Per Livingston Masonic Library, NYC: "The Ciphered Masonic Medal of the Netherlands; This medal was struck in 1825 at The Hague by the Grand Lodge of the Netherlands to commemorate the marriage of the Grand Master of Masons in the Netherlands, Prince Frederick of the Netherlands, to Princess Louise of Prussia. The medal was designed by Joseph-Pierre Braemt, a famous Belgian medalist & engraver. The obverse presents the female figure referred to as Latomia with ciphered lettering above translated as "Ornat Et Auget" which possibly means "Elegantly Increase in Wealth and Fertility" as a blessing to the royal couple.The reverse displays and radiated delta with the letter G , with ciphered inscription around which can be translated to "In Memoriam Augustissimarum Nuptiarum Fratum Libere Ac Fidelis Silenti Lege Operantium Florentissima In Belgio Societas." It could be roughly translated in English as "The most flourishing Society in Belgium of Brethren working freely under the law of faithful silence to commemorate the majestic wedding."On a side note, after the Napoleonic Wars in 1815, Belgium was annexed into the Kingdom of Netherlands, and so were the Belgian Lodges. It could possibly be that the Belgian Brethren, who were under The Grand Lodge of The Netherlands at that time, were the ones who issued this medal, which would explain why Belgium was mentioned on its inscription."1 3/4" bronze.
