SASSA, MYRRH, and OPOCALPASUM.
At the time when I was on the borders of the Tal-Tal, or Troglodyte country, I sought to procure myself branches and bark of the myrrh-tree, enough preserved to be able to describe it and make a design; but the length and ruggedness of the way, the heat of the weather, and the carelessness and want of resources of naked savages always disappointed me. In those goat-skin bags into which I had often ordered them to put small branches, I always found the leaves mostly in powder; some few that were entire seemed to resemble much the acacia vera, but were wider towards the extremity, and more pointed immediately at the end. In what order the leaves grew I never could determine. The bark was absolutely like that of the acacia vera; and among the leaves I often met with a small, straight, weak thorn, about two inches long.
These were all the circumstances I could combine relative to the myrrh-tree, too vague and uncertain to risk a drawing upon, when there still remained so many desiderata concerning it; and as the king was obstinate not to let me go thither after what had happened to the surgeon’s mate and boat’s crew of the Elgin Indiaman[29], I was obliged to abandon the drawing of the myrrh-tree to some more fortunate traveller, after having in vain attempted to procure it at Azab, as I have already mentioned.
At the same time that I was taking these pains about the myrrh, I had desired the savages to bring me all the gums they could find, with the branches and bark of the trees that produced them. They brought me at different times some very fine pieces of incense, and at another time a very small quantity of a bright colourless gum, sweeter on burning than incense, but no branches of either tree, though I found this latter afterwards in another part of Abyssinia. But at all times they procured me quantities of gum of an even and close grain, and of a dark brown colour, which was produced by a tree called Sassa, and twice I received branches of this tree in tolerable order, and of these I made a drawing.
Some weeks after, while walking at Emfras, a Mahometan village, whose inhabitants are myrrh merchants, I saw a large tree with the whole upper part of the trunk, and the large branches, so covered with bosses and knobs of gum, as to appear monstrously deformed, and inquiring farther about this tree, I found that it had been brought, many years before, from the myrrh country, by merchants, and planted there for the sake of its gum, with which these Mahometans stiffened the blue Surat cloths they got damaged from Mocha, to trade in with the Galla and Abyssinians. Neither the origin of the tree which they called Sassa, nor the gum, could allow me to doubt a moment that it was the same as what had been brought to me from the myrrh country, but I had the additional satisfaction to find the tree all covered over with beautiful crimson flowers of a very extraordinary and strange construction. I began then a drawing anew, with all that satisfaction known only to those who have been conversant in such discoveries.

I took pieces of the gum with me; it is very light. Galen complains that, in his time, the myrrh was often mixed with a drug which he calls Opocalpasum, by a Greek name, but what the drug was is totally unknown to us at this day, as nothing similar to the Greek name is found in the language of the country. But as the only view of the savage, in mixing another gum with his myrrh, must have been to increase the quantity, and as the great plenty in which this gum is produced, and its colour, make it very proper for this use, and above all, as there is no reason to think there is another gum-bearing tree of equal qualities in the country where the myrrh grows, it seems to me next to a proof, that this must have been the opocalpasum of Galen.
I must however confess, that Galen says the opocalpasum was so far from being an innocent drug, that it was a mortal poison, and had produced very fatal effects. But as those Troglodytes, though now more ignorant than formerly, are still well acquainted with the properties of their herbs and trees, it is not possible that the savage, desiring to increase his sales, would mix them with a poison that must needs diminish them. And we may therefore without scruple suppose that Galen was mistaken in the quality ascribed to this drug, and that he might have imagined, from tenderness to the profession, that people died of the opocalpasum who perhaps really died of the physician: First, Because we know of no gum or resin that is a mortal poison: Secondly, Because, from the construction of its parts, gum could not have the activity which violent poison has; and considering the small quantities in which myrrh is taken, and the opocalpasum could have been but in an inconsiderable proportion to the myrrh, to have killed, it must have been a very active poison indeed: Thirdly, these accidents from a known cause must have brought myrrh into disuse, as certainly as the Spaniards mixing arsenic with bark would banish that drug when we saw people die of it. Now this never was the case, it maintained its character among the Greeks and the Arabs, and so down to our days; and a modern physician, Van Helmont, thinks it might make man immortal if it could be rendered perfectly soluble in the human body. Galen then was mistaken as to the poisonous quality of the opocalpasum. The Greek physician knew little of the Natural History of Arabia, less still of that of Abyssinia, and we who have followed them know nothing of either.
