Humano capiti cervicem pictor equinam
Jungere si velit, et varias inducere plumas,
Undique collatis membris—
I wish commentators would follow the example of our naturalists, who consider a plant as a distinct species until it has been proved on sure grounds that it is nothing else than a variety of a plant already characterized. I should not therefore affirm that the cinara and the carduus are the same, were I not able to produce the following incontestable proofs in support of my assertion.
In the first place, the Latins, Palladius and Pliny, give us the same account of the carduus that Columella and the Greeks do of the cinara. The former lost its prickles through cultivation603; its flowers were also of a purple colour604; it was propagated by seed and by shoots; it required frequent watering; and it was remarked that it throve better when the earth was mixed with ashes. Had not the carduus and the cinara been the same, Palladius and Pliny would have mentioned the latter; for we cannot suppose that they otherwise would have omitted a plant that formed a dish so much esteemed and so well-known among their countrymen. The latter claims to himself the merit of having passed over no one that was held in estimation. In the second place, Virgil has translated the word cynaros in a part of Sophocles now lost, by carduus605; thirdly, Athenæus says expressly, that the cinara was by the Latins named cardus and carduus606; and, lastly, the old glossaries explain cinara by carduus, as we are told by Salmasius. On these grounds, therefore, I am of opinion that the cinara and the carduus were the same.
We are informed by Apicius607 and Pliny608 in what manner the carduus was dressed by the ancient cooks. The latter gives directions for pickling it in vinegar; but neither of them tells us what part of it was eaten. Lister thinks that Apicius speaks of the tops of the young shoots, which, as far as I know, are parts of the artichoke never eaten at present. It is, however, worthy of remark, that the tops (turiones) of certain kinds of the thistle family of plants, and among these the common burr609, are in some countries dressed and eaten like asparagus. It is not improbable also that Pliny and Apicius may have meant the ribs of the leaves; though none of the ancients has taught us the art of binding up, covering with earth, and blanching the cinara or carduus. This, perhaps, was a new invention of the gardeners; and the cooks may have had other methods of rendering the ribs of the leaves tender and eatable. Had they meant the bottom of the calyx, they would not have omitted to give a circumstantial account of the preparation previous to its being pickled.
The Scolymus is by Pliny and Theophrastus reckoned to belong to the genus of the thistles. The former says, that, like most others of the same kind, the seeds were covered by a sort of wool (pappus). It had a high stem, surrounded with leaves, which were prickly, but which ceased to sting when the plant withered610. It flowered the whole summer through, and had often flowers and ripe seed at the same time; which is the case also with our artichoke plants. The calyx of the scolymus was not prickly611; the root was thick, black and sweet, and contained a milky juice. It was eaten both raw and cooked; and Theophrastus observes, as something very remarkable, that when the plant was in flower, or, as others explain the words, when it had finished blowing, it was most palatable. What renders this circumstance singular is, that most milky roots used for food lose their milk and become unfit to be eaten as soon as they have blown. This is the case with the goat’s beard, which is eatable only the first year.
The scolymus however is not the only plant which forms an exception; for the garden Scorzonera retains its milk, and continues eatable after it has bloomed, and as long as it has milk it may be used. According to Theophrastus and Pliny, the roots of the scolymus are eatable. On the other hand, Dioscorides says that the roots were not eaten, but the young leaves only: as he informs us, however, that they were dressed like asparagus, it would appear that he meant the young shoots612. Theophrastus expressly tells us, that, besides the roots, the flowers also were used as food; and he calls that which was eatable the pulpy part. We have, therefore, full proof that the ancients ate the tops of some plants in the same manner as we eat our artichokes.
It may however be asked, what kind of a plant was the scolymus? That it was different from the cinara is undoubtedly certain; for Dioscorides613 expressly distinguishes them; nor was it the eatable carduus, for Pliny compares it with the carduus, and says that it was characterized from the latter by having roots fit to be eaten. Stapel is of opinion that the scolymus is our artichoke; but this seems to me improbable, for the leaves and roots of the latter are not sweet, but harsh and bitter, and the calyx is prickly, which was not the case in the scolymus of Theophrastus. Besides, I find nothing in the whole description of the scolymus or in the accounts given us by the ancients of the cinara and carduus, that can be applied to our artichoke alone, and not to any other plant. It may be here replied, that it would be very difficult to ascertain plants from the names of the ancients, were such strong proofs required, because they had not the art of separating the different genera correctly, and of assigning to each certain characterizing marks. This I allow; and for that reason it is impossible to elucidate properly the Greek and Latin names of plants; but, in my opinion, it is better to confess this impossibility, than to deceive oneself with distant probabilities. Let the genus be ascertained when one cannot ascertain the species; let the order to which the plant belongs be determined when one cannot determine the genus; or, at least, let the class be assigned when there is sufficient authority to do so. The cinara, carduus and scolymus were therefore species of the thistle, of which the roots and young shoots, and also the bottom of the calyx of the last, were eaten. Were I appointed or condemned to form a new Latin dictionary, I should explain the article Scolymus in the following manner:—Planta composita, capitata. Caulis longus, obsitus foliis spinosis. Radix carnosa, lactescens, nigra, dulcis, edulis. Calyx squamis inermibus, disco carnoso, ante efflorescentiam eduli. Semina papposa. Turiones edules. This description, short as it is, contains every thing that the ancients have said in order to characterize that plant. It can, indeed, be understood only by those who are acquainted with the terms of botany; but what follows will require no explanation or defining of botanical names.
Should it be said that the scolymus must be our artichoke because no other plant of the thistle kind is known the bottom of the calyx of which is eatable, I would in answer observe:—First, other species may have been known in ancient times, which perhaps have been disused and forgotten since the more pleasant and delicious artichoke became known. It is certain that many old plants have in this manner been banished from our gardens by the introduction of new ones. Thus have common alexanders (Smyrnium olusatrum) fallen into neglect since celery was made known by the Italians, about the end of the seventeenth century; and so at present has the cultivation of winter-cresses (Erysimum barbarea), bulbous-rooted chærophyllum (Chærophyllum bulbosum), rocket (Brassica eruca), and others, been abandoned since better vegetables have been obtained to supply their place.
