 fifty yards seaward of the villas to check the onslaught of storms. 

 Of the rich men who had these houses made for their pleasure, 

 Horace had this to say : 



"You on the verge of death contract for blocks of marble to be 

 hewn, and unmindful of the grave, are rearing mansions and are all

 Baiae; for not enough does the bound of the land enrich you." 



On the east side of the Gaiola promontory is a row of submerged 

 structures which the fishermen have always regarded with mixed 

 feelings. In calm weather they are a rich hunting ground, but in a 

 storm they are a menace to small boats. These obstacles rise from 

 twenty-five or thirty feet of water to within a few feet of the surface 

 and are regularly spaced. Close investigation has shown that they 

 are made of concrete ; they are, in fact, the piers of a Roman harbor

 he examined changes In sea level that have 

 taken place since Roman times.
