Hephaestus

Necessity inspires industry and there would still be Iron. Surviving societies would have the advantage of a lost civilization's wasted world turned into easily accessible scrap and charcoal. Unlike the ancient Greeks, new beginnings for humans would bypass the Bronze Age. It would be an age of iron.

Leather and wool, however, would be a short commodity. Both wild and domestic animals would survive in very few numbers because most would have been eaten generations before. The same holds true for most all natural textiles. Cotton and flax take great expanses of irrigated land and what limited agriculture remained would be desperately needed for food production.

Painting based in part on the Greek myth, “Hephaestus”.

Hephaestus was the Greek god of technology, blacksmiths, craftsmen, artisans, sculptors, metals, metallurgy, fire and volcanoes. Like other mythic smiths but unlike most other gods, Hephaestus was lame, which gave him a grotesque appearance, at least in Greek eyes. Still he served as the blacksmith of the gods, and was worshiped in the manufacturing and industrial centers of Greece, particularly in Athens.
