The Coat of Arms of 1615 is the ennobled, i.e. registered, arms of the family in the archives acknowledging the hereditary titles: Lord Jankovsky, Baron of Vlasim.
On top are formal acknowledgments by the Holy Roman Emperor, by the King of Hungary (on the left) and by the King of Bohemia (on the right).
In the center is the Family's Coat of Arms, shield and crest, supported by two lions which represent the Kingdom of Bohemia. The Coat of Arms includes: a Helmet representing ancient knighthood; Mantling which depicts the knight's robe torn in battle; the family's Crown of Gold as a symbol of the power to govern granted by the King; the Family's Crest of Eagle Feathers, the Twin Vultures Heads and the Family's Colors that would have flown in battle. Within the Family's Shield is the family's ancient Coat of Arms of the Black Eagle and the Coat of Arms of the Twin Vultures.
On the bottom left are the family's other historic symbols: the Fleur de Lis and the Black Eagle in a gold field which refer to ancient lineage to the Princely House of Vlastislavicu, the ancient Kings of Bohemia and Emperor Charlemagne. Next is a War Drum and Knight's Armor which refer to ancient Battles and Knighthood.
On the bottom right are two War Drums and Knights Weapons that refer back to the two brothers who were knighted. Other symbols relate to past roles as King's Administrators, the Arch Bishop and the Cardinal of Prague.
