In the context where the above tradition occurs, which, as is obvious, relates to the founding of Rome, we meet with another on the same subject as follows: — When Solomon married the daughter of Pharaoh, the Angel Gabriel thrust a reed into the sea, stirring up therewith the sand and mud from the bottom. This, gradually collecting, first shaped itself into an island and then expanded so as to unite itself with the continent. And thus was the land created for the erection of the hut which should one day swell into the proportion of a proud imperial city.
