Fishes do not thrive in cold places, and those fishes suffer most in severe [30] winters that have a stone in their head, as the chromis, the basse, the sciaena, and the braize; for owing to the stone they get frozen with the cold, and are thrown up on shore.
Whilst rain is wholesome for most fishes, it is, on the contrary, unwholesome [602a1] for the mullet, the cephalus, and the so-called marinus, for rain superinduces blindness in most of these fishes, and all the more rapidly if the rainfall be superabundant. The cephalus is peculiarly subject to this malady in severe winters; [5] their eyes grow white, and when caught they are in poor condition, and eventually the disease kills them. It would appear that this disease is due to cold even more than to an excessive rainfall; at all events, in many places and more especially in [10] shallows off the coast of Nauplia, in the Argolid, a number of blind fishes have been caught in seasons of severe cold. The gilthead also suffers in winter; the acharnas suffers in summer, and loses condition. The coracine is exceptional among fishes in deriving benefit from drought, and this is due to the fact that heat and drought are [15] apt to come together.
Particular places suit particular fishes: those at home off shore or in the deep sea thrive in those places; those which are ambivalent thrive in both. Some fishes will thrive in one particular spot, and in that spot only. As a general rule it may be said that places abounding in weeds are wholesome; at all events, fishes caught in such places are exceptionally fat: that is, such fishes as inhabit all sorts of localities [20] as well. The fact is that weed-eating fishes find abundance of their special food in such localities, and carnivorous fish find an unusually large number of smaller fish. It matters also whether the wind be from the north or south: the longer fish thrive better when a north wind prevails, and in summer at one and the same spot more long fish will be caught than flat fish with a north wind blowing. [25]
The tunny and the sword-fish are infested with a parasite about the rising of the dog-star; that is to say, about this time both these fishes have a grub beside their fins that is nicknamed the ‘gadfly’. It resembles the scorpion in shape, and is about the size of the spider. So acute is the pain it inflicts that the sword-fish will sometimes leap as high out of the water as a dolphin; in fact, it often falls into a [30] boat. The tunny delights more than any other fish in the heat of the sun. It will make for the sand near to shore because of the warmth, or will, because it is warm, disport [602b1] itself on the surface of the sea.
The fry of little fishes escape by being overlooked, for it is only the larger ones that large fish pursue. The greater part of the spawn and the fry of fishes is destroyed by the heat of the sun, for whatever of them the sun reaches it spoils. [5]
Fishes are caught in greatest abundance before sunrise and after sunset, or, speaking generally, just about sunset and sunrise. Fishermen haul up their nets at these times, and speak of the hauls then made as timely. The fact is, that at these times fishes are particularly weaksighted; at night they are at rest, and as the light [10] grows stronger they see comparatively well.
We know of no pestilential malady attacking fishes, such as those which attack man, and horses and oxen among the quadrupedal vivipara, and certain other animals, domesticated and wild; but fishes do seem to suffer from sickness; and [15] fishermen infer this from the fact that at times fishes in poor condition, and looking as though they were sick, and of altered colour, are caught in a large haul of well-conditioned fish of their own species. So much for sea-fishes.
20 · River-fish and lake-fish also are exempt from diseases of a pestilential [20] character, but certain species are subject to special maladies. For instance, the sheat-fish just before the rising of the dog-star, owing to its swimming near the surface of the water, is liable to sunstroke, and is paralysed by a loud peal of thunder. The carp is subject to the same eventualities, but in a lesser degree. The sheat-fish is destroyed in great quantities in shallow waters by the serpent called the [25] dragon. In the balerus and tilon a worm is engendered about the rising of the dog-star, that sickens these fish and causes them to rise towards the surface, where they are killed by the excessive heat. The chalcis is subject to a very violent malady; lice are engendered underneath their gills in great numbers, and cause destruction among them; but no other species of fish is subject to any such malady. [30]
Mullein kills fish; that is why fishermen use mullein in rivers and ponds—by the Phoenicians it is made use of also in the sea. [603a1]
There are two other methods employed for catching fish. In winter fishes emerge from the deep parts of rivers—and at all seasons fresh water is tolerably cold. A trench accordingly is dug leading though dry ground into a river, and [5] wattled at the river end with reeds and stones, an aperture being left in the wattling through which the river water flows into the trench; when the frost comes on the fish can be taken out of the trench in weels. Another method is adopted in summer and winter alike. They run across a stream a dam composed of rushwood and stones, [10] leaving a small open space, and in this space they insert a weel in which they catch them when they have removed the stones.25
Shell-fish, as a rule are benefited by rainy weather. The purple murex is an exception; if it be placed on a shore near to where a river discharges, it will die [15] within a day after tasting the fresh water. The murex lives for about fifty days after capture; during this period they feed off one another, as there grows on the shell a kind of sea-weed or sea-moss; if any food is thrown to them during this period, it is said to be done to make them weigh more.
