   Gyrus
   or vivarium; in the Roman legionary camp, the gyrus with the training ring and animal corral. The structure was formed from fifty semicircular cut timbers set upright in a circular trench, probably supporting a framework of cross-timbers. A single entrance passage adjoined the structure on the north-east and had gates at both ends, presumably to control the entrance and exite of animals. It is probable that both horses and men were trained within the gyrus.

   gyrus
   training ring / animal corral Also identified as a vivarium, the only known example of an auxiliary fort containing a purpose-built gyrus/vivarium throughout the whole of the Roman empire is 'The Lunt' fort at Baginton near Coventry. The structure was formed from fifty semicircular cut timbers set upright in a circular trench, probably supporting a framework of cross-timbers. A single entrance passage adjoined the structure on the north-east, which had gates at both ends, presumably to control the animals entering or leaving the main structure. It is probable that both horses and men were trained within the gyrus, the instructor most likely remained in the centre of the ring, while the trainee was walked around the perimeter on the end of a leash.
