Rhodes was besieged by Sultan Solyman in 1522, and at the great assault upon the city, 24 September, the garrison believed they saw John Baptist himself standing on the roof of his own church, waving a banner and encouraging them. It really was the prior’s French cook; and when they found this out, they accused him of making signals to the enemy, and nearly murdered him. At the siege of Rhodes by Mithridates in 88 B.C. the garrison saw the goddess Isis standing on her temple and hurling down a mass of flame on the attacking force. And such apparitions have been common, from Castor and Pollux at Lake Regillus down to Saint George at Mons. Saint George, however, had no business there. He suffered martyrdom at Diospolis, twelve miles from Jaffa, where Perseus delivered Andromeda; and the old legend was transferred to him. It must have been a whale that Perseus killed, according to Pliny’s description of the bones; and, if Saint George had known his business, he would have abandoned Mons and gone out spearing submarines. There is a treatise by Artemidoros on the interpretation of dreams, _Oneirocritica_, which (I believe) is not much read now, yet really is worth reading, as it shows what people used to dream about in the second century A.D. We do not dream now of being beheaded or crucified or becoming gladiators or fighting with wild beasts or being sold as slaves. But apparently these people dreamt oftener of such calamities than of the minor ills of life. Judging by what they dreamt, I should say their minds were not so complex as our own. In interpreting their dreams Artemidoros tried induction, noting down the things they dreamt and what happened to them afterwards. Thus (iv. 31) Stratonicos dreamt he kicked the Roman Emperor: on going out he trod on something, and found it was a gold coin with the Emperor’s image on it. There were two kinds of dreams. If people dreamt of doing anything that they did habitually, it was nothing but a dream and needed no interpreting; but it became a vision, if they dreamt of doing things they seldom did, or could not do. Thus, it was only a dream, when they dreamt of lighting a lamp from the fire on the hearth; but it was a vision, when they dreamt they lit it from the Moon--after dreaming this a man went blind, v. 11, 34. Most people would be content with saying that the thing could not be done, because the Moon was too far off; but Artemidoros goes on to explain that nothing can be lighted from the Moon, as the Moon itself is not alight and shines only by reflexion.
