as I have been learning about the historical traditions for calculating epacts, I have extracted the relevant equations. however, as one may observe, there are differing ‘techniques’ for calculating epacts. it is not immediately apparent to me which protocol the piece in question follows. once again, this will likely be resolved once I have translated the “ADMONITIONS” portion of the instructing text.

Keepsakes

Keepsakes   The Robe hanging on your door, was a holiday gift from your husband in 1964. The threadbare elbows and the seat is worn through, yet it was good enough to hang on to.   Why buy another when this has a few more years of life left in it.   Your Russian roots are all over the place, the perpetual calendar stopped sometime before 1999.   The crochet slippers you made but never gave to…

Perpetual Calendar

This instrument, made by Christian Boyling, consists of two superposed brass plates. The top plate is finely perforated and adorned with the coat of arms of the House of Saxony. We can glimpse a red silk backing

At the center of the plate is a circle divided into twenty-four hours containing three horary disks: a nocturnal based on the phases of the Moon, a perpetual calendar, and a zodiacal calendar showing the length of day and night throughout the year. Between the two plates is a rotating disk carrying twelve smaller enameled disks depicting the months (one missing). These appear one at a time through the small circular window below the three horary disks.

examining the instructions, particularly the details for determining the golden numbers and the Dominical letters, I have produced an approximate translation. while the translation is certainly not refined, it captures the essence of the knowledge needed to utilise the relevant information.

The shorter circle, whose title is "THE CIRCLE WHEREIN [are] THE GOLDEN NUMBERS", contains the golden numbers in the form of Roman numerals so arranged, as for the various Epacts of the centuries, and in the below cells is presented the letter of martyrology. These positions are to find, after the Epact is found, the golden numbers. However, the method to know these golden numbers is concise: The numbers of the year, of which you inquire, add a single unit, divide the resulting sum by 19, and what is left is the golden number of the same year. If there is nothing remaining, the golden number is 19. For example, 1746. Add 1. Divide the resulting sum by 19, and the remaining is 18, which is the golden number of the year 1746. So, the golden number will be in the cell below the position found by the Epact. And the purpose of the letter of martyrology, provided that the word corresponds with the INDEX by the hundredth.

For the Domincal Letters. To find the Domincal letter of each year is the same proportion, and in this manner the golden number. The number of which you inquire, add 9. Divide the resulting sum by 28, and for the remainder consult the first column of the table, whose title is "THE TABLE OF DOMINCAL LETTERS", which stands to the lower left side. And so, I say, the number will be shown exactly by the region of the year in question. However, if there is nothing remaining, it will be found from the area by the last number 28. For example, 1746. Add 9. Divide the resulting sum by 28, and the remaining is 19, the number in this case provided by the table, the letter of the year 1746, which will be the letter B. It must be observed, from the seven columns of the letters are arranged for the differing ages, which stands the hundredth.

of particular note, the bottom-most portion of the instructions appears to provide vital information for the broader use of the perpetual calendar as it contains details regarding information such as leap years. I have not yet translated this portion of the text but it is my next task.

The point of using promotional tools is to give you visibility as a business and bring you in the center of attention. The reason why so many brands and companies prefer using promotional items is to gain confidence of prospective customers, win them over and influence other people to join in along with them.
