So obscure is the ichthyology of the ancients, or so little care has been taken to explain it, that the question whether our carp were known to Aristotle, Pliny, and their contemporaries, cannot with any great degree of probability be determined. Besides, that subject is attended with much greater difficulties than the natural history of quadrupeds. Among four-footed animals there is a greater variety in their bodily conformation, which at any rate strikes the eye more, and can be more easily described than that of fishes, which in general are so like in shape, that an experienced systematic naturalist finds it sometimes difficult to determine the characters of the genera and species. It is not surprising therefore that the simple descriptions of the ancients, or rather the short accounts which they give us of fish, do not afford information sufficient to enable us to distinguish with accuracy the different kinds. Quadrupeds may terrify us by their ferocity, or endeavour to avoid us by shyness and craft; but it is still possible to observe their sexes, their age, and their habits, and to remark many things that are common to one or only a few species. Fishes, on the other hand, live in an element in which we cannot approach them, and which for the most part conceals them from our observation. The chase, since the earliest periods, and in modern times more than formerly, has been the employment of idle persons, who bestow upon it greater attention the fewer those objects are which can attract their curiosity or employ their minds: but fishing has almost always been the laborious occupation of poor people, who have no time to make observations, as they are obliged to follow it in order to find a subsistence; and mankind in general seldom see fish except on their tables or in collections of natural history. On this account those properties of fish by which their species could be determined, were less known. The descriptions of four-footed animals which have been handed down to us from the time of the Greek and Roman writers, give us, at any rate, some information; but from those of fishes, which are more uncommon, we can scarcely derive any; unless one were as acute or easy of belief as many collectors of petrefactions, who imagine that they can distinguish each species of fish in the impressions which they see in stones. More however might be done towards elucidating the ichthyology of the ancients than has hitherto been attempted. It would be necessary only to make a beginning by collecting the species and names which can with certainty be determined, together with the authorities, and separating them from the rest; and an abstract should be formed of what is said in the ancients respecting the unknown species, or whatever may in any measure serve to make us acquainted with them; but mere conjectures ought never to be given as proofs, nor ought the opinions of commentators, or the explanations of dictionaries to be adopted without sufficient grounds. If these are to be believed without further examination, the names cyprini and lepidoti must be considered as those of carp; and the proposed question would be soon answered: but that opinion has scarcely probability in its favour when one searches after proofs.

I shall not here lay before the reader everything completely that the ancients have said respecting the cyprini, and which is in part so corrupted by transcribers, that no certain meaning can be drawn from it. Were I to treat of the ichthyology of the ancients, it might be necessary; but as that is not the case, I shall only quote such parts of it as have been employed by Rondelet and others to prove that they were our carp. Their principal grounds seem to be, that among all the fish of the ancients no others occur which can with any probability be considered as carp. If the cyprini therefore were not carp, these must not have been named by the ancients; and that undoubtedly will not readily be admitted. It is well known what a high value the ancients, particularly the Orientals, set upon fish, of which they had a great variety; and it appears that they preferred them to all dishes prepared from four-footed animals or fowls. Fish seem to have been the choicest delicacies of voluptuaries, and in that respect they are oftener mentioned by historians than fowls. Physicians also, to whom the most sumptuous tables have in all ages been of the greatest benefit, speak of fish oftener in their writings than of dishes made of the flesh of other animals. In the ancient cookery, the number of dishes prepared from fish is indeed great in comparison of those dressed from fowls. Turdi and attagines are much praised; but had pheasants, snipes, partridges, and others, been as much esteemed then as they are now, these would not have been forgotten, or would have occurred oftener. Fish at present form the principal food in Greece, as well as at Constantinople, and a great abundance and variety of them may be found there in the markets; but fowls which have been caught or shot are seldom exposed for sale. When the Egyptian and Greek monks wished to distinguish themselves by abstinence and temperance, they denied themselves all kinds of fish, as the richest delicacies, in the same manner as pretended devotees among the Europeans deny themselves flesh. But though all this may be true, it does not prove that our carp must occur in the writings of the ancients. The Roman voluptuaries, indeed, left very little untried that was likely to gratify their appetite; but it was impossible for them to make a trial of everything. There may have been particular reasons which prevented them from meeting with carp; and who will venture to affirm that all the knowledge of the ancients must be contained in those few of their writings which have been preserved to us by accidents?

