More old buckles to ID if you can

[TORRERO]

This was dug in a field that yielded hundreds of artifacts from Roman times to 1900's
Don't know its purpose but was told it was a sash or sword strap buckle.
One of the biggest we ever dug there.
any help would be great.

Whoa, nice!

Here's a couple, 1500-1650 and 1630-1690.

The spectacle buckle has one of the longest timeframes. Started in the late medieval (16th C maybe a little earlier) until the early 18th C. The larger type like this are generally later & yours is probably mid 17th C. They were used on everything, purses, belts, horses etc.. Yours is probably a sword belt type but nearly impossible to guess.
