The early English in Sleswick and Friesland had partially reached the agricultural stage of civilisation. They tilled little plots of ground in the forest; but they depended more largely for subsistence upon their cattle, and they were also hunters and trappers in the great belts of woodland or marsh which everywhere surrounded their isolated villages. They were acquainted with the use of bronze from the first period of their settlement in Europe, and some of the battle-axes or shields which they manufactured from this metal were beautifully chased with exquisite decorative patterns, equalling in taste the ornamental designs still employed by the Polynesian islanders. Such weapons, however, were doubtless intended for the use of the chieftains only, and were probably employed as insignia of rank alone. They are still discovered in the barrows which cover the remains of the early chieftains; though it is possible that they may really belong to the monuments of a yet earlier race. But iron was certainly employed by the English, at least, from about the first century of the Christian era, and its use was perhaps introduced into the marshlands of Sleswick by the Germanic conquerors of the north. Even at this early date, abundant proof exists of mercantile intercourse with the Roman world (probably through Pannonia), whereby the alien culture of the south was already engrafted in part upon the low civilisation of the native English. Amber was then exported from the Baltic, while gold, silver, and glass beads were given in return. Roman coins are discovered in Low German tombs of the first five centuries in Sleswick, Holstein, Friesland, and the Isles; and Roman patterns are imitated in the iron weapons and utensils of the same period. Gold byzants of the fifth century prove an intercourse with Constantinople at the exact date of the colonisation of Britain. From the very earliest moment when we catch a glimpse of its nature, the home-grown English culture had already begun to be modified by the superior arts of Rome. Even the alphabet was known and used in its Runic form, though the absence of writing materials caused its employment to be restricted to inscriptions on wooden tablets, on rude stone monuments, or on utensils of metal-work. A golden drinking-horn found in Sleswick, and engraved with the maker's name, referred to the middle of the fourth century, contains the earliest known specimen of the English language.
