Muslim Rocket Technology

Arabic accounts report that Muslims introduced firearms into Islamic Spain, from where they passed to Italy, going from there to France, and finally Germany. Muslims also developed and refined gun powder and aquired rocket making technology. This article is a short account on the development of Muslim rocket technology, a constituent part of Islamic technology.

In the 13th century a Syrian scholar, Hassan Al-Rammah (d. 1294-1295), wrote a remarkable book on military technology, which became very famous in the west. The first documented rocket is included in the book, a model of which is exhibited at the National Air and Space Museum in Washington D.C. The author visited Washington in September 2000 where he obtained more information not only on the rocket but also on its fuel. Later, he acquired an edited copy of the book from the editor Ahmad Al-Hassan. This report depends on references (1-6).

The work discusses weapons and tactics. MS produced in Syria in the second half of the twelfth century. It is preserved at the Bodleian Library in Oxford, MS Huntington 264.

Gunpowder

The Chinese knew gunpowder in the 11th century but did not know the right proportions to get explosions and did not achieve the necessary purification of potassium nitrate. The first Chinese book, which details the explosive proportions, was written in 1412 by Huo Lung Ching [1].

Al-Rammah's book is the first to explain the purification procedure for potassium nitrate and described many recipes for making gunpowder with the correct proportions to acheive explosion. This is necessary for the development of canons. Partington [3] says "the collection of recipes was probably taken from various sources at different times in the author's family and handed down. Such recipes are described as tested." Al-Razi, Al-Hamdany and an Arabic-Syriaque manuscript of the 10th century describe potassium nitrate. Ibn Al-Baytar describes it in 1240. The Arabic-Syriaque manuscript of the 10th century gives some recipes of gunpowder. It is assumed that these were added in the 13th century.

The Latin book Liber Ignium of Marcus Graecus was originally written in Arabic and translated in Spain. It gives many recipes for making gunpowder, the last four of which may have been added to the book in 1280 or 1300 (6). "Did Roger Bacon derive his famous cryptic gunpowder formula in his Epistola of ca.1260 from the crusader Peter of Maricourt, some other traveller or from a wide range of reading from Arabic and alchemical books?" The references ([1]-[3]-[5]) doubt the correctness and the effectiveness of the recipe of Bacon.

The German scholar Albert Magnus obtained his information from Liber Ignium, which was originally an Arabic book as said before.

Evidence of the use of gunpowder during the crusades in Fustat, Egypt, in 1168 was found in the form of traces of potassium nitrate. Such traces were also found in 1218 during the siege of Dumyat and in the battle of Al-Mansoura in 1249 [1].

Winter [6] mentions that the Chinese may have discovered saltpeter (i.e. gunpowder), or else that discovery may have been transmitted to them by the Muslims whom they had plenty of opportunities of meeting either at home or abroad. Sarton refers to Arab-Muslim traders with China, as well as Muslim inhabitans in China. As early as 880 an estimated 120,000 Muslims, Jews and Persians lived in Canton alone.

By the 15th century, when this illustration was added to an earlier training maual, Maluk military texts included early forms of gun or hand-cannon as held by the man on the right. The picture also shows rpckets and incendiary weapons using various forms of gun-powder (Library of the Orintal Institure, St petersburg). source: David Nicolle and Sam Thompson, Medieval Siege Weapons (2): Byzantium, the Islamic World and India AD 476-1256 (Northants, UK: Osprey Publishing, 2003, p. 38).

Canons and Rockets

There are four Arabic Manuscripts (Almakhzoun-manuscripts), one in St Petersburg, two in Paris and one in Istanbul, dated from the 14th century describing the first portable canon with suitable gunpowder. This description is principally the same as for modern guns. Such canons were used in the famous battle of Ain-Galout against the Mongols (1260) [1]. The Mamlouks developed the canons further during the 14th century.

In Spain, the Arabs used canons defending Seville (1248), in Granada 1319, in (Baza or Albacete) 1324, in Huescar and Martos 1325, in Alicante (1331) and in Algeziras 1342-1344. Partington [3] says: "the history of artillery in Spain is related to that of the Arabs".

Partington [3] mentions that "Arabic accounts suggest that the Arabs introduced firearms into Spain, from where they passed to Italy, going from there to France, and finally Germany".

Also reported by Partington [3]: "Hassan Al-Rammah describes various kinds of incendiary arrows and lances and describes and illustrates what has been supposed to be a torpedo. This is called 'the egg which moves itself and burns'. The illustration and text suggest at least that it was intended to move on the surface of water. Two sheet iron pans were fastened together and made tight by felt; the flattened pear-shaped vessel was filled with "naphtha", metal filings, and good mixtures (probably containing saltpetre), and the apparatus was provided with two rods (as a rudder?) and propelled by a large rocket".

Ley [4] said: "Hassan Al-Rammah adds one unsuspected novelty: a rocket-propelled torpedo consisting of two flat pans, fastened together and filled with powder or an incendiary mixture, equipped with a kind of tail to insure movement in a straight line, and propelled by to large rockets. The whole was called the ‘self-moving and combusting moving and combusting egg', but no instances of its use are related".

According to Winter [6], "the Arabs, in any event, appear to have been the first to inherit (and possibly originate) the secret of the rocket, and it was through Arabic writings - rather than the Mongols- that Europe came to know the rocket. Two notable examples of Arabic knowledge of the rocket are the so-called "self-moving and combusting egg" of the Syrian Al-Hassan Al-Rammah (d. 1294-1295), details of which may be found in Ley's popular Rockets, Missiles and Space Travel and physician Yusuf ibn Ismail Al-Kutub's description (1311) of saltpeter ("they use it to make a fire which rises and moves, thus increasing it in lightness and inflammability")".
