Therefore, when the young die I am reminded of a strong flame extinguished by a torrent; but when old men die it is as if a fire had gone out without the use of force and of its own accord, after the fuel had been consumed; and, just as apples when they are green are with difficulty plucked from the tree, but when ripe and mellow fall of themselves, so, with the young, death comes as a result of force, while with the old it is the result of ripeness. To me, indeed, the thought of this “ripeness” for death is so pleasant, that the nearer I approach death the more I feel like one who is in sight of land at last and is about to anchor in his home port after a long voyage.

[Itaque adulescentes mihi mori sic videntur, ut cum aquae multitudine flammae vis opprimitur, senes autem sic, ut cum sua sponte nulla adhibita vi consumptus ignis exstinguitur; et quasi poma ex arboribus, cruda si sunt, vix evelluntur, si matura et cocta, decidunt, sic vitam adulescentibus vis aufert, senibus maturitas; quae quidem mihi tam iucunda est, ut, quo propius ad mortem accedam, quasi terram videre videar aliquandoque in portum ex longa navigatione esse venturus.]

And by that the adolescentes & yong men as me semyth dyen like as old men which quencheth a strong & a right grete fflame of fyre by castyng in of moche watir, and olde men dyen as a fyre which stynteth and wasteth itself or as a candel & the matche in a lampe of oyle consumith withoute doyng violence & withoute any force & strength. I make eftsonys anothir comparison of deth whiche comyth both to yong & olde men ffor as the appils & othir fruytes hangyng on the trees be by force plucked in the meanetyme whiles they be rawe & newe & when they be ripe & melowe by the heete of the sonne they fallen of with their free & playne will & so the deth takith awey by hir violente force the life of yong men and the ripnesse of olde age takith awey the life of olde men softely and withoute force. And this deth whiche comith by ripnesse of long age is so ioyfull and so agreable to me in so moche as I shall applye and come more nygh to it in a convenient season. The deth is also to me noon othirwise ioyfull or agreable than shuld be to me the deye londe if me thought that I shulde see it when I seyle in a ship or swymme in the see to the porte or havyn. And that it were likly that I shuld come to the porte or havyn aftir that I have sey∣led and vyaged long upon the see. That is to witt that deth which comith to the wise man aftir long age is like the porte or haven that men see from ferr in seylyng upon the see whiche doth grete ioye when men be upon the river into the haven warde and to have takyn their porte salve ffor the drede of the parelles and dangers of rokkes sandys and grete tempestys be than passid chaungid and turned in saftee and rest.
[tr. Worcester/Worcester/Scrope (1481)]

Therefore, young men, in mine opinion, seem so to die as when a raging and violent flame of fire is quenched, with a great quantity or effusion of water; but old men die as if it were fire, which, lacking wood and cumbustible matter to nourish it, goeth out quietly and is quenched, as though it were of his own accord, not forcibly. And as apples which are green and unripe are not plucked from the tree but by a certain violent plucking, but if they be ripe and mellow they fall voluntarily down from teh tree; so likewise, young men depart out of their life by violent force and painful struggling, but old men die by a certain ripeness and maturity. And as often as I think thereon, I am rapt with such joy and comfort, that the nearer I draw and approach to death, the sooner, methink, I see the dry land, and (as it were, afer a long navigation and seafaring voyage) shall at length arrive at the quiet haven ahd port of all rest and security.
[tr. Newton (1569)]

Therefore a young man seemeth to me to die like fire put out with water, but old men like fire which being put out by no force, is quietly consumed of it selfe; and as apples on trees being not ripe, are plucked of by violence, but being ripe they fall of themselves: so force taketh away the life of young men, but ripenesse of age the life of old men: which consideration is so pleasant to me, that I seem to behold the earth, as a quiet port, whither after a long and troublesome navigation I shall arrive.
[tr. Austin (1648), ch. 21]

