I ran across this quote by Picasso himself that I think may help clarify what RAZD is getting at
quote:
Art is a lie that makes you realize the truth. - Picasso
It could be said that since these myths are "lies", there is no truth in them. I think RAZD is using Guernica to suggest or illustrate the point that even though these stories may not be "true" they can point a person to the truth or help them realize the truth.

Whoever calls me ignorant shares my own opinion. Sorrowfully and tacitly I recognize my ignorance, when I consider how much I lack of what my mind in its craving for knowledge is sighing for. But until the end of the present exile has come and terminated this our imperfection by which "we know in part," I console myself with the consideration that this belongs to our common nature. - Francesco Petrarca
"Nothing is easier than to persuade people who want to be persuaded and already believe." - another Petrarca gem.
