That houses forme within was rude and strong,
2 Like an huge caue, hewne out of rocky clift,
From whose rough vaut the ragged breaches hong,
4 Embost with massy gold of glorious gift,
And with rich metall loaded euery rift,
6 That heauy ruine they did seeme to threat;
And ouer them Arachne high did lift
8 Her cunning web, and spred her subtile net,
Enwrapped in fowle smoke and clouds more blacke then Iet.
