Note 317 — BOOK III.
Thomas Hodgkin translation
The number of times that the charioteers had rounded the goal was indicated by large wooden eggs, which were posted up in a conspicuous place on the spina. It seems that in a corresponding place near the other end of the spina figures of dolphins were used for the same purpose. Upon the Cilurnum gem (figured on page 231) we can perceive four eggs near one end of the spina, and four creatures which may be dolphins near the other, indicating that four circuits out of the seven which constitute a missus have been accomplished by the quadrigae.
