Question

how was sheep useful in early time

Answer 1

HEY MATE....

Life without sheep was unthinkable. For the average Anglo-Saxon, sheep meant sustaining meat, milk, and cheese, healing wool-wax, valuable parchment, and most vitally, fleece. Fleece to be shorn or pulled, and spun and woven into cloth. Recall that there were then only two types of fabrics: woolen ones, and linen. (Only the very rich, on rare, ceremonial occasions, clothed themselves in imported silks.)
