Small tidbit that I found interesting:

Finally, the urn in L-8 not only contained bone remains and a gold ring carved with Jano Bifronte, but it was also filled to the brim with a reddish liquid.

That ring was likely something that the deceased wore in life, either as an ornament or to show their “role” in society. Still, the fact that a funeral item was carved with Janus - the god of the beginnings and ends - seems fitting.
