of lost paradise may seem a fool to those whom have never sought the other worlds.
