The roads are much better now that we’re in the plains of Uzbekistan. As in India, taxis are plentiful and cheap, and we sometimes hire a driver for a whole day.

Every car is a potential taxi. Many drivers carry a cheap “taxi” sign that they place on their roof when they want to pick up passengers.

Safety is some concern, though most taxi drivers are very professional. If we’re lucky, there is a seatbelt for the front passenger. Drivers reassure us that we aren’t required to use it, and they carefully avoid using their own outside police checkpoints.

We did have one bad experience with a taxi driver who took us on but then drove unsafely in the opposite direction to drop off some papers to a friend. When this began to take more than five minutes, I objected and we got out of the car to find another cab. Not wanting to lose a fare, the driver threatened the new taxi driver and tried to cut us off when we drove away. I showed my fangs in a way Marcia has never seen, using one of my few words of Russian to tell the driver I would call the police if he didn’t back off.

“Shared taxis” are the best way to move from place to place. One can buy a seat in a car that shuttles between cities for a very reasonable price, since the driver finds other passengers to pay for the return trip. Four passengers plus the driver is considered a full car. For comfort, we often buy all four seats in the car.

Most towns are too small to have regular buses. There are cheap minibus “marshutkas,” but they are very slow because they stop everywhere to let on overweight matrons. Only Tashkent has a subway.

Fuel is expensive and scarce right now. Drivers rarely keep their tank full, preferring to add just enough liters to reach their destination. Although there are some modern filling stations, smaller outfits dispense gas using a bucket and funnel.

There are of course interesting loads. Central Asian people like to sit and drink tea on huge benches. This one is moving to a new home.

Most Central Asia countries have reasonable control on their currencies, and their money can be exchanged freely at least in neighboring countries.

Uzbekistan is the exception. Although one of the richer states due to oil revenues, its “president” has opted to use Soviet-style controls to prevent currency from leaving the country. Travelers must declare all currencies when entering and leaving, and trouble awaits anyone trying to leave with more than they brought in.

The result is inflation and a rampant black market. Everyone from policemen to hotel clerks will eagerly change dollars at the street rate of 2200 Uzbek som, almost 40% higher than the banks. Everyone eagerly accepts US dollars as a parallel currency.

In its wisdom, the Uzbek government has refused to print bills larger than 1000 som, about 40 cents in US currency. A cup of tea costs more than that, and people routinely carry big blocks of bills for significant purchases. (Credit cards are rarely accepted, and charges would be converted at the bad official rate.)

In order to buy airplane tickets, I had a trusted hotel clerk change $360 into local currency. I got back a stack of almost a million Uzbek som, carefully counted and stacked. The clerk at the airport counted them again with a machine and added them to a large stack that represented the day’s sales.

If there is a center to Central Asia, it is Samarkand. It was already a thriving city when Alexander marched through, and it has seen empires rise and fall ever since. A main stop on most Silk Road routes, it also felt the wrath of Genghis Khan, who destroyed everyone and everything when he swept through.

What stands now is due to Timur, the 14th-century despot who rose from obscurity to conquer most of the known world. Although he was almost as brutal as Genghis, he carted off an army of artisans from the lands he conquered. He then set them to work on building a capital city worthy of himself, mosques and madrassas that were unequalled in the world. Out of this came the blue-and-sable mosaic style that sets the tone of Central Asia to this day. Descendents such as Ulug Beg added the great Registan square to Samarkand, perhaps the greatest town square ever built. Babur and later descendents took a version of the art to Moghul India.

Timur didn't do anything small. His Bibi Khanum mosque had arches almost 40 meters (130 feet) high, comparable to the highest Gothic cathedrals. Even the Koran stand is taller than I am. Unfortunately, they did not hold up well in the unstable ground and fierce winds of Central Asia. Perhaps his architects, who tended to have a short life span anyway, did only what was necessary to satisfy the tyrant and avoid the executioner.

Soviet archeologists and then even more the independent Uzbeks have thrown so much money into restorations and reconstructions that it's hard to say any of it is authentic. The current Uzbek “president” styles himself an inheritor of Timur's greatness and has made Timur the nationalist hero, even if the old tyrant wasn't Uzbek. Still, even if it's a bit like Disneyland, it is very beautiful.

The most exquisite is a set of tombs built around the one small minaret that Genghis Khan left standing. The “teardrop mausoleum” that Timur built for his favorite niece and sister is the height of medieval tilework. Timur himself is buried on the other side of town under the world's largest piece of dark-blue jade.

Not all of Timur’s legacy was monumental. His grandson Ulug Beg was one of the greatest astronomers of his time, making a catalogue of stars that surpassed anything in Europe. Nothing remains above ground of his great observatory, but archeologists recently found the bottom third of the great sextant that once continued its arc three stories above.

Although the great monuments are impressive, we made a point to get off the beaten track. The old Jewish quarter stands behind a wall of tourist shops designed to convince visitors that all of Uzbekistan is prosperous and modern. But one step through a well-concealed door took us out of this twilight zone into the real neighborhood where unrestored mosques, neighborhood baths and even a synagogue rubbed shoulders with ordinary people's houses. (Central Asia historically had a thriving Jewish community, but Soviet attitudes drove most of it to emigrate to Isreal.)

Nearby a small mosque marks a spot in ancient Samarkand that has seen continual worship since the 9th century.

Ancient Samarkand occupied a hill called Afrosiob to the northeast, and it was rediscovered and excavated over a hundred years ago. A small museum houses the most impressive murals I have seen from the Sogdian period (8th century CE) – better than those in the Hermitage!

We took a 25-kilometer detour to Hoja Ismail, the shrine of the scholar Ismail al-Bukhari, who made the most accurate collections of the hadith, the acts and words of the Prophet Mohammed. Although it is on the site of a tomb dating back to the 9th century, most of the construction is modern. But it is still very beautiful.

We took a day trip to Shakhrisabz, about 100 kilometers south of Samarkand.  A small town today, it was the home of Timur, who left behind some ruins even larger than those at Samarkand.  Since these have seen only minor restorations, we could imagine a real sense of the immensity of the construction.

The largest ruins were from Timur's palace.  In its day, it had an entrance arch over 40 meters (130 feet) high and towers up to 60 meters (200 feet),  almost twice what remains in this picture.

Shakhrisabz also holds Timur's family graveyard, a collection of imposing mausoleums.  Timur built a crypt there for himself and probably rolled in his grave when his people insisted on burying him in Samarkand.
