I've inquired about the differences between a "tinagtagu" and a "galgalawaen" but I've received opposing and sometimes contradicting information. So there's need for more inquiries.
This specific artifact which is tagged as a "tinagtagu" is in the collection of the Linden Museum in Stuttgart, Germany.
The accompanying notes for the artifact which are available in the museum's website state that the item originated from Bontoc, Mountain Province and that it was sold to the museum in the 1970s by a German journalist and antiques trader/dealer named Christian Roll.
Some people have suggested that the artifact could be a "bulul" carved and originated in Ifugao and made its way to Bontoc before it got into the hands of the antiques collector.
I tried researching more about the uses and purposes of the "tinagtagu" (or "galgalawaen") but there's very little information out there. So if there's anyone out there who can point me to papers, resources, or anything that can shed more light about this artifact, feel free to send a message.
