Ali ibn Muhammad ibn Abbas (923–1023) also known as Abu Hayyan al-Tawhidi was born in 923 near Baghdad or Fars, and died in 1023 in Shiraz. Al-Tawḥidi was born into a poor family that sold dates, and spent much of his childhood as an orphan in the care of his uncle, who treated him poorly. He has left a set of literary, philosophical, and Sufi works. Al-Imta wa al-Mu’anasa, has a chapter on zoology perhaps based on Timotheus of Gaza's book on animals. His few remarks on East Africa are indeed about the national character of the Zanj.

Which is the wisest of all nations?
The Chinese we said; People of furnishings and handicrafts, he replied, with neither thought nor reflection. The Turks we said; Wild beasts for the frag he replied, The Indians we said;
People of fantasy he said of legerdemain and conjuring and tricks. The Zanj we said; Freckles cattle he replied....

.... In consequence, good and bad qualities are spread among the whole of mankind and implanted in all of them. The Persians have statecraft, civility, rules, and etiquette. The Byzantines
have science and wisdom; the Indians have thought and reflection and nimbleness and magic and perseverance. The Turks have courage and impetuosity, the Zanj have patients and toil and
merriment, the Arabs are intrepid, hospitable, loyal, gallant, generous, protective, eloquent, and cogent....

On Languages;
We have heard many languages (even if we do not understand them) of all nations, such as the languages of our friends the Persians, Indians, Turks, Khwarezinians (1), Slavs, Andalusians (2)
and Zanj, and we found nothing in these languages like the limpidity of Arabic

The elephant’s teeth (begin to) grow as soon as it is born. As to its big teeth, or tusks, they come out, when it has become a youngster or full grown.

All beasts of prey (siba) and (other) quadrupeds (dawabb) when walking advance the right fore-leg (together) with the left hint-leg. The giraffe (zarafa) is to be found only in an area where water is scarce (3). If horse-breeders wish to have an ass cover a mare………..

The rhinoceros (himar wahshi) is a cross between a mare and an elephant. It has a horn growing from its nose [that looks] like a [drawn] sword. When striking at a tree it fells it with it. It fights with the elephant and slits its belly open with its horn. No female of this species has ever been sighted. In the sea there is a fish called bus …..
Vol1 p65-66
The male elephant (fil) lacks [spontaneous] desire for copulation. When desiring a young one he goes together with the female to meadows and garden-areas. Where mandrake (luffah) is to be found. This plant, by its odour and warming- power, arouses his lust and they copulate. The female, when bringing forth, does so while standing, for her joints do not bend as do the joints of those [animals] which drop kneeling or crouching. Yet she gives birth in water out of fear for her young one, lest it die when falling to the ground. So she goes to the shore of the sea, until the water reaches up to her belly, and drops her young one on the water as [onto] a soft mat. The male, in the meantime, guards her and her young one from the serpent.
How violent is the elephant's enmity for the serpent ! Whenever an elephant encounters a serpent he does tread on it and kill it. When falling on its side the elephant is unable to get up. It sleeps only leaning against a tree. This is the reason why the people of those regions (i.e. where the elephant is found), since they know how the elephant sleeps, go to a tree and saw into it; and if an elephant, comes to the tree and leans against it, both fall to the ground together. At that moment the elephant cries violently in a loud voice; at which many [other] elephants gather round it endeavouring to help it rise and get restored to normal. Yet they are unable to achieve this, and, therefore, the whole herd cries out in one voice out of impatience at the failure and inability. Then an elephant approaches which is smaller-bodied though craftier than they, places its trunk beneath the fallen elephant and all [the others] do likewise, putting their trunks beneath it, until, with their support, it gets onto its feet again.
The elephant’s head is set on a short neck, but instead of a long neck it was furnished with a long trunk to compensate for the handicap. With it does it take its food and drink. Its legs are created unjointed; rather are they like massive pillars and solid columns, that they (may be able to) carry the bulk and heavy (of its body). They are connected to small hocks which (however), do not bend or move on joints; for its bones are all of one piece. Its span of life stretches up to three hundred years; yet ticks and gnats (baqq) befall elephants and do them harm, (wherefore they often die earlier)

Then I recounted: The learned in the nature of the animals maintain that elephants are generated only on the islands of the southern seas and under the orbit of Aries. The giraffe (zarafa) is found only in the country of the Habash. The sable (sammur)….

Another bedouin said: Their dispute about grammar makes me feel a stranger until [or: to the point that] I heard the speech of the Zanj and the Byzantines.
This line of poetry is attributed to a certain Mu'ád b. Muslim al-Harra' Abu Muslim(d. 187/802 or 190/805), teacher of the Umayyad caliph 'Abd al-Malik b. Marwan.

Then he looked at another Zanjiyya who wore a silver knuckle ring on her feet, and said: Her leg is like the silver-plated penis of a donkey.

(citing ibn ar Rumi)
White and black hair on my head: two peoples, Byzantines and Zanj, have settled on my head. The young raven flew away from my head, and instead the king bird has taken up residence on it. So two colors have spread on the courtyard of my head.

We have brought pressed dates that resemble the zanjs' noses. That is, they are flat.
Note: My reason for adding so much poetry is that it gives a less racist picture then the philosophers give.

(2) Andalusia: Muslim Spain.
(3) And the giraffe: in areas with little water: This is also repeated by many authors; Abu Hayyan al-Tawhidi (d1023); Ibn Sida (1066); Shah Mardan Ibn Abi al-Khayr (11th); Al Marvazi: (1120); Ibn Manzur: (1290).
