A bull bolts and lunges into the crowd. Men in white, starched dishdashas and women in black, flowing burkhas scream and scatter like animated chess pieces, but soon enough order is restored. I am at the Friday goat market in Nizwa, capital of the Sultanate of Oman back in the 6th century. It is set against the backdrop of the Nizwa fort and the souq, one of the country&rsquos oldest bazaars. There is a diversity of livestock at the &lsquogoat market&rsquo &mdash sheep, cows and very big bulls. The goats are diverse too the white, bearded ones are from Salalah in South Oman, the shaggy, curly hoofed ones are Jebel Akhdaris. Making up the numbers are shaggy any-old goats, grouped together as &lsquoOmani goat&rsquo. The livestock are all being marched counter-clockwise in a circular parade before raucous bidders. Some obstinate animals have to be cajoled to join the show, while others flaunt their haunches.