All things which Nature did ordain, are good,
And so must be receiv'd, and understood,
Age, like ripe Apples, on earth's bosom drops,
Whil'st force our youth, like fruits untimely crops;
The sparkling flame of our warm blood expires,
As when huge streams are pour'd on raging fires,
But age unforc'd falls by her own consent,
As Coals to ashes, when the Spirit's spent;
Therefore to death I with such joy resort,
As Seamen from a Tempest to their Port.
[tr. Denham (1669)]

For this Reason, I think it not so improper, to compare the Death of Youth to Flames extinguished, by a violent and suddain Splash of Water; and that of Riper Years, to such a Fire, as without any Violence, goes out, when all its Fewel is decayed and spent. And as Fruit, when it is green, is torn and plucked with Violence from the Boughs, which, when become more ripe and mellow, falls gently of it self: so Youth departs this Life with Violent Strugles, while Old Age drops off mature with Years. And indeed the Prospect of this is so far from being unpleasant, that the nearer it is, the more delightful does it seem: nor is it less grateful, than the Sight of land can be to one, quite tired with a long and tedious Voyage.
[tr. Hemming (1716)]

Thus the Youthful seem, I think, to die like Fire forcibly quench'd with Water, whereas the Aged go smoothly off, and like the Fire burnt to the last Spark, need no Force to be extinguished; or as green Fruit which must be plucked from the Trees, but when ripe falls off it self. Thus do the Young die with Repugnancy, and the Old fall with Maturity. So that Life becomes the pleasanter to me, the nearer I approach its End, thinking to myself the Earth is my Harbour, into which I shall arrive, after a long and tedious Voyage.
[tr. J. D. (1744)]

For Young Men seem to be forced from Life, as Fires are extinguished by great Quantities of Water thrown on them; when on the contrary, Old Men expire of themselves, like a Flame when all its Fuel is spent. And as unripe Fruit requires some Force to part it from its native Bough; but when come to full Maturity, it drops of itself, without any Hand to touch it: So Young People die by something violent or unnatural; but the Old by mere Ripeness. The Thoughts of which to me are now become so agreeable, that the nearer I draw to my End, it seems like discovering the Land at Sea, that, after the Tossings of a tedious and stormy Voyage, will yield me a safe and quiet Harbour.
[tr. Logan (1744)]

In the latter instance [youth]; the privation of life may be resembled to a fire forcibly extinguished by a deluge of water; in the former [an old man], to a fire spontaneously and gradually going out from a total consumption of its fuel. Or, to have recourse to another illustration; as fruit before it is ripe cannot, without some degree of force, be separated from the stalk, but drops of itself when perfectly mature; so the disunion of the soul and body is effected in the young by dint of violence, but is wrought in the old by a mere fullness and completion of years. This ripeness for death I perceive in myself with much satisfaction; and I look forward to my dissolution as to a secure haven, where I shall at length find a happy repose from the fatigues of a long voyage.
[tr. Melmoth (1773)]

Therefore young men seem to me to die just as when the force of flame is suddenly overpowered by a mass of water; but old men, just as fire that is spent is extinguished of itself, no violence having been applied to it. And, as apples are pulled from trees by force, if they are unripe; if ripe and mellowed, they fall down; so force takes away life from young men, maturity from old men; which maturity to me, indeed, is so pleasant, that the nearer I approach to death, I seem, as it were, to behold land, and to be about to come, at length, into port form a long voyage.
[Cornish Bros. ed. (1847)]

And thus it is that young men seem to me to die, just as when the violence of flame is extinguished by a flood of water; whereas old men die, as the exhausted fire goes out, spontaneously, without the exertion of any force: and as fruits when they are green are plucked by force from the trees, but when ripe and mellow drop off, so violence takes away their lives from youths, maturity from old men; a state which to me indeed is so delightful, that the nearer I approach to death, I seem as it were to be getting sight of land, and at length, after a long voyage, to be just coming into harbour.
[tr. Edmonds (1874)]

Thus young men seem to me to die as when a fierce flame is extinguished by a stream of water; while old men die as when a spent fire goes out of its own accord, without force employed to quench it. Or, as apples, if unripe, are violently wrenched from the tree, while, mature and ripened, they fall, so force takes life from the young, maturity from the old; and this ripeness of old age is to me so pleasant, that, in proportion as I draw near to death, I seem to see land, and after a long voyage to be on the point of entering the harbor.
[tr. Peabody (1884)]

