An engraved schist plaque from portugese late neolithic (4000 to 3000 BC) described as an idol, back on the museum infos. It's of rectangular shape and the engraving displays geometrical shapes. The top half is projecting some sort of rays from the centre to the exterior, the bottom part is divided in rows filled by rectangles. There's a hole, presumably to were it as necklace on the top center part of the piece. The overall plaque gives a bit the feeling of a dress with a cleavage on top, a belt halfway, and then a bottom part.
