Dual Swords

[pogoman]

Hi,

I'm pretty new to the forums here, but I've always been fascinated by all kinds of swords and swordplay. I was wondering if anyone here knew of any culture or time period during which some sort of dual-sword fighting was used? I ask simply because I can't find any resource on the subject anywhere, and while I'm quite aware that it's a pretty uncommon style of fighting there must be someone, SOMERWHERE who used it.

Thanks!
