I finished Deepwater Horizon: a Systems Analysis of the Macondo Disaster by our very own Earl Boebert.
Now I am reading Engineering in the Ancient World by J.G. Landels, which I found in the discards pile at the library. There's a chapter on Greek and Roman ship construction, which is all new to me. I knew a little bit about clinker-built ships, but it turns out the Mediterranean type people did it completely differently.
Odysseus has been detained on an island by the beautiful nymph Calypso for a number of years. When is at last allowed to leave she does not conjure up a boat by magic or produce one which she had kept hidden. Instead, she presents Odysseus with a set of tools and shows him where to find suitable timber on her island. Odysseus turns out to be not merely the warrior hero of epic tradition, but also a skilled and knowledgeable craftsman. Homer clearly assumed that his audience knew about, and were interested in, the details of shipbuilding and equipment.
No wonder Penelope didn't give up on him.
