# library/ibn-ezra — Works of Abraham Ibn Ezra (1089–1164)

This folder holds complete public-domain copies of works by **Abraham Ibn Ezra**
(אברהם אבן עזרא, 1089–1164), the Spanish-Jewish poet, biblical commentator, grammarian,
and scientist. The paper cites Ibn Ezra's scientific treatises — Sefer ha-Shem and Reshit
Hokhmah — alongside the arithmetic Sefer ha-Mispar already present here.

## Files present

### `sefer_ha_mispar_1895.txt` (pre-existing — not modified)
A public-domain Google-Books scan text of a German-language scholarly study/edition of
Ibn Ezra's *Sefer ha-Mispar* ("Book of the Number", arithmetic, c.1146), published 1895.
Pre-existing in this folder; left untouched per the batch instructions. (NB: this file is a
German academic study of Sefer ha-Mispar with Hebrew terms, not a clean Hebrew-only
transcript of the treatise.)

### `sefer_hashem_1834_furth.pdf` — Sefer ha-Shem (HOSTED, complete)

- **Work:** *Sefer ha-Shem* (ספר השם, "Book of the [Divine] Name"), composed **1148 CE**.
  Ibn Ezra's treatise on the Tetragrammaton and the divine name, with the gematria /
  letter-analysis relevant to this project.
- **Source:** HebrewBooks.org — sefer ID **35240**
  - Detail page: https://www.hebrewbooks.org/35240
  - Download: https://download.hebrewbooks.org/downloadhandler.ashx?req=35240
- **Edition:** פיורדא (Fürth), תקצ"ד — **Fürth 1834** (Hebrew year תקצד = 5594 AM =
  1834 CE). Author catalogued as "אבן עזרא, אברהם בן מאיר, 1089-1164".
- **Language:** Hebrew.
- **License:** Public Domain (1834 print; out of copyright worldwide).
- **Format:** PDF scan of the complete 83-page Hebrew edition (3.86 MB). No clean text
  derivative is available — HebrewBooks provides only the scanned PDF, and the PDF's
  embedded text layer is a non-reversible Hebrew OCR (RTL scrambling), so it cannot be
  reliably converted to a readable .txt and is therefore shipped as the verifiable PDF
  scan rather than as garbled text.
- **Completeness evidence:** 83 pages, full scan (title page through final page).
  Confirmed by HebrewBooks as the complete Sefer ha-Shem (Fürth 1834). The PDF text
  layer contains "םשה רפס" (ספר השם reversed) on the title page and "םשה" (השם) ~91
  times across the body.

## NOT HOSTED — Reshit Hokhmah (1147)

- **Work sought:** *Reshit Hokhmah* (ראשית חכמה, "Beginning of Wisdom"), Ibn Ezra's
  introduction to astronomy/astrology, composed **1147 CE** — his first scientific work.
- **Status:** **NOT FINDABLE as a free, complete, public-domain standalone text.**
- **Searches performed:**
  - **HebrewBooks.org** — a database search for "ראשית חכמה" returns only the *Reshit
    Hokhmah* of **Elijah de Vidas** (1579, the kabbalistic work — a DIFFERENT author and
    work) and of **Shem Tov ben Yosef Palquera**; none attributed to Abraham Ibn Ezra.
    A combined "ראשית חכמה" + author "אבן עזרא" search returns only de-Vidas/Palquera
    hits (matched on "חכמה"), not Ibn Ezra. Ibn Ezra's 62 author results on
    HebrewBooks contain no standalone Reshit Hokhmah. The 1922 collection *Kovetz
    Chochmat haRab"a* (ID 37048) is a compilation of Ibn Ezra's **introductions and
    poems**, not the scientific Reshit Hokhmah.
  - **archive.org** — 0 results for Ibn Ezra + "Reshit Hokhmah" / "Beginning of Wisdom"
    / "ראשית חכמה" (only the de Vidas 1579 *Sefer Reshit hokhmah*, a different work,
    appears under `seferreshithokhm00vida`).
  - **Sefaria** — no "Reshit Hokhmah" in the index.
- **Known edition:** the standard text is R. Levy, *The Beginning of Wisdom* (1939),
  which is **copyrighted** and is therefore not used, per the project IRON RULE.
- **Conclusion:** only a copyrighted modern critical edition (Levy 1939) is available;
  no public-domain Latin/Hebrew text or pre-1928 scan was found. Reported as
  NOT-HOSTABLE / MISSING rather than shipping a partial or copyrighted text.