This gum being put into water, swells and turns white, and loses all its glue; it very much resembles gum adragant in quality, and may be eaten safely. This specimen came from the Troglodyte country in the year 1771. The Sassa, the tree which produces the opocalpasum, does not grow in Arabia. Arabian myrrh is easily known from Abyssinian by the following method: Take a handful of the smallest pieces found at the bottom of the basket where the myrrh was packed, and throw them into a plate, and just cover them with water a little warm, the myrrh will remain for some time without visible alteration, for it dissolves slowly, but the gum will swell to five times its original size, and appear so many white spots amidst the myrrh.
Emfras, as I have said, is a large village something more than twenty miles south from Gondar, situated upon the face of a hill of considerable height above the lake Tzana, of which, and all its islands, it has a very distinct and pleasant view; it is divided from the lake by a large plain, near which is the island of Mitraha, one of the burying-places of the kings. The inhabitants of the lower town, close on the banks of the small river Arno, are all Mahometans, many of them men of substance, part of them the king’s tent-makers, who follow the camp, and pitch his tents in the field; the others are merchants to the myrrh and frankincense country, that is, from the east parallel of the kingdom of Dancali to the point Cape Gardefan, or Promontorium Aromatum; they also bring salt from the plains, on the west of the kingdom of Dancali, where fossile salt is dug; it is on the S. E. border of the kingdom of Tigré. These Mahometans trade also to the Galla, to the westward of the Nile; their principal commodity is myrrh and damaged cargoes of blue Surat cloth, which they unfold and clean, then stiffen them with gum, and fold them in form of a book as when they were new.
This gum, which is called Sassa, they at first brought from the myrrh country behind Azab, till ingenious and sagacious people had carried plants of the tree to their different villages, where they have it growing in great perfection, and more than supply the uses of the merchants.
This tree grows to a great height, not inferior to that of an English elm; that from which this draught was made was about two feet diameter; the gum grows on all sides of the trunk, in quantity enough almost to cover it, in form of large globes, and so it does on all the principal branches. These lumps are sometimes so large as to weigh two pound, though naturally very light.
The bark of the tree is thin and of a bluish colour, not unlike that of a cherry-tree when young, or rather whiter. The wood is white and hard, only the young branches which carry the flower are red. The leaves are joined to the sides of the small branches by a small pedicle of considerable strength, the leaves are two and two, or opposite to each other, and have no single leaf at the point; they are strongly varnished both on one side and the other, the back rather lighter than the foreside of the leaf. The branches that carry the leaves have about an inch of the stalk bare, where it is fixed to the larger branch. There are generally fourteen leaves, each of about three quarters of an inch long. At the top of the branch are knots out of which come three small stalks, bare for about an inch and a half, then having a number of small tubes, which, when they open at the top, put forth a long pistil from the bottom of the tube. The top of the tube, divided into five segments, or petals, arrives about one third up the pistil, and makes the figure of a calix or perianthium to it. From this tube proceeds a great number of very small capillaments of a pink colour, at the end of each of which hangs a purple stigma. At the top of this pistil is a large bunch of still finer fibres, or capillaments, with stigmata likewise, and at the end the pistil is rounded as if forming a fruit; without a very distinct drawing, it would be difficult to make a description that should be intelligible.
Nothing can be more beautiful, or more compounded, than the formation of this flower, though it has no odour; the head is composed of about thirty of these small branches now described, which make a very beautiful mass, and is of a pink colour of different shades. At sun-set, the leaves on each side of the branch shut face to face like the sensitive tribe. I never saw any seed or fruit that it bore, nor any thing like the rudiments of seed, unless it be that very small rotundity that appears at the end of the pistil, which seem to bear no proportion to so large a tree.
