It took Michelangelo from 1508 to 1512 to paint the Sistine Chapel ceiling. On numerous occasions, The frustrated Pope Julius II and the frustrated Michelangelo had the following verbal exchange.
Pope Julius II -- "UT MOS VOS PLATO AN TERMINUS?
Michelangelo -- "UT EGO SUM PERFECTUS!!
Loose translation:
PP Community -- "When will you make an end?
PP Dev Team -- " When we are finished!!
A work of art takes patience on the part of both parties and look what a long lasting thing of beauty the Sistine Chapel is .
Yes, after all of this time I expect a great work of art .
