Like the Athenian miser, who was wont
To meet men’s curses with a hero’s front:
“Folks hiss me,” said he, “but myself I clap
When I tell o’er my treasures on my lap.”

[Ut quidam memoratur Athenis
sordidus ac dives, populi contemnere voces
sic solitus: ‘populus me sibilat, at mihi plaudo
ipse domi, simul ac nummos contemplor in arca.’]

Horace (65-8 BC) Roman poet, satirist, soldier, politician [Quintus Horatius Flaccus]

Satires [Saturae, Sermones], Book 1, # 1, “Qui fit, Maecenas,” l. 64ff (1.1.64-67) (35 BC) [tr. Conington (1874)]

Such one we reade of in olde tyme, that dwelte in Athins towne,
A man in substance passinge rytche, nathlesse a niggerde cloune,
At whose scarceheade, and covetyce the worlde did outas make,
But all in vayne, he forste it not, he sought not howe to slake
Blacke fame, that frisked everye wheare, and bounsed at ytche eare,
"A figge for them (brasen face) I force not howe I heare,
"They hauke, they hem, they hisse at me, I weygh it not an hawe,
"Whilste I may harbor in mine arke, and lodge wythin my lawe
"My darlynge goulde, my leaves gueste, my solace and my glee,
"He is the bone companion, its he that cheares up me."
[tr. Drant (1567)]

Thus that Athenian Monster Timon, which
Hated Man-kind, a sordid Knave, but rich,
Was wont to say, When ere I walk abroad
The People hiss me, but I do applaud
And hug my self at home, when I behold
My chests brim-full with Silver and with Gold.
[tr. A. B.; ed. Brome (1666)]

Since He, as the Athenian Chuff, will cry
The People hiss me, True, but what care I?
Let the poor fools hiss me where e're I come,
I bless my self to see my bags at home.
[tr. Creech (1684)]

At Athens liv'd a wight, in days of yore,
Though miserably rich, yet fond of more,
But of intrepid spirit to despise
The abusive crowd. "Let them hiss on," he cries,
" While, in my own opinion fully blest,
I count my money, and enjoy my chest."
[tr. Francis (1747)]

Self-cursed as that same miser must have been,
Who lived at Athens, rich as he was mean, --
Who, when the people hiss'd, would turn about
And drily thus accost the rabble-rout:
"Hiss on; I heed you not, ye saucy wags,
While self-applauses greet me o'er my bags."
[tr. Howes (1845)]

As a certain person is recorded [to have lived] at Athens, covetous and rich, who was wont to despise the talk of the people in this manner: “The crowd hiss me; but I applaud myself at home, as soon as I contemplate my money in my chest.”
[tr. Smart/Buckley (1853)]

As wretched as, at Athens, some rich miser was, who (as they say) was wont to thus despise what people said of him: "Aha ! the Public hiss, but in my heart I say I m right, directly that I gaze upon the coins in my strong-box."
[tr. Millington (1870)]

He is like a rich miser in Athens who, they say, used thus to scorn the people's talk: "The people hiss me, but at home I clap my hands for myself, once I gaze on the moneys in my chest."
[tr. Fairclough (Loeb) (1926)]

Like the man they tell of
In Athens, filthy but rich, who despised the voice
Of the people and kept saying, "So! The citizens hiss at me!
Ah! But I applaud myself alone at home
When I gaze on the coins in my strongbox."
[tr. Palmer Bovie (1959)]

They're like an Athenian I heard about
Rich and stingy, he thought nothing of the people's snide remarks,
and always said, "They hiss me, but I applaud myself
at home, as soon as I lay eyes on the money in my chest."
[tr. Fuchs (1977)]

As the Athenian miser
Is said to have answered, when citizens
Mocked him: "They hiss me, but at home I
Applaud myself, counting the coins in my safe."
[tr. Raffel (1983)]

Like that one
about whom the story was told in Athens:
stingy and rich, he used to express
his scorn of the people’s jibes with these words:
"The people may hiss me, but at home
I applaud myself as I contemplate
my gold in the strongbox."
[tr. Alexander (1999)]

He’s like the miser in Athens
who scorned, it’s said, what people thought of him.
“They hiss me in the streets, but once I’m home
I stare at my bright coffers and applaud
myself.”
[tr. Matthews (2002)]

He's like the rich
Athenian miser who treated the people's remarks with contempt.
"The people hiss me," he would say, "but I applaud myself
when I reach home and set eyes on all the cash in my box!"
[tr. Rudd (2005 ed.)]

Like the rich Athenian miser
Who used to hold the voice of the crowd in contempt:
"They hiss at me, that crew, but once I’m home I applaud
Myself, as I contemplate all the riches in my chests."
[tr. Kline (2015)]
