5865069 Sword, late second or very early third century (iron) by Roman; length: 46 cm; Arbeia Roman Fort & Museum, Tyne & Wear Archives & Museums; (add.info.: The blade is an early example of \'pattern-welding\', when small iron bars are twisted together to make a pattern in the metal, although the double herring-bone pattern is now only visible under X-ray. It has also been inlaid with an eagle between military standards and a figure of Mars, the god of war. This would have been a very expensive sword, and seems to have been given as an offering to the gods); Tyne & Wear Archives & Museums.
