The story of how the _Lupus_ comes to his death by the Prawn can be read in Oppian[454] and in Ælian.[455] The fish, ever voracious, takes the prawns into his mouth by the thousand; these, unable to resist or retreat, jump about and puncture his throat and jaws so seriously that he soon dies of poison and suffocation. Pliny (IX. 17), it has been claimed, under the word _Esox_ intends our _Esox lucius_; but Cuvier maintains, and rightly, that his _Esox_ signifies some very large fish, perhaps a Tunny. Sulpicius Severus, a presbyter who lived in Aquitania (_c._ 365-425 A.D.) and penned an enthusiastic _Life of S. Martin of Tour_,[456] writes: “ad primum jactum reti permodico immanem Esocem extraxit.” It is not for me to discuss or decry this amazing statement of a very small net holding this monstrous _Esox_. But as the growth of a Pike under the most favourable circumstances is probably not more than 2 lbs. a year for twelve years when usually it lessens materially, I do suggest that the adjective _immanem_ is hardly applicable (unless St. Martin’s biographer, perhaps also a fisherman, has lapsed unconsciously into a “fish story”) to a fish of about 20 or 30 lbs., and so would seem to confirm Cuvier.[457] Pike, Carp, and Grayling were not apparently indigenous in England. They were introduced from the Continent at some undetermined date by one of the earlier religious orders for the better keeping of Fast Days, which as enjoined by the Church, even in Queen Elizabeth’s time, amounted to no less than 145 in number.[458] The Pike, though known in the thirteenth century, was very scarce. Its price (as fixed by Edward I.) doubled that of the salmon, and exceeded ten times over that of either the turbot or cod. Even as late as the Reformation a large pike fetched as much as a February lamb, and a very small pickerel more than a fat capon. This ratio of prices recalls the rebuke administered by Cato the Censor to those prodigal Romans who were willing to pay more for a dish of fish than for a whole ox. In view of the necessity for fish on the fast days, which claimed nearly half the year, the situation of twenty Sees (two Archbishoprics and eighteen Bishoprics) out of twenty-seven on what were then salmon rivers can hardly have been a geographical accident. The Carp must also have been a scarce fish in Tudor England. Dame Juliana Berners writes, “Ther be fewe in Englande.” Holinshed, _à propos_ of its scarcity in the Thames, states, “It is not long since that kind of fish is brought over into England.” Leonard Mascall, however, in his _Book of Fishinge_ (1596), credits a Mr. Mascall of Plumstead in Essex with the introduction of carp. A hackneyed couplet, frequently quoted for the purpose of establishing the date at which carp and pike were introduced, but so full of mistakes as to be worthless, runs thus: “Turkies, Carps, Hops, Pickerell, and Beer, Came into England all in one year.”
