Alex Poulos posted a Greek paleography tutorial with examples taken from Bayerische Staatsbibliothek, Cod. graec. 314 (Origen, Homilies on the Psalms). The tutorial “[i]s targeted at people who have at least an intermediate knowledge of Greek, but haven’t done much paleography themselves (ie, they haven’t read from manuscripts) … it will allow one to take part in excitement of the new discovery.” SEE THE TUTORIAL HERE.
