Nicephorus Gregoras has described the Colossus of Justinian (l. vii. 12): but his measures are false and inconsistent. The editor Boivin consulted his friend Girardon; and the sculptor gave him the true proportions of an equestrian statue. That of Justinian was still visible to Peter Gyllius, not on the column, but in the outward court of the seraglio; and he was at Constantinople when it was melted down, and cast into a brass cannon (de Topograph. C. P. l. ii. c. 17).
