Extractions: ibn AL-BATTANI Abu Abdallah Mohammad ibn Jabir ibn Sinan al-Raqqi al-Harrani al-Sabi al-Battani. (sometimes known by a latinised version of his name Albatenius) was born in Harran, Mesopotamia (now Turkey). His family were members of the Sabian sect, a religious sect of star worshippers from Harran. Being worshipers of the stars meant that the Sabians had a strong motivation for the study of astronomy and they produced many outstanding astronomers and mathematicians such as Thabit ibn Qurra. In fact Thabit was also born in Harran and would have still have been living there at the time that al-Battani was born. Al-Battani, unlike Thabit, was not a believer in the Sabian religion and records indicate that he was a Muslim. He composed a work on astronomy, with tables, containing his own observations of the sun and moon and a more accurate description of their motions than that given in Ptolemy's "Almagest". Al-Battani's Kitab al-Zij is his most important work and it describes the division of the celestial sphere into the signs of the zodiac and into degrees. The necessary background mathematical tools are then introduced such as the arithmetical operations on sexagesimal fractions and the trigonometric functions. Al-Battani's other achievements included cataloguing 489 stars, refining the existing values for the length of the year (which he gave as 365 days 5 hours 48 minutes 24 seconds) and defining the seasons. He died in Qasr al-Jiss, Iraq in 929.