To shell-fish in general drought is unwholesome. During dry weather they [20] decrease in size and degenerate in quality; and it is during such weather that the red scallop is found in more than usual abundance. In the Pyrrhaean Strait the scallop was exterminated, partly by the dredging-machine used in their capture, and partly by long-continued droughts. Rainy weather is wholesome to the generality of shell-fish owing to the fact that the sea-water then becomes exceptionally sweet. In [25] the Euxine, owing to the coldness of the climate, shell-fish are not found; nor yet in rivers, excepting a few bivalves. Univalves are very apt to freeze to death in extremely cold weather. So much for animals that live in water.
21 · To turn to quadrupeds, the pig suffers from three diseases, one of which is called branchos, a disease attended with swellings about the windpipe and the [603b1] jaws. It may break out in any part of the body; very often it attacks the foot, and occasionally the ear; the neighbouring parts also soon rot, and the decay goes on until it reaches the lungs, when the animal succumbs. The disease develops with [5] great rapidity, and the moment it sets in the animal gives up eating. The swineherds know but one way to cure it, namely, by complete excision, when they detect the first signs of the disease. There are two other diseases, which are both alike termed craurus. The one is attended with pain and heaviness in the head, and this is the commoner of the two, the other with diarrhoea. The latter is incurable, the former is [10] treated by applying wine to the snout and rinsing the nostrils with wine. Even this disease is very hard to cure; it has been known to kill within three or four days. The animal is chiefly subject to branchos when it gets extremely fat, and when the heat has brought a good supply of figs. The treatment is to feed on mulberries, to give [15] repeated warm baths, and to lance the under part of the tongue.
Pigs with flabby flesh are subject to measles about the legs, neck, and shoulders, for the pimples develop chiefly in these parts. If the pimples are few in number the flesh is comparatively sweet, but if they be numerous it gets watery and flaccid. The symptoms of measles are obvious, for the pimples show chiefly on the [20] under side of the tongue, and if you pluck the bristles off the chine the skin will appear suffused with blood, and further the animal will be unable to keep its hind-feet at rest. Pigs never take this disease while they are mere sucklings. The pimples may be got rid of by tiphe; and this is useful as food too. The best food for [25] rearing and fattening pigs is chickpeas and figs, but the one thing essentia
l is to vary the food as much as possible, for this animal, like animals in general, delights in a change of diet; and it is said that one kind of food blows the animal out, that another superinduces flesh, and that another puts on fat, and that acorns, though liked by the animal, render the flesh flaccid. Besides, if a pregnant sow eats acorns in great [604a1] quantities, it will miscarry, as is also the case with the ewe—for acorns quite plainly have that effect on ewes. The pig is the only animal known to be subject to measles.
22 · Dogs suffer from three diseases; rabies, quinsy, and sore feet. Rabies [5] drives the animal mad, and any animal whatever, excepting man, will take the disease if bitten by a dog so afflicted; the disease is fatal to the dog itself, and to any animal it may bite, man excepted. Quinsy also is fatal to dogs; and only a few dogs recover from disease of the feet. The camel, like the dog, is subject to rabies. The [10] elephant, which is reputed to enjoy immunity from all other illnesses, is occasionally subject to flatulency.
23 · Cattle in herds are liable to two diseases, foot-sickness and craurus. In the former their feet suffer from eruptions, but the animal recovers from the disease [15] without even the loss of the hoof. It is found of service to smear the horny parts with warm pitch. In craurus, the breath comes warm at short intervals; in fact, craurus in cattle answers to fever in man. The symptoms of the disease are drooping of the ears [20] and disinclination for food. The animal soon succumbs, and when the carcase is opened the lungs are found to be rotten.
24 · Horses out at pasture are free from all diseases excepting disease of the feet. From this disease they sometimes lose their hooves; but after losing them they [25] grow them soon again, for as one hoof is decaying it is being replaced by another. Symptoms of the malady are a sinking in and wrinkling of the lip in the middle under the nostrils, and a twitching of the right testicle.
Stall-reared horses are subject to very numerous forms of disease. They are liable to a disease called ‘eileus’. Under this disease the animal trails its hind-legs [604b1] under its belly so far forward as almost to fall back on its haunches; if it goes without food for several days and then turns rabid, it may be of service to draw blood, or to castrate the male. The animal is subject also to tetanus: the veins get rigid, as also the head and neck, and the animal walks with its legs stretched out [5] straight. The horse suffers also from abscesses. Another painful illness afflicts them called the ‘barley-surfeit’. The symptoms are a softening of the palate and heat of the breath; it is incurable, unless the animal recovers spontaneously.
[10] There is also a disease called nymphia, in which the animal is said to be possessed and droops its head on hearing flute-music; if during this ailment the horse be mounted, it will run off at a gallop until it is pulled. Even with this rabies in full force, it preserves a dejected spiritless appearance; some of the symptoms are a throwing back of the ears followed by a projection of them, great languor, and [15] panting. Heart-ache also is incurable, of which the symptom is pain and loosening of the bowels; and so is displacement of the bladder, which is accompanied by a retention of urine and a drawing up of the hooves and haunches. Neither is there any cure if the animal swallow the grape-beetle, which is about the size of the [20] knuckle-beetle. The bite of the shrewmouse is dangerous to other draught animals as well; it is followed by boils. The bite is all the more dangerous if the mouse be pregnant when she bites, for the boils then burst, but do not burst otherwise. The cicigna—called ‘chalcis’ by some, and ‘zignis’ by others—either causes death by its [25] bite or, at all events, intense pain; it is like a small lizard, with the colour of the blind snake. In point of fact, according to experts, the horse and the sheep have pretty well as many ailments as the human species. The drug realgar is extremely injurious to a horse, and to all draught animals; it is given to the animal in a solution of water, the liquid being filtered. The mare when pregnant is apt to miscarry when disturbed by the odour of an extinguished candle; and a similar accident happens occasionally [605a1] to women in their pregnancy. So much for the diseases of the horse.
