Harla skeletons are often buried with pots resting above their head. Inside the pots are black sand (why? nobody knows), necklaces of gemstones, and silver coins that are slightly smaller than a dime. There seems to be writing or designs on the coins but they're old and poorly minted, and if they ever once said anything, they're unreadable now. The necklaces are usually agate, but also ruby and amber. The style of the pots, coins, and jewelry are the same both in the mountains around Harar and in the Somali lowlands all the way to the Red Sea. This has convinced Muhammed Dake that the sites all belong to the same culture.

Legends say the center of this civilization was around Harar, which makes sense since it has the best land in the region. The kings of Harla were wizards who boasted about their powers. One said he'd make a river of milk between two mountains; another bragged he could make a sorghum plant that could be laid down and be used as a highway all the way to the Awash River, 150 miles away. Allah got angry at all this and destroyed them. A few Harla survived and fled to Kush in the Sudan, the site of another great civilization.

The Hararis are believed to be descended from the Harla. The closest Harla site to Harar is at the Oromo village of Harla, from which the civilization gets its name. We have no idea what the Harla called themselves. When Allah destroyed the civilization and the survivors fled to Kush, one woman stayed behind to found the modern town of Harla. With a population of about 2800, it's a half-hour drive from Harar on a winding mountain road that offers sweeping views of the lowlands to the north.

When we arrived at the modern Harla I saw the Oromo there looked and dressed a bit different than other Oromo I'd met. The women didn't wear the usual Western-style striped shirt that's almost a uniform for Oromo women in this region. Was this a remnant of their different origins? It's hard to say, but the modern residents of Harla say they're of different origins than the rest of the Oromo. Over the years they've taken on Oromo customs and the Oromo language, but still consider themselves a distinct people.

Like everywhere else, Muhammed Dake seems to know everyone in Harla. Some of the villagers showed us the ruins. There are thick walls of stone cemented together with a type of plaster that's still strong after centuries of weathering. Some remain standing above the height of a man, and one field is filled with a network of walls, showing the ancient town was a cluster of closely built structures. In one spot, a tree has grown up through a wall. Plants may be slow, but are almost unstoppable. This tree cracked through the tough Harla plaster and grew around the ancient stones, lifting them into the air as the tree grew. Now the building looks like it's frozen in the middle of an explosion, its stones suspended several feet above the ground. The local kids love to climb this tree, using the Harla stones embedded in the wood as footholds.

Muhammed Dake believes the Harla people were pagan, judging from how they built their graves. They don't look either Muslim or Christian. But the Harla village presents another mystery. At one ruin that looks constructed in the Harla style, a villager pulls away some bushes along one wall to reveal a niche. To confirm my suspicions he raises his hands and says "Allahu akbar" (God is Great). It's a miqrab, the niche in a mosque that points the way to Mecca. And it does point the right direction. Is this mosque from the Harla times? If so, the Harla were the first Muslims in the region, predating the Harari people who can trace their roots back to the tenth century.

Or perhaps it's a later ruin. So little is known about the Harla, and so little archaeological research has been done here, that for the time being all we have are legends of a race of giants who once ruled the land.