Accordingly, the death of young men seems to me like putting out a great fire with a deluge of water; but old men die like a fire going out because it has burnt down of its own nature without artificial means. Again, just as apples when unripe are torn from trees, but when ripe and mellow drop down, so it is violence that takes life from young men, ripeness from old. This ripeness is so delightful to me, that, as I approach nearer to death, I seem as it were to be sighting land, and to be coming to port at last after a long voyage.
[tr. Shuckburgh (1895)]

The death of the young seems to me to resemble the sudden extinction of a flame with volumes of water; the old seem rather to die as a fire which flickers out of itself.
[ed. Harbottle (1906)]

To them it comes
It seems to me, as when a fire is quenched
By streams of water: to the old it comes
As when a fire dies slowly down itself:
Just so the apples, when unripe, are torn
With violence from the boughs: if ripe with age
They gently fall: and so the life of youth
Is taken by some violent attack;
The old man's troublous age comes gently to an end.
To me this seems so pleasant, that I feel
The nearer that I draw towards the end,
I sight the land, and see before my eyes
The harbour waiting to receive the bark
Which long as voyaged on the toilsome sea.
[tr. Allison (1916)]

It seems to me that the death of a young man is like the drowning of a blazing flame by a flood of water, whereas the death of the old is like the gradual, utterly gentle and spontaneous flickering out of a fire that has used up its fuel. Fruits, too, if they are green, must be forcefully pulled from the bough, but if they are ripe and mellow, they drop off. So it is with the life of man: from the young, it is taken by violence, from the old, by the fullness of time. This is a thought that gives me great comfort; as I come closer and closer to death, I seem, so to speak, to see the land and to be at last about to come into harbor after a long sea-journey.
[tr. Copley (1967)]

Death at an early age seems to me like a fire that has suddenly been swamped by a bucket of water; but death in old age is like a fire that has not been extinguished but has gone out of its own accord, because it has used up all its fuel. When an apple is not yet ripe, it takes some work to tug it off the branch; but when it is fully ripe, it simply falls to the ground. In the same way, though some act of violence may snatch life from the young, the old are ready to die. And that to me is a pleasant thought -- so much so that the nearer I get to death, the more I feel like a sailor who, after a long voyage, has made landfall and is about to tie up in his home port.
[tr. Cobbold (2012)]

When a young person dies, it seems to me to be like a vigorous flame being put out by a fire hose; with old people, on the other hand, the flame is extinguished, having burned itself out on its own accord with no violent outside force. When unripe apples are plucked from trees it takes real force, but the mature and mellow ones fall gently and naturally. Violence carries life away from the young, from the old it is ripeness. And, you know, the ripeness is so pleasant to me that the nearer I approach death, the more I see it as land and that at last I am about to come into port after a long voyage.
[tr. Gerberding (2014)]

Therefore young people, it seems to me, pass
Away like tall flames put out by a large mass
Of water while old men die out like the fumes
Of an unquenchable fire which consumes
Itself without recourse to another force.
And just as unripe fruits are hard to pluck
From the trees to which they’re closely stuck,
But once mature and fully grown
Drop down to the ground on their own,
So young lives are cut down by ferocity
While old ones are spent by maturity.
A maturity to me so suave
The nearer I get to the grave.
It also seems to me as though
I were almost shouting land-ho!
On reaching the port of destination
After a very long navigation.
[tr. Bozzi (2015)]

A young person dying reminds me of a fire extinguished by a deluge. But when an old person dies, it is like a flame that diminishes gradually and flickers away of its own accord with no force applied after its fuel has been used up. In the same way, green apples are hard to pick from a tree, but when ripe and ready they fall to the ground by themselves. So death comes to the young with force, but to the old when the time is right. To me there is great comfort in this idea, so that as death grows nearer, the more I feel like a traveler who at last sees the land of his home port after a long voyage.
