Hi everyone
Robt
Have a look on plate 14 c of the same book. A burly design kemuning could also be nice but usually it's more like 10 a or 11 a.
And Guess who came for dinner last night... I found a cousin of your Hulu
It is not a Hulu but there are many similarities like, sex, wings, crest, bulging eyes...
It comes from L'art populaire à Bali of Urs Ramseyer. I think they just republished it in a new version (english). Urs describe this little guy (plate 230) as "Caratan Cicipan" a devil bird spreading his wings and ornamenting a
holy water container. The water goes through out of the penis. Terra cota from Djasi, Karangasem 14.5cm diameter and 27 cm high from the museum of Bali MB 222
It is used in ceremony of purification before mabhakti (veneration).
Hope it leads somewhere...