If one, freed from these prejudices, should now ask why the cyprinus must be our carp, the answer will be, because what we read of the tongue and scales of the cyprini cannot be applied with so much propriety to any species of fish as to the Cyprinus carpio of LinnÆus. Aristotle informs us that the cyprini had properly no tongue, but that their soft fleshy palate might very readily be taken for one112. AthenÆus affirms that they had a tongue, but that it lay in the upper part of the mouth or palate; and in confirmation of this he refers to Aristotle113. This assertion of AthenÆus however is very dubious; for these words are not to be found in the works of Aristotle which have been preserved, though the same meaning might be indeed forced, in case of necessity, from the passage first quoted. It is possible that AthenÆus, as Casaubon114 has already conjectured, may here, as well as in other parts, allude to some book of Aristotle not now extant. Besides, he calls the fish of which he speaks, not cyprinus, but cyprianus; and a question therefore arises, whether he may not have meant some other kind. This much at any rate appears certain from the passage of Aristotle, that the cyprinus had a thick fleshy palate; and that indeed is the case with our carp, so that the head, on account of the delicacy and agreeable taste of the palate, is reckoned the most relishing part. By that circumstance however nothing is proved; as it is not peculiar to carp alone, but common to every species of the same family, such as the bream, tench, &c. Fish of this kind, says Bloch, have properly no tongue; that which appears to be one is merely a cartilaginous substance which projects through those band-like parts that enclose it on each side. This proof would have more weight, did we find it related, that in the time of Aristotle, the tongue was considered as an exquisite morsel: but that is not mentioned; and H. Krunitz is mistaken, when he says that Heliogabalus, to satisfy his luxurious appetite, was induced to try a fricassee of the tongues of carp: it consisted only of the tongues of peacocks and nightingales115. Had the ancients really used carp on their tables, we must have ascribed to them the discovery of these delicious fish.

The other proof which is brought from the scales consists in what is said by Dorion, in AthenÆus116, that the cyprianus was called also by some lepidotus, or scaly. As nearly all fish have scales, the scales of this species must have been extremely large, as they got that name by way of eminence; and it must be indeed allowed, that the above epithet would suit our carp exceedingly well, as their scales are very large. But this circumstance alone proves nothing, as the Mullus and Mugil have still larger scales; and to the first genus belonged one of the fish most esteemed by the ancients117. Strabo mentions the lepidotus among the sacred fish of the Nile; but whether it be the same as that of which Dorion speaks, cannot be determined. It is certain that the Nile contains carp still; for Norden saw them caught at the waterfall near Essuane, which is the ancient Syene. Did we know that the modern Greeks at present call carp cyprini, this would prove more; for it is an undoubted fact that the ancient names have for the most part been retained in Greece. We are assured by Massarius118, that the Greeks still use the name cyprinus; but Gyllius says that it is employed only by a few: and this is confirmed by Bellon, who mentions all the names of carp which he heard in Greece, and which are entirely different from the ancient119; but he adds, that carp in Ætolia are still called cyprini. Both the before-mentioned circumstances respecting the cyprini agree extremely well with our carp; but as they will suit other kinds equally well, they afford no complete proof, but only a probability which amounts to this, that among the large-scaled fish, carp in particular have a fleshy palate; and it is readily admitted that the ancients were acquainted with all kinds, and chose names for them with more foundation than is done at present.

In opposition to this probability it may be said that Oppian and Pliny reckon the cyprini among the sea-fish, to which kind our carp do not belong. This reply however, which some have indeed made, is not of great weight. In the first place, both these writers seem to have been in an error; for what Pliny says of the cyprini is evidently taken from Aristotle, and the latter does not tell us that these fish live in the sea, but rather the contrary. The Roman author, as Dalechamp remarks, added the words in mari, if they were not added by some transcriber. Oppian as a poet does not always adhere strictly to truth; and he makes more of the freshwater fish of Aristotle to be inhabitants of the sea. In the second place, I consider the distinction made between sea-fish, freshwater fish and those kept in ponds, to be not always very certain or well founded. Who knows whether the greater part of the last may not have been originally sea-fish? This is the more probable in regard to carp, as Professor Foster says that carp are sometimes caught in the harbour at Dantzic120.

In order to answer the question here proposed, another point may be considered. As all nations at present give these fish the same name, it is probable that it was brought with them from that country where they were first found, and from which they were procured. Cassiodorus, who lived in the sixth century, is the oldest author as yet known in whom that name has been observed121. In a passage where he speaks of the most delicate and costly fish, which at that time were sent to the tables of princes, he says, “Among these is the carpa, which is produced in the Danube.” In the earliest Latin translation of Aristotle, the word cyprinus, as Camus says, is expressed by carpra. In the thirteenth century this fish was called by Vincentius de Beauvais122 carpera, and by CÆsarius carpo; and it is highly probable that both these names allude to our carp. By the above passage of Cassiodorus, the opinion that these fish were the cyprini of the ancients obtains a new, but at the same time a very feeble proof; for the cyprinus was found also in the Danube, as we learn from Ælian123, who among the fish of the Ister, mentions black cyprini; and these, according to the conjecture of Professor Schneider, were the black fish of the Danube which Pliny considers as unhealthful or poisonous, and like which there were some in Armenia. Our carp indeed are not poisonous, but Pliny alludes to a particular variety, and what he says was only report, to which something must have given rise, as also to the idea of carp with a death’s head, and the head of a pug-dog, as some have been represented by writers of the sixteenth century. The carpo of CÆsarius appears to have been our carp, because its scales had a very great resemblance to those of the latter; for we are told in the work already quoted, that the devil, once indulging in a frolic, appeared in a coat of mail, and had scales like the fish carpo. The carpera of Vincent de Beauvais is still less doubtful, as the same craft in avoiding rakes and nets is ascribed to that fish as is known to be employed by our carp. Sometimes they thrust their heads into the mud and suffer the net to pass over them; and sometimes they join the head and tail together, and separating them suddenly, throw themselves towards the surface of the water, and springing often four or five feet above the net, make their escape.

