Maya whistle

Daniel Courtney writes: ‘I’m the son of a woman who married into a Yucateco family of Mayan descent. 17 years ago I was given a gift by my step father’s mother. It is a small artifact that she found in a sink hole on her property in Yucatan. It is, supposedly, a small figure of the goddess of fertility; it also doubles as a whistle. I would like to know if it is legitimately from the time of the Mayan civilization, older, or a more contemporary piece. When my grandmother gave me this piece I was told never to blow it as it would call the “Alux” (small people) from the jungle to carry the dead or living away to Xibabla (the underworld).’
