How do you salute in Spartan?

Answer 1

There exists a misconception that the Spartan salutation is similar (and thus borrowed by) with the Roman salutation (which is supposedly then borrowed by the Nazis). There is no evidence to support that whatsoever.

The Nazi-like salutation first appeared on the painting "Oath of the Horati" on the 18th century and has nothing to do with Rome, much more with Spartians. There is no knowledge on how the Spartans saluted unfortunattely.
