Big Jim Larkin and William Martin Murphy. Arthur Scargill and Maggie Thatcher. And now Donal Og Cusack and Frank Murphy. Another fine pair of strikers.
You can't have a proper strike without 'em. Two intractably opposed, obdurately resolute foes; but, really, two peas in a pod. While they sit in their war rooms, plotting their next move, devising the next advance on the No Man's Land of public opinion, they dream of routing their enemy utterly.
But, really, their impulses must be the same. The stubborness, the sense of moral superiority, the ownership of a poker face, and, undoubtedly, the colossal ego required to carry it all, to lead men beyond where they're not sure they want to go.
Because of the similiarities, ultimately, there is mutual respect. Apparently, in squad trips and holidays since they first crossed swords in the 2002 strike, Cusack and Murphy have maintained the utmost civility - "morning Frank", "morning Donal, and a fine day it is too", "it is that Frank, no doubt about it."
The charismatic figurehead is a sine qua non of a strike. The ability to organise a group of disparate individuals into one, unified voice in any circumstance is difficult; to do so while also persuading them to withdraw their services from a hitherto rewarding position is perhaps the ultimate manifestation of great leadership.
Of course, the fact that GAA players are not waiving a salary means they cannot truly be compared with those who strike in the industrial realm. But to be a Cork player over recent months, when many - the majority, by all accounts - of the public do not agree with your stance must have been a frequently buffeted station, with only one's principles to provide shelter.
If there has been a slight veering of opinion towards the players' side in recent weeks, perhaps it has been in recognition of the resoluteness of their stance. No player has broken ranks, no off-the-record "sources" have told of splits within the panels, though I'm sure many have been solicited to do so.
As well as this, the media pincer movement orchestrated by Cusack last week was bold and risky. But if strikes are won in the realm of public opinion, you must make sure to take the high ground. Could any Cork board member be as articulate and heartfelt in his case as Seán Og O hAilpín? It was a masterstroke to put one of Irish sport's most loved personalities forward so.
Whether O hAilpín's call for Frank Murphy's head was indiscretion on his part, or a calculated gambit from the Cusack's masterplan, will all come out in the wash eventually. By then we'll know if Cusack has succeeded where Big Jim and Scargill failed.
