==Book Content==


This manuscript tackles a diverse range of topics, demonstrating methods of astrological calculations and predictions that require prior knowledge in the field.


The entire manuscript was numbered by its author in terms of pages. It begins with some handwritten notes in English, explaining in detail how to use the perpetual calendar to calculate festivals and important dates of a year, including the date for Easter and for feasts (see photo 1.4). The first twelves pages of English notes are separated from the rest of the book, marked from “i” to “xii”. After the introductory notes, the manuscript officially begins on page “1”. Starting from this page, the writer turns to using Latin as the language of communication.

The writer then dedicates a large amount of time in the following pages to explain a fortune-telling technique that relies on numeric calculation. From page 1-55, the author creates many signature circle illustrations containing the alphabet of 26 letters (see photo 1.5). In these circles, each letter is assigned a number. The number is not fixed, but seems to be dependent on a case-by-case basis. The method of assigning numbers to letters is unknown. On every page that contains a signature circle illustration follows example calculations done by the author (see photo 1.6). The author demonstrates how to implement this method of numeric prediction, adding together the values assigned to each letter of a person's name.

There is a possibility that the book may have been rebound again by the collector or later readers. The patterns on the calf are delicately pressed and adorned with gilt. On the right side, there appear to be two metal locks, perhaps purposed for locking the content of the book away from common readers. Whether these locks were initially created to be functional or ornamental remains a question. If these locks were functional, they, in part, reflect the nature and history of astrological fortune-telling.

The methods and calculations for astrological predictions were largely exclusive to certain groups of people and not easily accessible. At its present stage, the metal locks do not appear to retain any particular purpose (i.e. locking up the text).  
Eventually, as the manuscript progresses, more elements are added to the circle, including archangels, the twelve horoscope signs, Latin phrases, and the classical planets (see photo 1.7). The simple circle illustrations, drew by delineating around a compass, developed into diverse, nuanced methods of calculating a person's lucky numbers. Though not any illustrations of these exact fashions could be discovered online, associations can be made between this manuscript and the work of earlier occultists such as [https://en.wikipedia.org/wiki/John_Dee John Dee] and [https://en.wikipedia.org/wiki/Johannes_Trithemius Johannes Trithemius], whose work also employs extensive numeric calculations, knowledge of Christian traditions, and a similar circle illustration pattern. This manuscript fits into a greater genre of astrological fortune-telling notebooks, purposed to compile together the centuries of astrological wisdom as well as adding in the author's personal touch and edits to the systems of calculation. The origin of these prediction methods cannot necessarily be traced back to one particular author, but can be attributed to the culmination of work done by astrology enthusiasts and knowledge passed down through the generations.


Beginning on page 56, the manuscript lists a calendar-like table with various signs representing the classical planets (see photo 1.8). A similar form is seen on page 64 where different numbers are also incorporated onto the table. The meaning and function of these tables remain rather elusive. It is interesting to note that at the top of the page, the author lists the names of four European languages: Dutch, French, English, and Latin. It could be possible that this manuscript was circulated among astrologers of different nations or royal courts. Another possibility could be that the author, who had added English introductions in the beginning of the manuscript, appropriated fortune-telling methods and astrological traditions from other European countries. The author could have set up the table in a way that it could be used by speakers of these four languages. Historically, in the Tudor Renaissance period, astronomical tables found in astrological manuscripts had to be adjusted to fit English use.<ref name="English Use"> Carey, Hilary M. “Henry VII’s Book of Astrology and the Tudor Renaissance.” Renaissance Quarterly 65, no. 3 (2012): 661–710. https://doi.org/10.1086/668299.</ref>


Within the table, numbers, the twelve horoscope signs, and the classical 12 planets were all mentioned. Depending on the page, sometimes, distinct black ink markings could be spotted. The ink markings are often times circles on numbers or corrections made to the numbers on the table. The ink color is very different from the brown ink in which the table was originally written and outlined. It could then be deduced that this manuscript successfully circulated among a group of people who have an in-depth understanding of astrological observations. Without a high-level understanding of this topic, authors of these marginalia would not be able to add onto each other's work.