The so-called hippomanes grows, as they say, on the foal, and the mare nibbles it off as she licks and cleans the foal. All the curious stories connected with the [5] hippomanes are due to old wives and to the venders of charms. What is called the ‘polium’ is, as all the accounts state, delivered by the mother before the foal appears.
A horse will recognize the neighing of any other horse with which it may have fought at any previous period. The horse delights in meadows and marshes, and [10] likes to drink muddy water; in fact, if water be clear, the horse will trample in it to make it turbid, will then drink it, and afterwards will wallow in it. The animal is fond of water and of bathing—and this explains the peculiar constitution of the hippopotamus. In regard to water the ox is the opposite of the horse; for if the water [15] be impure or cold, or mixed up with alien matter, it will refuse to drink it.
25 · The ass suffers chiefly from one particular disease which they call ‘melis’. It arises first in the head, and a clammy humor runs down the nostrils, thick [20] and red; if it stays in the head the animal may recover, but if it descends into the lungs the animal will die. Of all animals of its kind it is the least capable of enduring extreme cold, which circumstance will account for the fact that the animal is not found on the shores of the Euxine, nor in Scythia.
26 · Elephants suffer from flatulence and then can void neither solid nor [25] liquid residuum. If the elephant swallows earth it suffers from relaxation; but if it goes on taking it steadily, it will experience no harm. From time to time it takes to swallowing stones. It suffers also from diarrhoea: in this case they administer draughts of lukewarm water and dip its fodder in honey, and either one or the other prescription will prove a costive. When they are exhausted from insomnia, they will [30] be restored to health if their shoulders be rubbed with salt, olive-oil, and warm water; when they have aches in their shoulders they will derive great benefit from [605b1] the application of roast pork. Some elephants like olive-oil, and others do not. If there is a bit of iron in the inside of an elephant it is said that it will pass out if the animal takes a drink of olive-oil; if the animal refuses olive-oil, they soak a root in the oil and give it the root to swallow. [5]
So much, then, for quadrupeds.
27 · Insects, as a general rule, thrive best in the time of year in which they come into being, especially if the season be moist and warm, as in spring.
In bee-hives are found creatures that do great damage to the combs; for instance, the grub that spins a web and ruins the honey-comb: it is called the [10] ‘cleros’, and by some the ‘pyraustes’. It engenders an insect like itself, of a spider-shape, and brings disease into the swarm. There is another insect resembling the moth that flies about a lighted candle; this creature engenders a brood full of a fine down. It is never stung by a bee, and can only be got out of a hive by fumigation. [15] A caterpillar also is engendered in hives [called a ‘borer’]26 with which the bee never interferes. Bees suffer most when flowers are covered with mildew, or in seasons of drought.
All insects die if they be smeared over with oil; and they die all the more [20] rapidly if you smear their head with the oil and lay them out in the sun.
28 · Variety in animal life may be produced by variety of locality: thus in one place an animal will not be found at all, in another it will be small, or short-lived, or will not thrive. Sometimes this sort of difference is observed in closely [25] adjacent districts. Thus, in the territory of Miletus, in one district cicadas are found while there are none in the district adjoining; and in Cephalenia there is a river on one side of which the cicada is found and not on the other. In Pordoselene there is a public road on one side of which the weasel is found but not on the other. In Boeotia [30] the mole is found in great abundance in the neighborhood of Orchomenus, but there are none in Lebadia, though it is in the immediate vicinity, and if a mole be [606a1] transported from the one district to the other it will refuse to burro
w in the soil. The hare cannot live in Ithaca if introduced there; in fact it will be found dead, turned towards the point of the beach where it was landed. The winged ant is not found in [5] Sicily; the croaking frog has only recently appeared in the neighbourhood of Cyrene. In the whole of Libya there is neither wild boar, nor stag, nor wild goat; and in India, according to Ctesias—no very good authority, by the way—there are no swine, wild or tame, but animals that are devoid of blood and tessellates are all of [10] immense size there. In the Euxine there are no cephalopods nor testaceans, except a few here and there; but in the Red Sea all the testaceans are exceedingly large. In Syria the sheep have tails a cubit in breadth; the goats have ears a span and a palm [15] long, and some have ears that flap down to the ground; and the cattle have humps on their shoulders, like the camel. In Lycia goats are shorn, just as sheep are in all other countries. In Libya horned animals are born with horns, and not the ram only, [20] as Homer words it, but others as well; in Pontus, on the confines of Scythia, it is the other way about—they are born without horns.
