SPEC'ULA (σκοπιά, σκοπή). A watch-tower, on which guards were regularly stationed to keep a look-out and transmit signals. (Varro, L. L. vi. 82. Liv. xxii. 19. Cic. Fam. iv. 3. Id. Verr. ii. 5. 35.) The illustration (Specula/1.1) represents a coast view, from a painting of Pompeii, with five watch-towers situated upon as many eminences, very similar to those with which the Italian coasts of the Mediterranean are now furnished.
