what does the symbol on spartan shields mean
Spartan army The letter lambda (Λ), standing for Laconia or Lacedaemon, which was painted on the Spartans' shields, was first adopted in the 420s BC, and quickly became a widely known Spartan symbol.[39] Military families passed on their shields to each generation as family heirlooms. The technical evolution and design of Spartan shields evolved from bashing and shield wall tactics, and were of such great importance in the Spartan army that while losing a sword and a spear was an exception, to lose a shield was a sign of disgrace. Not only does it protect the user, but it also protects the whole phalanx formation. To come home without the shield was the mark of a deserter; rhipsaspia or "dropping the shield", was a synonym for desertion in the field. Mothers bidding farewell to their sons would encourage them to come back with their shields, often saying goodbyes like "Son, either with this or on this" (Ἢ τὰν ἢ ἐπὶ τᾶς).[40][41]
Superman logo In modern-day Superman stories published by DC, the symbol is typically explained as being Superman's family crest from his home planet Krypton, known as the insignia of the House of El; the "El" in Kryptonian language translates as "hope", with its resemblance to Latin script letter S being merely a coincidence.
