I've often read that Padraig Pearse read the Proclamation "from the steps of the GPO." This always bugged me as I've walked past the building many times and there are no steps there. Images from 1916 show the same.
I know it's not important in the grand scheme of things but I thought it might be interesting to start a thread on similar inaccuracies.
Another example is when people quote Marx's statement that religion is "the opium of the people" to give the impression that religion kept people sedated&oppressed. The quote in context reveals a more sympathetic view of religion:
"Religion is the sigh of the oppressed creature, the heart of a heartless world,
and the soul of soulless conditions.
It is the opium of the people."