Another reason the manuscript may be written and bound at different time periods is because of the marbled paper glued between the outer calf layer and the first page. This manuscript begins and ends with sheets of delicately-created marbled paper, consisting of deep red, sky blue, white, and light yellow oil colorings. This marbled paper is made in the nonpareil pattern, which was seen predominantly in 19th and 20th century. It may be suspected that the manuscript was first written in 1688, but later bound together into a notebook with a nice calf book cover by a collector, one or two centuries later. The date indicated on the title page clearly does not match that of the cover and the marbled paper.
Starting from page 70, the author starts drawing out patterns that appear to hold a lot of historical significance in the art of fortune-telling and astrology studies (see photo 1.9). On page 71, a sun and a phoenix being reborn in the fire were vividly depicted on the page. Christianity has traditionally taken meaning in [https://aleteia.org/2017/07/03/this-is-how-the-phoenix-became-a-christian-symbol/ phoenix], adopting it as a symbol of death and resurrection, sometimes used as a metaphor for the resurrection of Jesus Christ.

The manuscript continues to delve further into different techniques of fortune-telling throughout the rest of the book. Beginning on page 100, the author of the manuscript begins experimenting with a different form of calculation that depicts an octagon drawn inside a circle (see photo 2.1). This method seems to be relying on numeric calculations to find dates or numbers that correspond with various conditions of life. While most words remain hard to decipher, some Latin phrases could be translated to understand the illustrations. For example, on page 102, Latin words such as life, fortune, and health disclose the purpose of these circle illustrations. The author is using some form of numeric calculation to help predict the life path of various individuals.

Photo 1.1 Title Page, a calendar of the year 1688

Perpetual card: Vaticina Varia is a manuscript hand-written by an unknown author, detailing various fortune telling methods and astrological conventions. The name perpetual card means a perpetual calendar, sometimes also called an infinite calendar. This manuscript contains a calendar for the year of 1688, explanations on how to calculate the date for feasting and traditional holidays, as well as extensive examples and notes on astrological predictions. Perpetual card approaches the art of fortune-telling through numeric calculations, Christian traditions, and astrological observations. This manuscript was originally collected by the Henry Charles Lea Library, and now stored in theKislak Center for Special Collections, Rare Books and Manuscripts at the University of Pennsylvania.

Book Content

This manuscript tackles a diverse range of topics, demonstrating methods of astrological calculations and predictions that require prior knowledge in the field.

The entire manuscript was numbered by its author in terms of pages. It begins with some handwritten notes in English, explaining in detail how to use the perpetual calendar to calculate festivals and important dates of a year, including the date for Easter and for feasts (see photo 1.4). The first twelves pages of English notes are separated from the rest of the book, marked from “i” to “xii”. After the introductory notes, the manuscript officially begins on page “1”. Starting from this page, the writer turns to using Latin as the language of communication.

Photo 1.7 A circle illustration which includes numbers, planet signs, archangels

The writer then dedicates a large amount of time in the following pages to explain a fortune-telling technique that relies on numeric calculation. From page 1-55, the author creates many signature circle illustrations containing the alphabet of 26 letters (see photo 1.5). In these circles, each letter is assigned a number. The number is not fixed, but seems to be dependent on a case-by-case basis. The method of assigning numbers to letters is unknown. On every page that contains a signature circle illustration follows example calculations done by the author (see photo 1.6). The author demonstrates how to implement this method of numeric prediction, adding together the values assigned to each letter of a person's name.

Photo 1.8 A page with tables listing numbers, as well as four rectangles marking the four European languages: Latin, Dutch, French, English.

Eventually, as the manuscript progresses, more elements are added to the circle, including archangels, the twelve horoscope signs, Latin phrases, and the classical planets (see photo 1.7). The simple circle illustrations, drew by delineating around a compass, developed into diverse, nuanced methods of calculating a person's lucky numbers. Though not any illustrations of these exact fashions could be discovered online, associations can be made between this manuscript and the work of earlier occultists such as John Dee and Johannes Trithemius, whose work also employs extensive numeric calculations, knowledge of Christian traditions, and a similar circle illustration pattern.

The origin of these prediction methods cannot necessarily be traced back to one particular author, but can be attributed to the culmination of work done by astrology enthusiasts and knowledge passed down through the generations.

Beginning on page 56, the manuscript lists a calendar-like table with various signs representing the classical planets (see photo 1.8). A similar form is seen on page 64 where different numbers are also incorporated onto the table. The meaning and function of these tables remain rather elusive. It is interesting to note that at the top of the page, the author lists the names of four European languages: Dutch, French, English, and Latin.

Starting from page 70, the author starts drawing out patterns that appear to hold a lot of historical significance in the art of fortune-telling and astrology studies (see photo 1.9). On page 71, a sun and a phoenix being reborn in the fire were vividly depicted on the page. Christianity has traditionally taken meaning in phoenix, adopting it as a symbol of death and resurrection, sometimes used as a metaphor for the resurrection of Jesus Christ. It can thus be concluded that these methods of astrology are rooted in a Christian belief,[4] as well as the Greco-Roman traditions of gods and goddesses.
