You grant your favours, Caelia, to Parthians, to Germans, to Dacians;
and despise not the homage of Cilicians and Cappadocians.
To you journeys the Egyptian gallant from the city of Alexandria,
and the swarthy Indian from the waters of the Eastern Ocean;
nor do you shun the embraces of circumcised Jews;
nor does the Alan, on his Sarmatic steed, pass by you.
How comes it that, though a Roman girl,
no attention on the part of a Roman citizen is agreeable to you?

[Das Parthis, das Germanis, das, Caelia, Dacis,
nec Cilicum spernis Cappadocumque toros;
et tibi de Pharia Memphiticus urbe fututor
navigat, a rubris et niger Indus aquis;
nec recutitorum fugis inguina Iudaeorum,
nec te Sarmatico transit Alanus equo.
qua ratione facis cum sis Romans puella,
quod Romana tibi mentula nulla placet?]

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

(Source (Latin)). Other translations:

For Parthians, Germans thou thy nets wilt spread;
Wilt Cappadocian or Cilician wed;
From Memphis comes a whipster unto thee,
And a black Indian from the Red Sea;
Nor dost thou fly the circumcised Jew;
Nor can the Muscovite once pass by you;
Why being a Roman lass dost do thus? tell
Is't cause no Roman knack can please so well?
[tr. Fletcher]

You grant your favours to Parthians, you grant them to Germans, you grant them, Caelia, to Dacians, and you do not spurn the couch of Cilicians and Cappadocians; and for you from his Egyptian city comes sailing the gallant of Memphis, and the black Indian from the Red Sea; nor do you shun the lecheries of circumcised Jews, and the Alan on his Sarmatian steed does not pass you by. What is your reason that, although you are a Roman girl, no Roman lewdness has attraction for you?
[tr. Ker (1919)]

Caelia, you love a Teuton swain,
An Asiatic stirs your pity,
For you swart Indians cross the main,
Copts flock to you from Pharos' city.
A Jew, a Scythian cavalier,
Can please you -- but I can't discover
Why you, a Roman, are austere
To none except a Roman lover.
[tr. Pott & Wright (1921)]

You give your favors to Parthians, you given them to Germans, Caelia, you give them to Dacians, nor do you despise the beds of Cilicians and Cappadocians; and to you comes sailing the fornicator of Memphis from his Pharian city and the black Indian from the Red Sea. Nor do you shun the loins of circumcised Jews nor does the Alan pass you by with his Sarmatian horse. Why is it, sinc eyou are a Roman girl, that no Roman cock is to your liking?
[tr. Shackleton Bailey (1993)]

You do Germans, and Parthians, and Dacians, Caelia,
you don’t scorn Cappadocian, Cilician beds;
and fuckers from Memphis, that Pharian city,
and Red Sea’s black Indians sail towards you.
You’d not flee the thighs of a circumcised Jew,
not an Alan goes by, with Sarmatian horse too.
What’s the reason, then, since you are a Roman,
not one Roman member pleases you, woman?
[tr. Kline (2006), "Hard to Please"]

Barbarian hordes en masse you fuck,
Odd types into your bed you tuck.
You take on blacks and Asian forces,
And Jews, and soldiers, and their horses.
Yet you, voracious Roman chick,
Have never known a Roman dick.
[tr. Wills (2008)]

You sleep with Germans, Parthians, and Dacians;
Cilicians and Cappadocians get a screw;
a Memphian fucker sails to you from Pharos;
a coal-black Indian from the Red Sea, too.
You don't shun the pricks of circumcised Judeans;
a Scythian on his horse won't pass you buy.
Since you're a roman girl, why is it, Caelia,
you won't give any Roman cock a try?
[tr. McLean (2014)]

You grant your favours, Caelia, to all races --
Parthians, Germans, Dacians share your graces.
Cilicians, Cappadocians in your bed be,
And even a swarthy Indian from the Red Sea!
From Egypt's Memphis one sails to your door,
And Jews, though circumcised, you'll not ignore,
And that's not all! On his Samartian steed
No Scythian ever passed your door at speed.
You are a Roman girl, so tell me true,
Do Roman weapons have no charms for you?
[tr. Pitt-Kethley]

You'll fuck a Frog, a Kraut, a Jew,
A Gippo, a Brit, a Pakki too;
Niggers and Russkies all go in your stew
But my prick's a Wop -- Caelia, fuck you!
[tr. Sullivan]
