Abjad Numerals in Arabic Manuscripts

Abjad numerals appear in many Arabic, Persian, Ottoman, and Islamic manuscript traditions. In manuscripts, Arabic letters were not only used as sounds. They could also work as numbers.

This is why a mark such as ا, ب, ج, or د may not always be part of the main text. In some manuscripts, it may be a folio number, a quire mark, a section marker, or part of a table.

This guide explains how Abjad numerals were used in manuscripts, how to recognize them, and why they matter for readers, catalogers, researchers, calligraphers, and students of Islamic manuscript culture.

For the complete letter-value table, see the Abjad table. For the broader historical system, read the Abjad Numerals Reference Encyclopedia. For special calculation issues, see Abjad calculation rules.

Quick Answer: How Were Abjad Numerals Used in Manuscripts?

Abjad numerals were used in manuscripts to mark numbers with Arabic letters.

Common uses included:

A reader who does not know Abjad values may mistake a number mark for a normal word or letter. A reader who knows Abjad can understand the manuscript structure more accurately.

What Is Foliation?

Foliation means numbering the leaves of a manuscript.

A folio is one leaf of paper. It has two sides:

In manuscript studies, foliation is not the same as pagination. A modern printed book usually counts pages. A manuscript often counts leaves. One folio has two sides, so one folio can contain two pages of writing.

For example:

In Arabic and Persian manuscript description, the front side is often marked as a, and the back side as b.

Why Abjad Foliation Matters

Abjad foliation helps readers understand the physical order of a manuscript.

This matters because old manuscripts may have:

A manuscript can preserve more than one numbering layer. One layer may come from the original scribe. Another may come from a later reader, owner, binder, librarian, or modern cataloger.

Basic Abjad Folio Marks

In simple foliation, early leaves may be marked with the first Abjad letters.

For larger numbers, the same system continues:

This page gives only the manuscript-focused examples. For the complete sequence, use the Abjad table.

Abjad Numerals vs Arabic Digits in Manuscripts

Arabic manuscripts may contain more than one number system.

A manuscript might have Abjad foliation from an earlier stage and Western pencil numbering from a modern library. These two systems do not always agree.

When they disagree, do not assume one is automatically wrong. Each numbering layer may describe a different stage in the manuscript’s history.

Abjad Numerals and Quire Numbering

A quire is a gathering of folded sheets. Several folded sheets are stacked together, then sewn into the manuscript.

Quire numbering helped scribes and binders keep the manuscript in the correct order.

A quire may be marked with Abjad letters so the binder knows the sequence:

This was practical. If a manuscript was copied in sections, stored before binding, or repaired later, quire marks helped preserve the intended order.

Quire Marks vs Folio Numbers

Quire marks and folio numbers are not the same.

A single Abjad letter at the start of a gathering may not be a folio number. It may be a quire mark.

Where Abjad Marks Usually Appear

Abjad marks may appear in different places depending on the manuscript, region, date, and later handling.

Common locations include:

The same mark can mean different things depending on where it appears. Context matters.

Catchwords and Abjad Marks

A catchword is a word written at the bottom of a page that repeats the first word of the next page.

Catchwords helped keep leaves in order. They are not the same as Abjad numerals, but both can help reconstruct manuscript sequence.

A manuscript may use both catchwords and Abjad marks. When both agree, the order is easier to confirm. When they disagree, the manuscript may have been damaged, rebound, or renumbered.

Abjad Marks in Prefaces

Some Arabic printed books and manuscript-style works use Abjad letters to number preliminary pages.

This is similar to how English books may use Roman numerals for front matter, such as i, ii, iii, and iv, before the main page numbering begins.

In this use, Abjad numbers may appear before the main text starts.

For example:

This helps separate the introduction, preface, table of contents, or editor’s notes from the main body.

Abjad Marks in Tables

Abjad numerals also appear in tables, especially in scientific, mathematical, astronomical, medical, and technical manuscripts.

A table may use letters as numbers because the reader was expected to know the Abjad values.

This can appear in:

A modern reader may mistake a table value for text if the Abjad system is not recognized.

Example: A Manuscript with Multiple Numbering Systems

Some manuscripts contain more than one foliation system.

