Time Reckoning

Era means a definite space of time, reckoned from the beginning of some past year, in which either a prophet, with signs and wonders, and with a proof of his divine mission, was sent, or a great and powerful king rose, or in which a nation perished by a universal destructive deluge, or by a violent earthquake and the sinking of the earth, or a sweeping pestilence, or by intense drought, or in which a change of dynasty or religion took place, or any grand event of the celestial and the famous tellurian miraculous occurrences, which do not happen save at long intervals and at times far distant from each other. Al-Bîrûnî (1879:16)

Time is relative. Given the modern world’s reliance on formalized calendars and machines that define time for us, it is easy to forget that the expansion of Islam occurred at a time when telling time was not dependent on a formal science of astronomy. How time is measured is not only a practical issue but also reflective of the desired interval of duration and the precision in defining it. Simple observation of the sun rising and setting, as well as its location, can easily yield calendars to determining hours, days, months and years. Similarly, the moon’s phases made it a useful measure for the Islamic lunar calendar. Observations of movements by the stars, as well as the planets, also provided practical ways of measuring units of time both short and long. Continue reading Islamic Folk Astronomy #2 →

Islamic Folk Astronomy #1

Folklore and Proverbs, Islamic Sciences


from Ibn Balkhi’s manuscript on astronomy, 850 CE

It was He that gave the sun his brightness and the moon her light, ordaining her phases that you may learn to compute the seasons and the years. He created them only to manifest the truth. He makes plain His revelation to men of understanding. Yûnus 10:9 (Dawood 1968:64)

When the Quran was revealed in seventh century Arabia as the basis for Islam, references were made to the sun, moon and stars as evidence of the creative power and practical foresight of God. The idea that God, or a particular god or goddess, had created the visible heavens was not unique. Creating stories about astronomical phenomena is as old as the first civilizations that appeared in the ancient Near East. Some of these survived, in highly edited variants, in the scriptures of Judaism and Christianity. As Muslim science evolved, a variety of religious and scientific knowledge from classical Greek texts, as well as Zoroastrian and Hindu sources, was encountered. While the influence of these classical and textual traditions on Islamic astronomy has been the focus of much previous study on the history of Islamic science, little attention has been paid to the oral folk traditions of peoples who embraced Islam. How ordinary Muslims viewed the same heavens visible to educated scientist or illiterate shepherd is the subject of this chapter. For practical reasons the focus here will be on the Middle East, especially the textual information on the pre-Islamic Arabs of the Arabian Peninsula and contemporary tribal groups in the region.

What is Islamic Folk Astronomy?

It is unfortunate that many times the idea of “folk astronomy” is understood mainly by what it is not. Continue reading Islamic Folk Astronomy #1 →

Toronto Talks

Anthropology/Sociology, Conferences and Talks, Folklore and Proverbs, Islamic Sciences, Islamic Texts, Orientalism

If you are reading this post today, Wednesday, I may very well be in the air on my way to Toronto, where I will be giving two lectures. Anyone who is interested is invited to attend.

Thursday, January 14th, 2010

Interdisciplinary Perspectives on Science presents:

Daniel Martin Varisco (Hofstra University)

Star Gazing through Religious Phrasing: The Origins of a Lunar Zodiac in Early Islamic Astronomy

At Ryerson University in ENG LG14, George Vari Engineering and Computing Centre, 245 Church St. from 6:00pm to 8:00pm.

One of the most important astronomical time-keeping calendars from the Arabian Peninsula is the so-called anwâ’, which early Muslim astronomers equated with the tradition of 28 lunar stations (manâzil al-qamar). Through a study of this calendar in pre-Islamic Arabic poetry and Arabic lexical texts and by comparison to ethnographic accounts of existing Arabian star calendars, I argue that the system described in the evolving Islamic science of astronomy is one that did not arise in the Arabian Peninsula but was the result of cleansing the magical elements out of the earlier star lore and modeling this on the lunar zodiac of Sassanid Iran and India.


Refreshments will be served after the discussion.

The second talk will take place at the University of Toronto on Friday, January 15:

Anthropology Colloquium Series

Saliba on Europe and Islamic Science

Books You Should Read, Islam in Europe, Islamic Sciences, Scholars

[On Rorotoko, historian of science George Saliba discusses the writing of his recent book, Islamic Science and the Making of the European Renaissance (Cambridge: MIT Press, 2007).]

