Pirkei De-Rabbi Eliezer

Pirkei De-Rabbi Eliezer is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pirkei De-Rabbi Eliezer rather than just read about it. In short: Pirkei de-Rabbi Eliezer (Jewish Babylonian Aramaic: פִּרְקֵי דְּרַבִּי אֱלִיעֶזֶר, romanized: pirqe də-rabbi ʾeliʿezer, 'Chapters of Rabbi Eliezer'; abbreviated פדר״א, 'PRE') is an aggadic-midrashic work of Torah exegesis and retellings of biblical stories. Traditionally, the work is attributed to the tanna Eliezer ben Hurcanus and his school.

Key takeaways

  • Pirkei De-Rabbi Eliezer belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Pirkei De-Rabbi Eliezer to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Pirkei De-Rabbi Eliezer from memory before moving on to harder problems.

Reference excerpt

Pirkei de-Rabbi Eliezer (Jewish Babylonian Aramaic: פִּרְקֵי דְּרַבִּי אֱלִיעֶזֶר, romanized: pirqe də-rabbi ʾeliʿezer, 'Chapters of Rabbi Eliezer'; abbreviated פדר״א, 'PRE') is an aggadic-midrashic work of Torah exegesis and retellings of biblical stories. Traditionally, the work is attributed to the tanna Eliezer ben Hurcanus and his school. Modern research suggests that the text is pseudepigraphic from the Geonic period of the eighth century, written in or near the Land of Israel.

First chapters and attribution to Eliezer Medieval scholarly texts also referred to Pirkei De-Rabbi Eliezer as Pirkei DeRabbi Eliezer HaGadol and as Baraita DeRabbi Eliezer. Whereas medieval scholars attributed the work to the Tanna Eliezer ben Hyrcanus, Abraham Zacuto wrote, "it is well known that although it is attributed to Rabbi Eliezer, it was written by later generations". Subsequently, research by Leopold Zunz claims that Pirkei DeRabbi Eliezer is an pseudepigraphic work. The first two chapters of the work are dedicated to the story of Eliezer ben Hyrcanus's approach to Torah, serving as an introduction to the work and providing background about the author. These chapters are derived from Avot de-Rabbi Natan, Version B, Chapter 13, and their originality in Pirkei DeRabbi Eliezer is a matter of scholarly debate. Many researchers speculate that these chapters are a later addition and not original to the Midrash.This hypothesis is based on evidence from the Cairo Geniza, where a list of books includes a manuscript in which the midrash begins at Chapter 3. Additionally, in one manuscript, the title of the midrash appears only in Chapter 3. According to this hypothesis, there is no internal evidence in the midrash itself to attribute it specifically to Eliezer, and the name Pirkei DeRabbi Eliezer was given because he is the first sage mentioned at the beginning of Chapter 3, "Rabbi Eliezer ben Hyrcanus opened...", as it was customary to name works after the first sage mentioned in them. Eliezer Treitl disagrees with this view and believes that the chapters should not be excluded from the canon for two reasons: These chapters appear in all the complete manuscripts of the work that exist; the language of the chapters slightly differs from their source in Avot DeRabbi Natan in a way that suits the unique language and stylistic nuances of Pirkei DeRabbi Eliezer.

Time and place of the composition The first scholar to establish the dating of the midrash was Leopold Zunz. Following his work, the widely accepted opinion in research is that the midrash was written around the eighth century. Zunz dates the book from the beginning to the middle of the eighth century. The evidence Zunz brings for this dating is that the author frequently refers in sermons to Ishmael and the kingdom of the children of Ishmael, and condemns their rule. Ishmael's name is interpreted at the beginning of Chapter 32 as: "And why is his name called Ishmael? Because in the future, the Holy One, blessed be He, will hear the cry of the people from what the children of Ishmael are destined to do in the land at the end of days." At the end of Chapter 30, the following apocalyptic vision appears,

Rabbi Ishmael says, Fifteen things the children of Ishmael are destined to do in the land at the end of days, and these are they: They will measure the land with ropes, make cemeteries for the resting place of sheep dung, measure in them and from them on the tops of mountains, increase lies, conceal the truth, distance law from Israel, increase sins in Israel, the worm will be as wool, the paper and pen will wither, the kingdom's rock will be rejected, they will rebuild ruined cities, clear roads, plant gardens and orchards, repair breaches in the walls of the Temple, build a structure in the sanctuary, and two brothers will stand over them as leaders in the end, and in their days the sprout of David (the Messiah) will stand. According to Zunz, the "structure in the sanctuary" refers to the Dome of the Rock, which was built on the Temple Mount at the end of the seventh century. The rejection of the "kingdom's rock" refers to the minting of Muslim coins, which also occurred at the end of that century. Furthermore, the text bears a distinct similarity to the Geonic literature, a remarkable resemblance to the Targum Pseudo-Jonathan, and messianic sayings that set the expected year of redemption as 729. Thus, the work was not written before the end of the seventh century. The opening passage of Chapter 3 appears in the letter of Pirqoi ben Baboi, who operated at the end of the eighth century or the beginning of the ninth century, indicating that the work was not written after the ninth century. Regarding where the midrash was composed, extensive references to the rule of Ishmael indicate that the work was most likely composed in the Muslim-ruled Bilad al-Sham or its surroundings. Furthermore, in chapter 8, the work emphasizes the exclusive right of the "sages of the Land of Israel" to establish the calendar, stating that even shepherds and laypeople there are preferable to the righteous and prophets in the Diaspora, only the inhabitants of the Land of Israel have the right to establish the calendar. In addition, the text cites various customs of the Land of Israel. For example, the custom of defloration with a finger (mentioned in Chapter 16) is explicitly noted in the Book of Differences, as discussed by Mordecai Margalioth in 'Differences between Easterners and Residents of the Land of Israel'.

Worked examples

Example 1 — a first encounter with Pirkei De-Rabbi Eliezer

Start with the simplest possible case. Write down what Pirkei De-Rabbi Eliezer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pirkei De-Rabbi Eliezer before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pirkei De-Rabbi Eliezer ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pirkei De-Rabbi Eliezer

In research
Pirkei De-Rabbi Eliezer appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Pirkei De-Rabbi Eliezer in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Pirkei De-Rabbi Eliezer is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aggadic Midrashim, Hebrew-language literature, Jewish cosmology, so understanding it makes those chapters shorter.
In everyday life
Look for Pirkei De-Rabbi Eliezer outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
