Botany
The
Muslim scientists made considerable progress
in biology especially in botany, and developed
horticulture to a high degree of perfection.
They paid greater attention to botany in comparison
to zoology. Botany reached its zenith in Spain.
Al-Masudi,
has given the rudiments of the theory of evolution
in his well known work Meadows of gold. Another
of his works Kitab al-Tanbih wal Ishraq advances
his views on evolution namely from mineral
to plant, from plant to animal and from animal
to man.
In
botany Spanish Muslims made the greatest contribution,
and some of them are known as the greatest
botanists of mediaeval times. They were keen
observers and discovered sexual difference
between such plants as palms and hemps. They
roamed about on sea shores, on mountains and
in distant lands in quest of rare botanical
herbs. They classified plants into those that
grow from seeds, those that grow from cuttings
and those that grow of their own accord, i.e.,
wild growth. The Spanish Muslims advanced in
botany far beyond the state in which "it
had been left by Dioscorides and augmented
the herbology of the Greeks by the addition
of 2,000 plants." Regular botanical gardens
existed in Cordova, Baghdad, Cairo and Fez
for teaching and experimental purposes. Some
of these were the finest in the world.
The
Cordovan physician, Al-Ghafiqi (D. 1165) was
a renowned botanist, who collected plants in
Spain and Africa, and described them most accurately.
According to G. Sarton he was "the greatest
expert of his time on simples. His description
of plants was the most precise ever made in
Islam; he gave the names of each in Arabic,
Latin and Berber". His outstanding work
Al Adwiyah al Mufradah dealing with simples
was later appropriated by Ibn Baytar."
Abu
Zakariya Yahya Ibn Muhammad Ibn Al-Awwan, who
flourished at the end of 12 century in Seville
(Spain) was the author of the most important
Islamic treatise on agriculture during the
mediaeval times entitled Kitab al Filahah.
The book treats more than 585 plants and deals
with the cultivation of more than 50 fruit
trees. It also discusses numerous diseases
of plants and suggests their remedies. The
book presents new observations on properties
of soil and different types of manures.
Abdullah
Ibn Ahmad Ibn al-Baytar, was the greatest botanist
and pharmacist of Spain--in fact the greatest
of mediaeval times. He roamed about in search
of plants and collected herbs on the Mediterranean
littoral, from Spain to Syria, described more
than 1,400 medical drugs and compared them
with the records of more than 150 ancient and
Arabian authors. The collection of simple drugs
composed by him is the most outstanding botanical
work in Arabic.
"This
book, in fact is the most important for the
whole period extending from Dioscorides down
to the 16th century." It is an encyclopedic
work on the subject. He later entered into
the service of the Ayyubid king, al-Malik al-l(amil,
as his chief herbalist in Cairo. From there
he traveled through Syria and Asia Minor, and
died in Damascus.
One
of his works AI-Mughani-fi al Adwiyah al Mufradah
deals with medicine. The other Al Jami Ji al
Adwiyah al Mufradah is a very valuable book
containing simple remedies regarding animal,
vegetable and mineral matters which has been
described above. It deals also with 200 novel
plants which were not known up to that time.
Abdul Abbas Al-Nabati also wandered along the
African Coast from Spain to Arabia in search
of herbs and plants. He discovered some rare
plants on the shore of Red Sea.
Another
botanist Ibn Sauri, was accompanied by an artist
during his travels in Syria, who made sketches
of the plants which they found.
Ibn
Wahshiya, wrote his celebrated work al-Filahah
al-Nabatiyah containing valuable information
about :animals and plants.
Many
Cosmographical encyclopedias have been written
by Arabs and Persians, which contain sections
on animals, plants and stones, of which the
best known is that of Zakariya al-Kaiwini,
who died in 1283 A. D. Al-Dinawari wrote an
excellent 'book of plants' and al-Bakri has
written a book describing in detail the 'Plants
of Andalusia'
Ibn
Maskwaih, a contemporary of Al-Beruni, advanced
a definite theory about evolution. According
to him plant life at its lowest stage of evolution
does not need any seed for its birth and growth.
Nor does it perpetuate its species by means
of the seed.
The
great advancement of botanical science in Spain
led to the development of agriculture and horticulture
on a grand scale. "Horticulture improvements" says
G. Sarton, "constituted the finest legacies
of Islam, and the gardens of Spain proclaim
to this clay one of the noblest virtues of
her Muslim conquerors. The development of agriculture
was one of the glories of Muslim Spain."
