In fact as long as mythology is concerened you shouldnt use greek mithology to compare with other native european mithologies because it is heavily influenced by semitic and other middle eastern myths. Despite interpretatio graeca being the common framework for a long time. If anything classical greek mithology is more middle eastern than persian mythology.

One may claim that legaly european civil law originates from the bizantine theodosian code. But it is a medieval inovation. both the code and the way it was aplied bear little to either greek or roman legal and administrative traditions. Wich again are more similar to middle eastern traditions like islamic law. In fact in the few cases were ancient roman forms have been preserved like in the spanish fueros it is because of arabic influence. Other than that european legal tradition including democratic ideas is much more heavily influenced by salic law than by grecoroman forms.
