Patriartichal blessings

I’ve decided that my patriarchal blessing must not be true, since nearly everyone i’ve heard testify of the truth of theirs has called it a patriartichal blessing. Apparently they all got the true one, and i’m left with a poor imitation.

(Semi-seriously, what is a patriartich, anyway? Maybe it’s actually patriarctic, meaning that they’re from snowy regions? Or maybe it’s a sort of a compound word, patri-article? Where in the world does that pronunciation come from?)
