The Cup Clock:
El-Cezeri describes the functioning of
the cup clock, an invention of himself,
as below: “The clock consists of a bowl
on a platform and closed from the top
by means of a flat lid. A carved gallery is
moving on the circumference of the ring
and there is a delicate horizontal ring on
the gallery. This ring is divided into2171/2
notches (=141/2 x 15). Each 15 notches
correspond to an equal hour (an hour
congruent to a day divided by 24).“
medicine and mathematical
sciences were
taught along with 4 main
schools of islamic jurisprudence
(fiqh). The university
building, which had also
been the venue for the official
routs held by the Caliph
for diplomatic guests, is being
utilized today as the Museum of
Islamic Culture and Art following its
restoration between 1945 and 1962.
Owns The Largest Collection
In the Islam Science and Technology Museum, the inventions
and other novelties brought about by the muslim scientists
and conferred to the usage of science, are exhibited
in 14 different pavillions, namely; Astronomy, Geography,
Maritime, Clocks, Geometry, Optics, Medicine, Chemistry,
Architechture, Physics and Technology, Battle Technics, Minerals
and Fossil Formations, Ancient Objects, and European
Glassware and Seramics in oriental form.
As the content of the museum manifests, muslim scientists
have set forth ground-breaking studies in every field
of science during the Golden Age. The works exhibited in
the museum, the instruments, devices are all reconstructed
in full conformity
with the original
information from
written documents
and existing pictures.
In the current conditions
the museum contains
the largest collection
in the world in terms
of islamic science and technology.We
were merely in a feeling
as if we were in a time machine
voyaging into the history, while every single
object we behold and every new bit of knowledge aroused
great admiration.
We understand that every functional device belonging to
islamic science, bore an esthetic value besides its functionality.
Astrolabes that measure the location of the earth by an
almost error-free accuracy through trigonometric method,
is a good example for this. And while talking about astrolabes,
it’s also possible to see in the museum the spherical
astrolabe, the inventor of which is known as Cabir bin Sinan
el-Harrani and the astrolabe in the shape of a rowboat built
on the principle of the world rotating around its own axis
invented by Ebu Said Ahmed bin Muhammed es-Siczi who
himself believed that the world rotated around its own axis.
