Sharjah24 – Reuters: An unfinished tombstone, a large ceramic vase painted with beeswax, human representations and ancient tools to process corn are artifacts of a collection of 1,305 pieces that have been returned to Costa Rica.

It is the second time the Brooklyn Museum in New York City has returned pieces, some older than 2,000 years, to the central American country.

Tycoon Minor Keith brought the artifacts, looted during the construction of a railway, to the United States in the 19th or early 20th century, along with shipments of bananas.

Archaeologists in Costa Rica have been in awe since the artifacts arrived at the end of last year.

"The tombstone is a piece we have only seen as illustrations in study books here," Daniela Meneses, a researcher at the National Museum of Costa Rica, said at a viewing for the media. "It's amazing to see that piece now. It's very emotional."

It is believed to have been part of a tomb of an important person from a now-extinct civilization.

At almost half a meter high, one of the largest pieces in the shipment is a vase, presumably used to store seeds or water; it is adorned with human figures and peculiar geometric lines, painted with beeswax.

There are still more artifacts from Costa Rica in Brooklyn and in other museums in the United States.

Seven years ago, four sites in the southern part of the country were recognized as World Heritage by the United Nations Educational, Scientific and Cultural Organization (UNESCO).
