We now come to the practice of catching Fish by the net, a custom to which the various Scriptural writers frequently refer, sometimes in course of historical narrative, and sometimes by way of allegory or metaphor. The reader will remember that the net was also used on land for the purpose of catching wild animals, and that many of the allusions to the net which occur in the Old Testament refer to the land and not to the water.
The commonest kind of net, which was used in the olden times as it is now, was the casting-net. This kind of net is circular, and is loaded all round its edge with weights, and suspended by the middle to a cord. When the fisherman throws this net, he gathers it up in folds in his arms, and, with a peculiar swing of the arms, only to be learned by long practice, flings it so that it spreads out and falls in its circular form upon the surface of the water. It rapidly sinks to the bottom, the loaded circumference causing it to assume a cup-like form, enclosing within its meshes all the Fish that happen to be under it as it falls. When it has reached the bottom, the fisherman cautiously hauls in the rope, so that the loaded edges gradually approach each other, and by their own weight cling together and prevent the Fish from escaping as the net is slowly drawn ashore.
This kind of net is found, with certain modifications, in nearly all parts of the world. The Chinese are perhaps supreme in their management of it. They have a net of extraordinary size, and cast it by flinging it over their backs, the huge circle spreading itself out in the most perfect manner as it falls on the water.
At the present day, when the fishermen use this net they wade into the sea as far as they can, and then cast it. In consequence of this custom, the fishermen are always naked while engaged in their work, wearing nothing but a thick cap in order to save themselves from sun-stroke. It is probable that on the memorable occasion mentioned by St. John, in chap. xxi., all the fishermen were absolutely, and not relatively naked—i.e. that they wore no clothes at all, not even the ordinary tunic.
That a great variety of nets was used by the ancient Jews is evident from the fact that there are no less than ten words to signify different kinds of net. At the present day we have very great difficulty in deciding upon the exact interpretation of these technical terms, especially as in very few cases are we assisted either by the context or by the etymology of the words. It is the same in all trades or pursuits, and we can easily understand how our own names of drag-net, seine, trawl, and keer-drag would perplex any commentator who happened to live some two thousand years after English had ceased to be a living language.
Four or five of the Hebrew words give no clue whatever, being simply derived from a root that signifies weaving, and that therefore merely indicates the fact that the articles in question are nets. Some of them are derived from a word which signifies lying in wait, and another from a word which signifies catching or seizing.
The translators who rendered the Hebrew into the familiar form of the Septuagint either were unable to distinguish between the various Hebrew terms, or did not think that any discrimination was needed, inasmuch as they sometimes render the same Hebrew word by several Greek equivalents, and sometimes use the same Greek word to express several Hebrew terms.
When we come to the New Testament, we find a certain feeling of relief, because the three words used to signify different kinds of nets are easily understood.
There is, for example, the amphiblêstron (αμφίβληστρον), which is undoubtedly a casting net, as is signified by the etymology of the word, which is derived from two Greek words signifying to cast around. This word is used by Herodotus in a sort of parable related by Cyrus to the Ionians and Æolians, who had refused to revolt from Crœsus when Cyrus asked them to do so; but, when they found he was sure to be their master, they sent an embassy to ask to be admitted among his subjects on the same terms which they had enjoyed when under the rule of Crœsus.
When the embassy came before Cyrus, he only answered them with a parable: "A piper, seeing some fishes in the sea, began to pipe, expecting that they would come ashore; but, finding his hopes disappointed, he took a casting-net, and enclosed a great number of fishes, and drew them out. When he saw them leaping about, he said to the fishes, 'Cease your dancing, since when I piped you would not come out and dance.'"
