Hassan and his successors, for nearly three centuries, were not satisfied with having established their power in Persia: they soon found means to possess themselves of several strong places in Syria. Masyat, a place situated in the mountains of the Anti-Libanus, became their chief seat, in that province; and also the residence of the Prince of Alamut’s lieutenant. This branch of the Ismailites, which had settled in Syria, is the one mentioned by the western historians of the Crusades, and to which they have given the name of Assassin.

Before proceeding to the etymology of this name, we ought to observe, that Hassan, and the two princes who succeeded him in the sovereignty over the Ismailites of Persia and Syria, although attached to the peculiar tenets of the sect, nevertheless observed all the laws of Islamism; but, under the fourth prince of this dynasty, a great change took place in the religion of the Ismailites. This prince, who was named Hassan, son of Mohammed, pretended that he had received secret orders from the imam, by virtue of which he abolished all the external practices of Musulman worship; permitted his subjects to drink wine, and gave them a dispensation from all the obligations which the law of Mohammed imposes on its followers. He publicly announced, that the knowledge of the allegorical sense of the precepts, dispenses with the observation of the literal sense; and thus gained the Ismailites the name of Mulahid, or the Impious; a title by which they are most frequently designated by oriental writers. The example of this prince was followed by his son; and, for about fifty years, the Persian and Syrian Ismailites persisted in this doctrine. After this period, the worship was restored and preserved among them, until the entire destruction of their power.

The embassy which the Old Man of the Mountain, of the historians of the Crusades, that is, the sovereign of the Ismailites, sent to Amaury I. King of Jerusalem, falls under the reign of one of the two apostate princes, whom we have just mentioned. It is true, then, as William, Archbishop of Tyre, says, that the prince by whom this embassy was sent, had suppressed all the practices of the Musulman religion, destroyed the mosques, authorized incestuous unions, and allowed the use of wine and pork. When we read the sacred book of the Druses, or the fragments which we possess of those of the Ismailites, we have little hesitation in believing, that this prince, as the same historian asserts, was acquainted with the books of the Christians, and that he had formed a wish not to embrace the Christian religion, but to study more accurately its doctrines and observances.

Let us now pass to the name Assassin. This word, as I have already said, has been written in a variety of ways; but to confine myself to those possessing the best authority, I shall state, that it has been pronounced Assassini, Assissini, and Heississini. Joinville has written Haussaci. The limits which I have prescribed myself, forbid my entering here into the discussion of the various etymologies of this name, which have been proposed by different learned persons. Suffice it for me to say, that they have all been mistaken, because they had, no doubt, never met with the word in any Arabic author. The Assassins are almost always called by oriental historians, Ismailites, Mulahid (i. e. the Impious), or Batenites, signifying partisans of the allegorical sense. Only one literary person, in a letter, preserved by Menage, had a glimpse of the true etymology; but he had erected it on bad foundations, as he had not the slightest suspicion of the motive which led to the Ismailites being designated by this term.

One of the most illustrious, most certainly, of the victims to the fury of the Ismailites, is Saladin. It is true, this great prince escaped their attacks; but he was twice on the point of losing his life by these wretches’ daggers, for which he afterwards reaped a striking revenge. It is in perusing the account of these reiterated attempts, in some Arabic authors, contemporaries of Saladin, and ocular witnesses of what they relate, that I have been convinced that the Ismailites, or, at least, the men whom they employed to execute their horrible projects, were called, in Arabic, Hashishin in the plural, and Hashishi in the singular; and this name, slightly altered by the Latin writers, has been expressed as exactly as possible by several Greek historians, and by the Jew, Benjamin, of Tudela.

As for the origin of the name in question, although I have not gleaned it from any one of the oriental historians that I have consulted, I have no doubt whatever that denomination was given to the Ismailites, on account of their using an intoxicating liquid, or preparation, still known in the east by the name of Hashish. Hemp leaves, and some other parts of the same vegetable,[302] form the basis of this preparation; which is employed in different ways, either in liquid, or in the form of pastiles, mixed with saccharine substances; or even in fumigation. The intoxication produced by the hashish, causes an ecstasy similar to that which the orientals produce by the use of opium; and, from the testimony of a great number of travellers, we may affirm, that those who fall into this state of delirium, imagine they enjoy the ordinary objects of their desires, and taste felicity at a cheap rate; but the too frequent enjoyment changes the animal economy, and produces, first, marasmus, and then, death. Some, even in this state of temporary insanity, losing all knowledge of their debility, commit the most brutal actions, so as to disturb the public peace. It has not been forgotten, that when the French army was in Egypt, the general-in-chief, Napoleon, was obliged to prohibit, under the severest penalties, the sale and use of these pernicious substances; the habit of which has made an imperious want in the inhabitants of Egypt, particularly the lower orders. Those who indulge in this custom, are, to this day, called Hashishin; and these two different expressions explain why the Ismailites were called by the historians of the Crusades, sometimes Assissini, and sometimes Assassini.

