The "barb" is always the tricky part to make. Some people have good luck with a small sharp chisel to cut them. Never worked for me. I either end up cutting too deep and cutting the end off, or I cut too shallow and peel a little stip off the side.
So when I make fish hooks, I "forge" and then file the barb. I flatten/flair the end, then use a fine triangular file to file in and then undercut that barb. Then I file the point. When I have the point/barb done, I then use scrolling pliers to bend the hook. And then cut to length and flatten/flair the end.
For 900 A.D. Viking style hooks, I do the hook the same way, but curl a small eye on the end. The original is shown in the book The Vikings: the North Atlantic Saga. It was found beneath a waterfall along with a fish spear - 9 inches long with two large "thorn like" barbs and a small socket on the end.
The simplest quick fish hook to make would be to take a large hook with long shaft from the tackle shop. Then cut the eye off, and flatten/flare the end. Run a stone over the end to remove any sharp edges. It fits the time period, and looks right. Some people selling historical fishing kits are including hooks made this way. Yes, they are "forged", but machine forged in large quantities at modern factories - except for that flared end. And if you search the tackle shops and web sites, you can even find new made modern hooks with that flared end instead of an eye.
But not all hooks had that barb. Many didn't. And there are Indian made Copper Culture fish hooks that do not have any barb - just the copper hook. And they have either bulged/flared ends or small eyes on them.
A good book to get if you can find it is:
The Colonial Angler's Manual of Flyfishing & Flytying by Ken Reinard isbn 1-56523-070-1. The first part of the book is his search/research to create the gear George Washington might have used to go fly fishing. The middle part shows his steps to make his pole and make hooks. The last part shows color plates of original fishing flys for the colonial time period - and many are still common.
You can find the book and more info on Paul Jones's web site

He has lots of historical info on it, and also offers some things for sale. Last I heard, he had bought up the last stock of the original printing of the Colonial Angler book. So he might have some copies left.
And he has lots of links to other web sites on historical fishing.
