I have no clue what Greek mythology is exactly but i know it is a cool topic to learn about. you should go to Britannica encyclopedia to find out.

The Greek myths are so old that all we know is that they originated in Ancient Greece. No one knows who invented them, or if they are real, for that matter -- what we call their mythology was their religion (basically).
I can find no references to either the flower, the mineral or the surveying tool in mythology.
Poseidon is a figure from Greek mythology, so you can learn more about him by reading ancient Greek texts like the Iliad and the Odyssey. You can also find information about Poseidon in books about Greek mythology, or by exploring websites dedicated to Greek gods and goddesses.
Yes, you can compare almost any mythology to another. For example I could compare Zeus and Thor. This a chart of what they have in common. -Lightning God -Primary God -Live in a World that is considered better than the human world. (Asgard for Norse and Olympus for Greek) These are a very few and simple things they have in common, if you spent a longer time on it you could come up with many more similarities. You could also find what is different about them.