Let us hasten to meet an objection, which cannot fail to be made against the motive on which we found the origin of the denomination of Assassins, as applied to the Ismailites. If the use of intoxicating substances, prepared from hemp leaves, is able to disturb the reason; if it throws a man into a sort of delirium, and makes him take dreams to be realities; how could it be proper for people who had need of all their sang-froid and mental calmness, in order to execute the murders with which they were charged, and who were seen to proceed to countries most remote from their own residence, to watch many days for an opportunity favourable to the execution of their designs; to mix among the soldiers of the prince whom they were about to immolate to the will of their chieftain; to fight under his colours, and skilfully to seize the instant which fortune offered for their purpose? This, certainly, is not the conduct of delirious beings, nor of madmen, carried away by a fury which they are no longer able to control; such as travellers describe those who ran a muck, so much dreaded among the Malays and Indians. One word will suffice, in answer to this objection; and with this, Marco Polo’s account will supply us. This traveller, whose veracity is now generally acknowledged, informs us, that the Old Man of the Mountain educated young men, selected from the most robust inhabitants of the places under his sway, in order to make them the executioners of his barbarous decrees. The whole object of their education went to convince them, that, by blindly obeying the orders of their chief, they insured to themselves, after death, the enjoyment of every pleasure that can flatter the senses. For this purpose, the prince had delightful gardens laid out near his palace; there, in pavilions, decorated with every thing rich and brilliant that Asiatic luxury can devise, dwelt young beauties, dedicated solely to the pleasures of those for whom these enchanting regions were destined. Thither, from time to time, the princes of the Ismailites caused the young people, whom they wished to make the blind instruments of their will, to be transported. After administering to them a beverage which threw them into a deep sleep, and deprived them, for some time, of the use of their faculties, they were carried into those pavilions, which were fully worthy of the gardens of Armida; on their awaking, every thing which met their eyes, or struck their ears, threw them into a rapture, which deprived reason of all control over their minds; and uncertain whether they were still on earth, or whether they had already entered upon the enjoyment of that felicity, the picture of which had so often been presented to their imagination, they yielded in transport to all the kinds of seduction, by which they were surrounded. After they had passed some days in these gardens, the same means which had been adopted to introduce them, without their being conscious of it, were again made use of to remove them. Advantage was carefully taken of the first moments of an awakening, which had broken the charm of so much enjoyment, to make them relate to their young companions, the wonders of which they had been the witnesses; and they remained themselves convinced, that the happiness which they had experienced in the few days which had so soon elapsed, was but the prelude, and, as it were, the foretaste of that of which they might secure the eternal possession, by their submission to the orders of their prince.

Although some exaggeration might be supposed to exist in the Venetian traveller’s recital; and although, instead of crediting the existence of these enchanted gardens, which is, however, attested by many other writers, we should still reduce all the wonders of that magnificent abode to a phantom, produced by the exalted imagination of the young men who were intoxicated with the hashish, and who, from their infancy, had been nursed with the idea of this happiness; it would not be the less true, that we here find the use of a liquor, destined to deaden the senses, and in which we cannot overlook, that its employment, or rather abuse, is spread throughout a great part of Asia and Africa. At the epoch of the Ismailitic power, these intoxicating preparations were not yet known in the Moslem countries. It was only at a later period, the knowledge of it was brought from the most eastern regions, probably even from India into the Persian provinces. Thence it was communicated to the Musulmans of Mesopotamia, Asia Minor, Syria, and Egypt. No doubt, the Ismailites, whose doctrines had several points of resemblance with those of the Indians, had acquired this knowledge earlier, and preserved it as a precious secret, and as one of the principal springs of their power. This conjecture is supported by the fact, that one of the most celebrated Arabian writers attributes the introduction amongst the Egyptians, of an electuary prepared from hemp, to a Persian Ismailite.

I shall conclude this memoir by observing, that it is not impossible that hemp, or some parts of that vegetable, mixed with other substances unknown to us, may have been sometimes employed to produce a state of phrenzy and violent madness. We know that opium, the effects of which are, in general, analogous to those of intoxicating preparations made with hemp, is, nevertheless, the means made use of by the Malays, to throw themselves into that state of fury, during which, being no longer masters of themselves, they murder every one they meet, and blindly precipitate themselves into the midst of swords and lances. The means employed thus to alter the effects of opium is, if travellers are to be believed, mixing it with citron juice, and to allow the two substances to incorporate for a few days.
