ABU DHABI, United Arab Emirates (AP) — Stepping into the Louvre Abu Dhabi, one of the first artworks a visitor sees is a two-headed Neolithic statue from Jordan, one of the oldest known in human history. That duality — looking back and toward the future, encompassing both East and West — is a theme that extends throughout the new museum, which is opening to the public on Saturday after a decade of delays and questions over laborers' rights. The conservative mores of Abu Dhabi, the capital of the United Arab Emirates that's more buttoned-up than freewheeling Dubai, can be seen in the relative absence of pieces depicting nudity.