This book started almost ten years ago. Initially, I wanted to know what were the conditions under which a civilization could produce science afresh.

I was trained in ancient Semitics, and mathematics, but I was always interested in these rumors that the general reader knows about, that the great invention of science was a really Greek project. And that everything else is either a shadow or a continuation of the classic antiquity.

Growing up, you assimilate these paradigms. You begin to think that these are the normal things. But then, trained in mathematics, and beginning to read a little bit of what was produced in the Islamic civilization, in science, I grew curious. I grew curious because I began to note that some of the science produced was not a shadow of the Greek project. It was more re-focusing of light, a new way of looking at things, which the Greeks did not know.

I began to also wonder about a fact that many a student of history and general reader would know. That there was this period of fantastical effervescence in the classical Greek tradition, say from the 4th century BC to the 2nd century AD. All the major names that we can think of happen to be in this period, all the major classics, in every discipline you can think of, from Plato to Aristotle to Ptolemy to Euclid to Diophantus to Galen to Dioscorides. And all comes to an end by the 2nd century. Then nothing happened. And then, all of a sudden, we begin to hear, in the 9th century, of the crazy caliphs of Baghdad who are spurring this and that, translating this and that, incorporating all of the Greek material.

Arabic Talismania

Islamic Sciences, Miniatures

I have had always had a fascination with the variety of astrological, magical and prognosticative manuscripts available in Arabic. Living in the post-Enlightenment modernity era, we scholars tend to think of astrology as a quaint feature of past pre-scientific thinking and now abandoned the New Age enthusiasts. There are, however, thousands of Arabic manuscripts that are magical, in more than the usual sense. These offer a window, however mysterious, into the concerns and fears of the past. I recently came across an extraordinary website, Digital Occult Manuscripts, which has uploaded images of numerous Arabic occult texts. I cannot find information on who puts out the project, but it is an amazing source of documents (although usually just a few pages of each manuscript) and a joy just to browse through. Here is one of the images, a talismanic man from a 12th century text by al-Ghazali.

MEMO FROM ALEXANDRIA
Harnessing Darwin to Push an Ancient Intellectual Center to Evolve

By MICHAEL SLACKMAN, The New York Times, November 26, 2009

ALEXANDRIA, Egypt — It is not that Charles Darwin and the theory of evolution are unknown here. But even among those who profess to know something about the subject, the common understanding is that Darwin said man came from monkeys.

Darwin, of course, did not say man came from monkeys. He said the two share a common ancestor. But to discuss Darwin anywhere is not just to explore the origin of man. It is inevitably to engage in a debate between religion and science. That is why, 150 years after Darwin published “On the Origin of Species,” the British Council, the cultural arm of the British government, decided to hold an international conference on Darwin in this conservative, Sunni Muslim nation.

It was a first.

“A lot of people say his theories are wrong, or go against religion,” said Martin Davidson, chief executive of the British Council. “His ideas provoke, but if we are going to understand each other, we have to discuss things that divide us.” Continue reading Darwin, Egyptian Style →

Saliba on Islamic Science and the Renaissance

Books You Should Read, Islamic Sciences

Sex, flies and videotape: the secret lives of Harun Yahya

Ethics, Islamic Sciences, Journalism and Media, Turkey

by Halil Arda, The New Humanist, Volume 124, Issue 5, September/October 2009

Inspired by the high profile of its Christian American counterpart, Muslim creationism is becoming increasingly visible and confident. On scores of websites and in dozens of books with titles like The Evolution Deceit and The Dark Face of Darwinism, a new and well-funded version of evolution-denialism, carefully calibrated to exploit the current fashion for religiously inspired attacks on scientific orthodoxy and “militant” atheism, seems to have found its voice. In a recent interview with The Times Richard Dawkins himself recognises the impact of this new phenomenon: “There has been a sharp upturn in hostility to teaching evolution in the classroom and it’s mostly coming from Islamic students.”

The patron saint of this new movement, the ubiquitous “expert” cited and referenced by those eager to demonstrate the superiority of “Koranic science” over “the evolution lie”, is the larger-than-life figure of Harun Yahya. Continue reading Sex, flies and videotape: the secret lives of Harun Yahya →
