Translation:The French Revolution is historic.
Does Greek make the distinction we have in English between "historic" and "historical"? As far as I can tell it does not:
historic adj (relating to history) (σχετικός με την ιστορία) ιστορικός επίθ Historic accounts of the river all mention its earlier course.
historic adj (event: important in history) (γεγονός σημαντικό στην ιστορία) ιστορικός επίθ The pope's visit to the tiny village was historic.
Greek uses "ιστορικός" for both meanings.
In your definitions above...which btw were also mentioned in another comment on this page ... you used "historic" for both examples. You may want to change one of them . ;)
