Cenmar

Cenmar or Cinimmar (Pronounced "Sanimar" in Arabic: سنمار) was an ancient architect in the Persian empire who was requested to build the most beautiful palace for an Arab king among the territories of the Persian kingdom. (See Al-Hirah).
After 20 years, Cenmar finished building the palace, named Khawarnaq (Arabic: الخورنق), and invited the king to see it. It was a real piece of art. After a small discussion between the two, Cenmar told the king two things. The first was about a brick within the palace that would cause the whole construction to collapse if moved, and that he was the only one to know where it lies. And the second was that he could build a palace that moved with the sunlight wherever it went. The king, who got afraid of Cenmar's knowledge of the brick and jealous he might build a bigger and more beautiful palace to another king, ordered his guardians to kill Cenmar by throwing him from up the palace to the ground.
"Cenmar's compensation" is used proverbally in Persian and Arabic countries.
