While rivers run into the deep,
While shadows o’er the hillside sweep,
While stars in heaven’s fair pasture graze,
Shall live your honour, name, and praise,
Whate’er my destined home.

[In freta dum fluvii current, dum montibus umbrae
lustrabunt convexa, polus dum sidera pascet,
semper honos nomenque tuum laudesque manebunt,
quae me cumque vocant terrae.]

Whilst convex'd hills have shadows, to the maine,
Whilst rivers run, whilst poles the stars sustaine,
Thy honour; name, and same, shall last, what land
So-ever me invites.
[tr. Ogilby (1649)]

While rolling rivers into seas shall run,
And round the space of heav'n the radiant sun;
While trees the mountain tops with shades supply,
Your honour, name, and praise shall never die.
Whate'er abode my fortune has assign'd,
Your image shall be present in my mind
[tr. Dryden (1697)]

While the rivers to the sea
Shall run, -- while mountain shadows move around
Their sides, -- and while the heavens shall feed the
stars. So long thy honor, and thy name and praise
Shall last, whatever lands may call me hence.
[tr. Cranch (1872)]

While rivers run into the sea, while the mountain shadows move across their slopes, while the stars have pasturage in heaven, ever shall thine honour, thy name and praises endure in the unknown lands that summon me.
[tr. Mackail (1885)]

Now while the rivers seaward run, and while the shadows stray
O'er hollow hills, and while the pole the stars is pasturing wide,
Still shall thine honour and thy name, still shall thy praise abide
What land soever calleth me.
[tr. Morris (1900)]

O, while the rivers run
to mingle with the sea, while shadows pass
along yon rounded hills from vale to vale,
and while from heaven's unextinguished fire
the stars be fed -- so long thy glorious name,
thy place illustrious and thy virtue's praise,
abide undimmed. -- Yet I myself must go
to lands I know not where.
[tr. Williams (1910)]

While rivers run into the sea, while on the mountains shadows move over the slopes, while heaven feeds the stars, ever shall thy honour, thy name, and thy praises endure, whatever be the lands that summon me!

While rivers run to sea, while shadows move
Over the mountains, while the stars burn on,
Always, your praise, your honor, and your name,
Whatever land I go to, will endure.
[tr. Humphries (1951)]

So long as rivers run to the sea, and shadows wheel round
The hollows of the hills, and star-flocks browse in the sky,
Your name, your fame, your glory shall perish not from the land
Wherever I am summoned to go.
[tr. Day-Lewis (1952)]

While rivers run into the sea and shadows
still sweep the mountain slopes and stars still pasture
upon the sky, your name and praise and honor
shall last, whatever be the lands that call me.
[tr. Mandelbaum (1971), l. 852ff]

So long as brooks flow seaward, and the shadows
Play over the moutnain slopes, and highest heaven
Feeds the stars, your name and your distinction
Go with me, whatever lands may call me.

while the sky nourishes the stars.

Move over mountainsides, while the sky
Pastures the stars, ever shall your honor,
Your name, and your praises endure,
Whatever the lands that summon me.

whatever lands may call me to their shores
