Another example:
"Michelangelo, another great religious architect, designed the dome of St Peter's but died before he could erect it. His designs were adapted by later architects. Does this make St Peter's a botched job, a betrayal? No. We experience it for what it is - a great collective religious work in which the individual contributions of Michelangelo, Bramante, Raphael, Sangallo and Bernini are visible, yet at the same time subsumed in the common purpose.

Significantly, Michelangelo for once set aside his habitual rivalries at St Peter's and incorporated into his own contribution designs by his enemy Bramante. This was the place to work together, not against one another."

When you see it, it is really the work of a genius...
