Too small? Idk if it's too broad of an answer but that's what I've been told
It was a trigger that showed that there were two competing powers in Europe: Russia and Austria-Hungary (and their allies).
Franz Ferdinand was killed by a Serbian separatist and the Austrians wanted him to be punished. On the other hand, Russia supported Serbia is saying that Austrian demands ( to be allowed to search for the culprit inside Serbia) were too much.
This lead to a direct conflict between the two powers (Austria and Russia) and further lead to the war.
It's Odysseus and not Ulysses if this is Greek mythology (hence Zeus). That Greek God is Hermes, or Mercury if in Roman mythology (hence ulysses). Use Mercury or Hermes depending if it's Roman or Greek mythology. Determine which one is which as your question mixes the mythologies up.
