We may all resort, at the summer solstice, to the warmest spots of Italy, to Ardea, Pestum, and Baiae, fervid with the heat of the constellation Leo, since Curiatus condemned the air of Tivoli, when he was on the point of being transported from its extolled waters to those of the Styx. Fate is not to be diverted by localities: when death comes, the pestilent Sardinia is to be found in the middle of the healthy Tivoli.

[Ardea solstitio Castranaque rura petantur
Quique Cleonaeo sidere fervet ager,
Cum Tiburtinas damnet Curiatius auras
Inter laudatas ad Styga missus aquas.
5Nullo fata loco possis excludere: cum mors
Venerit, in medio Tibure Sardinia est.]

Marcus Valerius Martial
Martial (AD c.39-c.103) Spanish Roman poet, satirist, epigrammatist [Marcus Valerius Martialis]

Sardinia was considered a proverbially unhealthy locale, while Tivoli (Tibur) was considered a healthy resort to travel to during the summer.

(Source (Latin)). Alternate translations:

When Leo rages with the summer's sun,
From pestilential climates never run;
Since, in the wholesom'st and the purest air,
The destinies Croatius did not spare.
When thy time's come, death from no place is bound,
Sardinia in the midst of Tibur's found.
[tr. Killigrew (1695)]

To Ardea, Pestum, roam, and e'er so far;
Or glow beneath the Cleonean star:
While Curiatius damns Tiburtian gales,
As down the healthfull streams to Styx he fails.
The Fates no place debars: if Death be there,
Alike is Tibur's and Sardinia's air.
[tr. Elphinston (1782), 9.10]

Let us in the summer solstice retire to Ardea and the country about Paestum, and to the tract which burns under the Cleonaean constellation; since Curiatius has condemned the air of Tivoli, carried off as he was to the Styx notwithstanding its much-lauded waters. From no place can you shut out fate: when death comes, Sardinia is in the midst of Tivoli itself.
[tr. Bohn's Classical (1859)]

Go where you will, you cannot shut
The door on Fate; when Death draws nigh,
Then far Sardinia is as near
As Tibur.
[ed. Harbottle (1897)]

Seek ye Ardea in summer's heat, and the field sof castum, and teh meads scorched by Cleonae's star, seeing that Curiatius condemns Tibur's air; from amid waters so belauded was he sent to Styx. In no spot canst thou shut out fate; when death comes even in Tibur's midst is a Sardinia.
[tr. Ker (1919)]

Now must we say, if thou be wise
In summer’s heat to Ardea turn,
Or seek the plain where Castrum lies
And the hot stars of Leo burn.
He that is laid in yonder grave
Saith, "Tarry not but get thee gone."
Here sought he Arno’s healing wave,
But found the stream of Acheron?
[tr. Pott & Wright (1921)]

To Ardea and Castrum let us go
In the dog-days when all the heaven's aglow.
Tibur's a death trap; Curiatius died,
Sent mid its breezes to the Stygian tide.
Death ranges at his will; when so inclined
In Tibur's bosom he'll Sardinia find.
[tr. Francis & Tatum (1924), ep. 195]

Now in the blazing heat we might as well escape
to Castrum, or Ardea, or any sunburnt landscape,
since Curiatius has laid a curse
on the air of Tivoli by dying there,
where the waters are also salubrious.
No place can fend off death. It's no worse
to expire in sickly Sardinia than in a spa.
[tr. Bovie (1970)]

At the solstice let us make for Ardea and the Castran countryside and whatever fields are scorched by Cleonae's constellation, since Curiatius damns the breezes of Tibur, dispatched to Styx amid her lauded waters. In no place can you shut out fate; when death comes, in the midst of Tibur is Sardinia.
