Pietro Pecco's video: Spartan helmets @ Delphi Greece

The Corinthian helmet was born in ancient Greece and takes its name from the polis of Corinth. It was a type of bronze helmet which in its later form covered the entire head and neck, with slits for the eyes and mouth. The Corinthian helmet was the type of Greek helmet that offered the best protection in battle for the head but this at the price of significantly impeding the sight and hearing of the hoplite who wore it. In times of peace, therefore, the Greek warrior wore the Corinthian helmet turned back on the neck (like the goddess Athena in many depictions or like Pericles). This habit led to a series of variations in Italy, where the slots were almost closed, given that the helmet was no longer lowered over the face but worn as a headgear. Entirely made from a single piece of metal (bronze), the Corinthian helmet consisted of a tile stretched out to fully cover the forehead, with a long nasal on the tip of which converged protuberances lanceolate para-cheeks as long as the chin. A large curved projection protected the nape, similar to the Roman galley and the morion of the conquistadors or the German Stahlhelm. According to artistic and archaeological evidence, the Corinthian helmet was the most common type of kranos among the heavy infantry forces of archaic Greece and the first phase of classical Greece. It subsequently fell into disuse in favor of more "open" types of helmet: fond. Chalcidian helmet and Phrygian helmet. In ancient Rome it was introduced either by the Etruscans or by the peoples of Magna Graecia but, due to its very high cost, it was used only by the wealthiest Roman citizens. Although the classical Corinthian helmet fell out of use with the Greeks, the Italo-Corinthian types remained in use until the 1st century AD, being used by, among others, the Roman army. The Venetian Fanti da Mar owned it until the 14th century and it remained, but only as a gift, with elaborate finishes to embassies or high-ranking people until the end of the republic.
