In winter, when great numbers of Vlach herdsmen take up their quarters in the town, its population exceeds that of Larissa. It has the appearance of a Mussulman town on account of its mosques (only two of which are in use) and it is a centre of trade in wheat, maize, tobacco and cocoons. The town was in ancient times a celebrated seat of the worship of Aesculapius. Pop. (1889), 14,820; (1907) 17,809; of the department, 90,548.
