("Lives of the Twelve Caesars," Caligula, p. 283).

"It seems generally agreed," writes Forester, the translator of
Suetonius' Lives, "that the point of the coast which was signalised by
this ridiculous bravado of Caligula, somewhat redeemed by the erection
of a high house, was Itium, afterwards called Gessoriacum and Bononia

p. 283).

For many centuries this tower called Turris Ordens, Turris Ardens, or

A description of the tower is given in the "Memoirs of the Academy of

by the Romans, was octagon. It was entirely abolished about a hundred
years ago, but, fortunately, a drawing of it, made when the lighthouse
was still perfect, is still in existence, and has been exhibited to the
Academy by the learned Father Lequien, a Dominican monk, native of

feet. It contained twelve entablatures, or species of galleries, on the
outside, including that on the ground floor. Each gallery projected a
foot and a half further than the one above it, and consequently their
size diminished with each succeeding gallery. On the top fires were
lighted to serve as a beacon to vessels at sea. A solid foundation was
formed, not only under the lighthouse, but for some distance beyond the
external walls. It was constructed of stones and bricks in the
