One does not soon forget the first sight of the full coliseum. In the centre is the sanded arena, surrounded by a high barrier. Around this rises the graded succession of stone benches for the people; then numbered seats for the connoisseurs; and above a row of boxes extending around the circle. The building holds, when full, some fourteen thousand persons; and there is rarely any vacant space. For myself I can say that what I vainly strove to imagine in the coliseum at Rome, and in the more solemn solitude of the amphitheatres of Capua and Pompeii, came up before me with the vividness of life on entering the bull-ring of Madrid. This, and none other, was the classic arena.
