A port town that kept its harbour
Ponnani's history is a port's history. Under the Zamorins of Kozhikode it was a Muslim trading centre and military headquarters; Portuguese raids in 1507 and 1525 damaged it, a Treaty of Ponnani followed in 1540, and the Dutch opened a factory there in 1604. It was also a seat of learning, called the Little Mecca of Malabar, where the Arabi Malayalam script is said to have begun.
The trade that remains is the one at the river mouth. The town is one of the state's major fishing centres, and its harbour lands fish for merchants and the hotels, kitchens and traders who buy from them. Speed matters, and buyers ask before they come.
That makes the reply rung of the ladder the busiest. The messages to plan are the ones a merchant starts: the van time and the invoice to buyers who agreed, and the morning list only to buyers who asked for it.
