Question: What King of Prussia was known to make a study of the Seize Quartiers of his courtiers?

Frederick II (German: "Friedrich" ; 24 January 171217 August 1786) was King of Prussia from 1740 until 1786, the longest reign of any Hohenzollern king.  His most significant accomplishments during his reign included his military victories, his reorganization of Prussian armies, his patronage of the arts and the Enlightenment in Prussia, and his final success against great odds in the Seven Years' War.  Frederick was the last titled King in Prussia and declared himself King of Prussia after achieving full sovereignty for all historical Prussian lands.  Prussia had greatly increased its territories and became a leading military power in Europe under his rule.  He became known as Frederick the Great ("Friedrich der Große ") and was affectionately nicknamed "Der Alte Fritz " ("Old Fritz") by the Prussian and later by all German people. <SEP> Paata (Georgian: პაატა ; 1720 – December 1765) was a Georgian prince royal ("batonishvili") of the Bagratid House of Mukhrani of Kartli.  A natural son of King Vakhtang VI of Kartli, Paata was brought up and educated as an artillery specialist in the Russian Empire.  His adventurous life led him, through Prussia, Poland, and the Ottoman Empire, to his native Kartli, where he was in service of King Heraclius II, a son of his half-sister, until he led a plot to kill Heraclius and seize the throne for himself in 1765.  After the conspiracy was discovered, Paata was tried, sentenced to death through decapitation on 5 December 1765 and soon executed. <SEP> Senewosret-Ankh was an Ancient Egyptian vizier of the Middle Kingdom, dating to the end of the Twelfth or to the beginning of the Thirteenth Dynasty, around 1800 BC.  He is known from a number of sources making it possible to reconstruct his career.  He started as 'personal scribe of the king's document and was appointed from there to the "overseer of fields".  From this position he was most likely appointed to the position of the vizier.  As vizier he is known from a statue found at Ugarit.  The statue shows him and his wife Henutsen as well as his daughter Zatamun.  The statue also mentioned that to him was given the "gold of praise in front of all courtiers".  It remains unknown for what reason he received that honour.  A stela now in Florence is dedicated to Senewosret-Ankh by "his steward Keki", one of the administrators of Senewosret-Ankh's estates. <SEP> Seize Quartiers is a French phrase which literally means a person's "sixteen quarters", the coats of arms of their sixteen great-great-grandparents, which are typically accompanied by a five generation genealogy outlining the relationship between them and their descendant.  They were used as a proof of nobility ("the proof of the Seize Quartiers") in Continental Europe beginning in the seventeenth century and achieving their highest prominence in the eighteenth.  For example, Frederick the Great was known to make a study of the Seize Quartiers of his courtiers.  Possession of seize-quartiers guaranteed admission to any court in Europe, and bestowed many advantages.  They were less common in the British Isles, seventeenth-century Scottish examples being the most prevalent.