But whence did this name arise? The origin assigned by Vincentius, or the anonymous author of the lost books De Natura Rerum, like another mentioned in ridicule by Gesner, is too silly to be repeated. More learned at any rate is the derivation of Menage, who traces it from cyprinus, which was afterwards transformed into cuprinus, cuprius, cuprus, cupra, curpa, and lastly into carpa. For my part, I am more inclined to derive it from a dialect which was spoken on the banks of the Danube, and to believe that it was brought with the fish from the southern part of Europe; but I am too little acquainted with that dialect to be able to render my conjecture very probable; and the etymologists I consulted, such as Wachter, Ihre, Johnson, &c., afforded me no assistance. Fulda gave me some hopes, as he allows the word to be of German extraction; but I must confess that his derivation is too far-fetched, and like the chemistry of the adepts, to me not perfectly intelligible.

It may perhaps not be superfluous here to observe that one must not confound carpa and carpo, or our carp, with carpio. The latter belongs to the genus of the salmon and trout; and in the LinnÆan system is called Salmo carpio. It is found chiefly in the Lago di Garda, the ancient Lacus Benacus, on the confines of Tyrol. The oldest account of this fish is to be found in works of the sixteenth century, such as the poems of Pierius Valerianus, and in Jovius de Piscibus. According to LinnÆus, it is found in the rivers of England; but that is false. This celebrated naturalist suffered himself to be misled by Artedi, who gives the char or chare, mentioned by Camden in his description of Lancashire, as the Salmo carpio. Pennant however, by whom it is not mentioned among the English fish, says expressly that the char is not the carpio of the Lago di Garda, but rather a variety of the Salmo alpinus124.

That our carp were first found in the southern parts of Europe, and conveyed thence to other countries, is undoubtedly certain. Even at present they do not thrive in the northern regions, and the further north they are carried the smaller they become125. Some accounts of their transportation are still to be found. If it be true that the Latin poem on the expedition of Attila is as old as the fifth or sixth century, and if the fish which Walther gave to the boatman who ferried him over the Rhine, and which the latter carried to the kitchen of Gunther king of the Franks, were carp, this circumstance is a proof that these fish had not been before known in that part of France which bordered on the Rhine126. The examination of this conjecture I shall however leave to others. D’Aussy quotes a book never printed, of the thirteenth century, entitled Proverbes, and in which is given an account of the best articles produced at that time by the different parts of the kingdom, and assures us that a great many kinds of fish were mentioned in it, but no carp, though at present they are common all over France.

It appears also that there were no carp in England in the eleventh century, at least they do not occur in the Anglo-Saxon Dictionary of Ælfric, who in 1051 died archbishop of York127. We are assured likewise that they were first brought into the kingdom in the fifth year of the reign of Henry VIII., or in 1514, by Leonard Mascal of Plumsted in Sussex128. What we read in the LinnÆan System, that these fish were first brought to England about the year 1600, is certainly erroneous. Where that celebrated naturalist, under whom I had the pleasure of studying, acquired this information, I do not know.

Denmark is indebted for these fish to that celebrated statesman Peter Oxe, who introduced them into the kingdom as well as cray-fish, and other objects for the table. He died in the year 1575.

We are told that these fish were brought from Italy to Prussia, where they are at present very abundant, by a nobleman whose name is not mentioned. This service however may be ascribed with more probability to the upper burg-grave, Caspar von Nostiz, who died in 1588, and who in the middle of the sixteenth century first sent carp to Prussia from his estate in Silesia, and caused them to be put into the large pond at Arensberg not far from Creuzburg. As a memorial of this circumstance, the figure of a carp, cut in stone, was shown formerly over a door at the castle of Arensberg. This colony must have been very numerous in the year 1535, for at that period carp were sent from KÖnigsberg to Wilda, where the archduke Albert then resided. At present (1798) a great many carp are transported from Dantzic and KÖnigsberg to Russia, Sweden, and Denmark. It appears to me probable that these fish after that period became everywhere known and esteemed, as eating fish in Lent and on fast-days was among Christians considered to be a religious duty, and that on this account they endeavoured to have ponds stocked with them in every country, because no species can be so easily bred in these reservoirs.

I shall observe in the last place, that the Spiegel-carpen, mirror-carp, distinguished by yellow scales, which are much larger, though fewer in number, and which do not cover the whole body, are not mentioned but by modern writers. Bloch says that they were first described by Johnston under the name of royal carp. The passage where he does so I cannot find; but in plate xxix. there is a bad engraving, with the title Spiegel-karpen, which however have scales all over their bodies, and cannot be the kind alluded to. On the other hand, the Spiegel-karpen are mentioned by Gesner, who, as it appears, never saw them. In my opinion, Balbinus, who wrote in the middle of the sixteenth century, was the first person who gave a true and complete description of them; and according to his account, they seem to have come originally from Bohemia. The first correct figure of them is to be found in Marsigli.
