Also, I'd posit that Worcestershire sauce is the spiritual descendant of garum.
Last time I was in Thailand I delved into foods made with tai pla. It's a sauce that is thicker and made from fish entrails. Based on descriptions of garum I've read, this seems to be very close.
It's tough to accurately describe taste and flavor in literature.
