The Faerie Queene (excerpt)

It was a goodly heape for to behould,
And spake the praises of the workmans wit;
But full great pittie, that so faire a mould
Did on so weake foundation euer sit:
For on a sandie hill, that still did flit,
And fall away, it mounted was full hie,
That euery breath of heauen shaked it:
And all the hinder parts, that few could spie,
Were ruinous and old, but painted cunningly.
