Ibn Arfa' Ra's

Ibn Arfa' Ra's is a chemistry 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 Ibn Arfa' Ra's rather than just read about it. In short: Ibn Arfa' Ra's (Arabic: ابن أرفع رأس – full name: Abū al-Ḥasan ʿAlī ibn Mūsa al-Anṣārī al-Andalusī ibn Arfaʿ Raʾs), flourished second half of the twelfth century, was a Maghrebi poet and alchemist. He is the author of an Arabic collection (dīwān) of alchemical poems called the Shudhūr al-dhahab ('Shards of Gold').

Key takeaways

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

Reference excerpt

Ibn Arfa' Ra's (Arabic: ابن أرفع رأس – full name: Abū al-Ḥasan ʿAlī ibn Mūsa al-Anṣārī al-Andalusī ibn Arfaʿ Raʾs), flourished second half of the twelfth century, was a Maghrebi poet and alchemist. He is the author of an Arabic collection (dīwān) of alchemical poems called the Shudhūr al-dhahab ('Shards of Gold'). Traditionally he was identified with a certain Ibn al-Naqirāt, a religious scholar living in Fez (Morocco) who died c. 1197. However, this identification is probably spurious. If so, virtually nothing is known about Ibn Arfa' Ra's's life. Probably born in Al-Andalus, perhaps in Granada, it is likely that he spent most of his life in Almohad Morocco. At some point he likely traveled to the Islamic East, where he may also have settled. Ibn Arfa' Ra's wrote a commentary on his own work Shudhūr al-dhahab under the name Ḥall mushkilāt al-Shudhūr ('Solution to the Problems of the Shudhūr'). He also wrote some alchemical poems in the muwashshaḥ genre (strophic verse) and a number of short prose works on alchemy. Two works on magic have also been attributed to him, but these are probably spurious.

Identity

Most traditional authors of Arabic biographical dictionaries identify Ibn Arfa' Ra's with a religious scholar called Ibn al-Naqirāt, whose fuller name was Abū al-Ḥasan ʿAlī ibn Mūsa ibn ʿAlī ibn Mūsa ibn Muḥammad ibn Khalaf al-Anṣārī al-Sālimī al-Jayyānī. The fullest version of Ibn Arfa' Ra's's name, as may be reconstructed from the earliest manuscripts, is Burhān al-Dīn Abū al-Ḥasan ʿAlī ibn Mūsa ibn Abī al-Qāsim al-Anṣārī al-Andalusī. Since both names share the major part Abū al-Ḥasan ʿAlī ibn Mūsa al-Anṣārī, they are close enough to raise the possibility that the two figures were indeed identical. However, neither Ibn al-Naqirāt's longer nasab (the part of his name indicating lineage) "son of Ali son of Musa son of Muhammad son of Khalaf", nor his nisbas (names referring to a place of origin) al-Sālimī (Medinaceli) or al-Jayyānī (Jaén) ever occur in the alchemical manuscripts. The biographical dictionaries in their entries on Ibn al-Naqirāt never actually mention the nickname (laqab) Ibn Arfaʿ Raʾs, nor the honorific Burhān al-Dīn, both of which often feature prominently in the alchemical manuscripts.

If Ibn Arfa' Ra's is identical with Ibn al-Naqirāt, some basic facts of his life are known. Ibn al-Abbar (died 1260) in his biographical dictionary Kitāb al-Takmila li-Kitāb al-Ṣila mentions that Ibn al-Naqirāt was born in 1121 or 1122 CE (515 AH) and that he died after 1196 or 1197 CE (593 AH), and that he was born in Al-Andalus but later moved to Fez (Morocco) where he became a khaṭīb (Islamic preacher). According to the broader biographical tradition, Ibn al-Naqirāt was an expert in qirāʾāt (variant readings of the Quran) as well as in the jurisprudence and hadith of the Maliki school, preaching in the renowned Qarawiyyin mosque. However, the divergence between the names in the biographical dictionaries and those given in the manuscripts of the alchemical works attributed to Ibn Arfa' Ra's, as well as certain details in reports relating to the two figures given by Ibn Khaldun (1332–1406) and Leo Africanus (c. 1494 – c. 1554), suggest that Ibn al-Abbar may have conflated the alchemist Ibn Arfa' Ra's with the religious scholar Ibn al-Naqirāt. In this case, very little remains that can be said about the life of Ibn Arfa' Ra's. Like Ibn al-Naqirāt, he originated in Al-Andalus, perhaps in Granada, and later settled elsewhere. Although the fact that he was sometimes called al-Maghribī indicates that he may also have settled in Morocco, the alchemical manuscripts make no mention of Fez or any other specific place. Alternatively, the nisba al-Maghribī may indicate that he left the Maghreb (the Islamic West, the region west of Egypt) and settled in the Mashreq (the Islamic East). In any case, it is clear that he spent a major part of his life in the West, most likely in Morocco. If the identification of Ibn Arfa' Ra's with Ibn al-Naqirāt is given up, the period in which he lived becomes very uncertain. Since Ibn al-Abbar knew of his works in the middle of the thirteenth century and some of the earliest commentaries on his work date from that period, Ibn Arfa' Ra's must have lived before c. 1250, but a terminus post quem is much harder to establish. The fact that Ibn Arfa' Ra's cites al-Mas'udi (died 957) may provide the earliest date for which there is hard evidence, although the lack of any mention of him by the alchemist poet al-Tughra'i (died 1121) makes it most likely that Ibn Arfa' Ra's lived in the twelfth century.

Works

Shudhūr al-dhahab Ibn Arfa' Ra's's most enduring work is a dīwān of alchemical poems called the Shudhūr al-dhahab ('Shards of Gold'). These poems, which all together comprise about 1400 lines, are arranged by the letter they use to rhyme, thus covering the entire Arabic alphabet. A large number of commentaries on the work were written by other Islamo-Arabic alchemists, among them commentaries by al-Irbilī (died 1257) and al-Sīmāwī (fl. 1250), as well as five commentaries by al-Jildakī (written c. 1337 – c. 1342) alone. The Shudhūr al-dhahab ranks among the first works to feature exegesis of the Quran (tafsīr) in an alchemical context.

Other works

Ibn Arfa' Ra's wrote a commentary on his own alchemical dīwān, called the Ḥall mushkilāt al-Shudhūr ('Solution to the Problems of the Shudhūr'). There are also some alchemical poems by Ibn Arfa' Ra's which are written in muwashshaḥ, a genre of Arabic poetry that uses strophic verse. These were not included in the Shudhūr al-dhahab because poems of the muwashshaḥ genre are usually excluded from dīwān collections. A number of short prose works have been attributed to Ibn Arfa' Ra's, but these have not yet been investigated:

Worked examples

Example 1 — a first encounter with Ibn Arfa' Ra's

Start with the simplest possible case. Write down what Ibn Arfa' Ra's claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Ibn Arfa' Ra's 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 Ibn Arfa' Ra's 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 Ibn Arfa' Ra's

In research
Ibn Arfa' Ra's appears in chemistry 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 Ibn Arfa' Ra's 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
Ibn Arfa' Ra's is common in secondary-school and first-year university syllabi. It links to neighbouring topics 12th-century Arabic-language writers, 12th-century deaths, Alchemists of the medieval Islamic world, so understanding it makes those chapters shorter.
In everyday life
Look for Ibn Arfa' Ra's 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.
