In the BC period of Greek history, he waged war on a strong foe, the Romans, and had the honour of proclaiming victory against them.
A phenomenal achievement given Rome usually swept all before them.
Much as we would like to believe that the Asterix cartoon stories were real, they were not as the Latin-speakers had a top-notch record on the battlefield.
So for Pyrrhus to rack up a victory or two against the might of Rome was quite some achievement.
Because, believe it or not, every time he won, he weakened his own position and resources, both human and financial, would be drained with each campaign.
Rome, despite these setbacks, could take such defeats on the chin because more soldiers and more money was available to them and they could play the long game of waiting for Pyrrhus to play all his cards knowing full well they would be the ultimate victors.
As Pyrrhus himself once said: "If we are victorious in one more battle with the Romans, we shall be utterly ruined."
If his name sounds familiar then it should.
The phrase 'Pyrrhic Victory' was inspired by Pyrrhus' unfortunate luck and describes a win which is ultimately hollow.
Scottish football right now seems to have a very good example of such a victory on its doorstep.
When Dave King triumphed at the egm at Rangers football club back in March, one young scribe from a Glasgow-based newspaper squealed with excitement on social media site Twitter.
Neither this chap, nor many Rangers fans or Dave King did this.
After all, if your enemy still draws breath and you've not much left to support a defence against a reprisal, a victory booze-up might not be the wisest thing to do.
Hubris can be like a bottle of whisky - good to savour at the time but the hangover can be painful.
And the Alka-Seltzer is needed right now.
A shareholder of Rangers Football Club has called for another egm to be held on June 12.
This particular investor has quite a bit of clout.
He may only hold just under 10 per cent of shares in the club but he has this new company/club (*delete as appropriate if some in light blue are talking about trophies or debts of the institution that Murray broke and Whyte shattered) by the whatsits.
Mike Ashley has the retail revenue and will be paid a packet by the club regardless of how many shirts the shop and Ibrox sells.
He has also been very generous in supplying loans in order to keep this entity running as a going concern.
Five million quid was that arrangement, lest we forget the interest.
King got rid of his people in the last egm and was not very gracious towards Ashley before the event either.
He no doubt thought he could stroll in and run the place without having to pay much attention to someone he thought was just a 'minor shareholder'.
Then he probably looked at the books and the existing contracts and promptly saw his jaw drop down the famous marble staircase at Ibrox.
Because the big revolution hasn't quite happened. The vast millions that King promised he would pump in (his kiddywinkles' inheritance remember) seem to be taking its time coming through the Western Union wire.
Lest we forget the empty promises of 'more transparency' and 'a NOMAD' to represent them on the stock exchange that they would eventually de-list from because the NOMAD was nowhere to be seen.
Surely this had not been one gigantic bluff played out just to satisfy a narcissist's vanity?
Ashley seems to think so and has upped the ante by calling this egm - in particular, to ask for his loan back.
The current board, led by the Springbok King (who can be reached at a luxury South African golf course near you), have recommended that shareholders vote against the proposal to pay back Mr Ashley saying it would be "disadvantageous" for the club/company (*again delete as appropriate depending on which soothsayer you're talking to) to do just that.
You can imagine what your bank manager would say to that when he asks you about your monthly repayment for the car loan not arriving.
Many Rangers fans have campaigned (and with some justification it must be said) for Mike Ashley to get out of their club/company (*think you get the general idea by now).
As has been shown in his running of Newcastle United, making money for himself is all he appears to be bothered about.
A billionaire but is not prepared to invest in players, scouting and youth development despite his deep pockets.
Rich though he may be, this is not the man to have Rangers challenging for the top prizes in Scottish football and ensuring that they can do just that in the long-term.
So, the sooner he's gone the better?
You would think so and given Dave King's boasts of how much loot he was going to inject into Ibrox it would be a piece of cake to pay the man off?
Not only for his loan but to buy out his shares as well - get the monkey off the back so to speak.
Yet this fabulously wealthy Apartheid-rand taker hasn't do so.
Has he been..... fibbing?
King may not have the means to pay him back.
After all, given the numbers he was boasting of before March's egm, £5million would surely be a drop in the ocean for the likes of him?
Instead it would appear to be a bit of a burden for King given his advice to shareholders to vote against paying this loan back.
The blind faith brigade, hoping that their saviour can one day emerge from the protea and save them, will probably support him regardless.
But one or two fans have at long last started to ask questions.
Why would a prime opportunity to get rid of Ashley be delayed by the man who said he would do just that?
The result of this egm will not matter to Ashley one little bit.
The deck of cards is loaded in his favour and he has a number of aces to play.
Win the vote, King has to pay up and pronto.
Lose the vote, then the suits with the briefcases will probably be round pronto to serve King with some documents.
Ones that could see a protracted legal battle take place regarding the club/company (*Ashley is easy on whichever entity settles up) not honouring this loan agreement.
Ashley has the wealth and means to engage in the courts.
He can afford to play a waiting game.
Whether King can do likewise will be another matter.
And like Pyrrhus with the Romans, he may find ultimate victory to be both costly and out of reach.
As Greek historian Plutarch said of Pyrrhus' efforts....
"The armies separated; and, it is said, Pyrrhus replied to one that gave him joy of his victory that 'one other such victory would utterly undo him'. For he had lost a great part of the forces he brought with him, and almost all his particular friends and principal commanders; there were no others there to make recruits, and he found the confederates in Italy backward. On the other hand, as from a fountain continually flowing out of the city, the Roman camp was quickly and plentifully filled up with fresh men, not at all abating in courage for the loss they sustained, but even from their very anger gaining new force and resolution to go on with the war."
Otherwise Ashley will throw him to the lions.
