Although Islamic civilisation declined in the 13th century,
its impact outlived it. When Alfonso of Castile (1223-84) sought to
construct an armillary sphere, ‘the finest and best that had yet been
made', he turned to the Muslims.[16]
He had Al-Zarqali’s safiha was translated into Latin
. Subsequently, Regiomontanus published a collection of problems on the
‘noble instrument of the safiha.'[17]
Regiomontanus also studied Al-Farghani's Compendium of astronomy,
which was translated into Latin by both Gerard of Cremona and Johanes
Hispalensis.[18]
Melanchthon published an edition based on the work of Regiomontanus at
The greatest Islamic impact on Renaissance scholars was on Copernicus.
He relied heavily in his book De Revolutionibus not just on
al-Zarqali and al-Battani but most of all on Ibn al-Shatir and the
astronomers at the Maragha observatory for his planetary models and
theory.[20]
In
the 1950s, Kennedy discovered that the geocentric planetary models of
Ibn al-Shatir in Nihayat al-sul were mathematically identical
with the heliocentric models of Copernicus.[21]
Saliba made a very convincing demonstration of this borrowing by
Copernicus.[22]
North, equally, stresses that Copernicus made repeated uses of his
Muslim predecessors, and traces the line of transmission to
Just like Copernicus, the mathematician Laplace relied heavily on Ibn
Yunus's tables from his Al-Zij al-Hakim, using the tables in his
determination of the ‘Obliquity of the Ecliptic' and the ‘Inequalities
of Jupiter’s and Saturn's; whilst the American Newcomb used its
observations of eclipses in his investigations on the motions of the
moon.[24]

astronomical knowledge also travelled East; in the year 1266, Jamal