A manuscript may have:

This is one reason manuscript descriptions often include notes about foliation problems.

A catalog entry may say that a manuscript is foliated in both Arabic numerals and Abjad letter-numerals, but that the systems do not align toward the end. That type of note is important because it warns readers not to rely blindly on one numbering layer.

Common Problems with Abjad Foliation

Abjad foliation can be difficult to read for several reasons.

For difficult cases, compare Abjad marks with the manuscript’s physical structure, catchwords, text continuity, and catalog notes.

Reading Abjad Foliation Step by Step

Use this process when studying a manuscript:

1. Identify whether the mark is a letter, digit, word, or later pencil number.
2. Check where the mark appears on the leaf.
3. Compare it with the marks on nearby leaves.
4. Convert the Abjad letter into its numerical value.
5. Check whether the sequence increases normally.
6. Compare the sequence with catchwords, section starts, and text continuity.
7. Look for missing, repeated, or later-added numbers.
8. Record uncertainty instead of forcing a clean sequence.

This method is safer than treating every visible mark as original.

How to Tell If a Mark Is a Number or Text

Not every Arabic letter in a margin is an Abjad number.

Ask these questions:

A reliable reading depends on physical context, not just the letter itself.

Why Abjad Foliation Can Conflict with Modern Numbers

Modern library numbering often happens after the manuscript has already lived through centuries of use.

By that time, the manuscript may have been:

This creates layered evidence. The older Abjad marks may show one stage of the manuscript. The modern pencil numbers may show how the manuscript is currently arranged.

Both can be useful.

Abjad Foliation and Cataloging

Manuscript catalogers often describe foliation carefully because it affects references to the text.

A catalog entry may include:

This helps researchers cite the manuscript accurately.

How to Cite a Manuscript Folio

When citing a manuscript, use the folio reference given by the catalog or library.

Examples:

Do not convert a manuscript folio into a page number unless the catalog uses page numbers. Folio references and page references are not the same.

Frequently Asked Questions

What are Abjad numerals in manuscripts?

Abjad numerals in manuscripts are Arabic letters used as numbers. They may mark folios, quires, sections, tables, or dates.

What is Abjad foliation?

Abjad foliation is the numbering of manuscript leaves using Abjad letter values instead of modern digits.

What is the difference between foliation and pagination?

Foliation counts leaves. Pagination counts pages. One folio has two sides, usually described as a and b in Arabic and Persian manuscript cataloging.

What is a quire in a manuscript?

A quire is a gathering of folded sheets. Quires were sometimes numbered so that the manuscript could be assembled in the correct order.

Are Abjad quire marks the same as folio numbers?

No. A quire mark usually identifies a group of leaves. A folio number identifies a single leaf.

Why do manuscript numbers sometimes disagree?

Different numbering systems may have been added at different times. A manuscript may contain Abjad marks, Arabic digits, Western pencil numbers, and later catalog numbers.

Can Abjad foliation prove the original order of a manuscript?

It can help, but it is not always final proof. The reader should also check catchwords, text continuity, binding structure, missing folios, and catalog notes.

Are Abjad numerals still used in manuscript cataloging?

Modern cataloging usually uses standard folio references, but catalogers still record older Abjad numbering when it appears in the manuscript.

How do I convert an Abjad mark into a number?

Use the standard Abjad table. For example, ا = 1, ب = 2, ج = 3, د = 4, ي = 10, ك = 20, ق = 100. For the full table, see the Abjad table.

Can software detect Abjad numerals automatically?

Some digital humanities work studies automatic recognition of Abjad numerals, but manuscript context still matters because the same Arabic letter can be either text or a number.

Conclusion

Abjad numerals are an important part of Arabic manuscript culture. They were used to mark folios, quires, preliminary pages, tables, sections, and sometimes dates.

For manuscript readers, Abjad marks are not just historical decoration. They can help identify missing leaves, repeated folios, binding problems, older numbering layers, and the relationship between manuscript structure and catalog records.

The safest approach is to read Abjad marks in context. Check the letter value, placement, nearby sequence, physical structure, catchwords, and catalog description. When the evidence is uncertain, record the uncertainty clearly.
