Lost
A 1,500-year-old Maya stone box that had been looted from a Guatemalan cave has been returned by an unnamed collector.
The artifact was delivered anonymously to officials at Guatemala's Ministry of Culture last week.
Experts had described the artifact as one of the most impressive finds from the Early Classic Period (A.D. 250-600) of ancient Maya civilization.
The vessel's theft, first noticed two months ago, led Guatemalan authorities to launch a national investigation.
