Beheld a grotto vast in depth and size,
Whose high straight sides forbade all hopes of flight:
The fractured roof gave ample space for light,
Through which in gorgeous guise the day-star shone
On many a lucid shell and brilliant stone.
Through pendent spars and crystals as it falls,
Each beam with rainbow hues adorns the walls,
Gilds all the roof, emblazes all the ground,
And scatters light, and warmth, and splendour round.
