GLORIA DEO PRINCIPIO
Glory to God; whose beginning is without beginning, and whose end is without end, to the Person who existed always before everything, who will be eternal after everything, and to Him whom sense or human reason does not attain, to know or recognise what He is.
And since he did not wish to remain for ever without manifesting Himself to men, He instructed the learned in His works and arts, so that the worker would be known from the works and the creator from the deeds, and therefore, it is fitting for the learned ones to whom He revealed His secrets to glorify Him above everything.
Therefore, let us here begin to examine the difficult, obscure questions of the ancients concerning the works, and in particular we discuss, with the help of the Creator of whom I speak, the characteristics of the firmament and of the four elements, and of their situation and their creation, with very just, forcible arguments and indisputable, irrefutable reasons and conclusions.
