Krzysztof Dorohostajski, grand marshal of Grand Duchy of Lithuanian, in Krakow 1604

 Salvete Omnes,

yesterday or on the 4th of December but in 1604 AD, the rulers , many lords, magnates and common citizens of  Polish-Lithuanian Commonwealth came to the capital of the realm - i.e.,  Krakow (Cracow), to greet and welcome Constance of Austria as the new wife  of our king, Sigismund III. Constance would wed and be crowned as queen-consort of the Polish-Lithuanian realm.

The Krakow entry was commemorated in the fabulous scroll painting known as the Stockholm Roll - this name is due to the fact that the Swedish king  had the painting taken from the Warsaw Royal Castle in 1655AD and it had been stored in Sweden until returned by prime minister Olof Palme in 1974. 

One of the officials depicted in this gouache painting is senator Krzysztof Dorohostajski vel Dorohostayski (Leliwa coat of arms),

 who was the grand marshal of GDoL during this time. 

Dorohostajski is dressed in a Spanish or Italian dark costume of the period, holding his staff of office

Pan Krzysztof, an authority on war, law and horses, is riding a bay or rather a  chestnut horse, presumably a stallion, himself being a famous writer of a horsemanship treatise, Hippika,  published in 1603, and formerly a winged hussar companion and at that time a captain of  his own winged hussar company. He would participate in the wars against Sweden and Muscovy until his passing in 1615.
Dorohostajski horse's tack appears to be very splendorous and exquisite, gold pieces on the black background, with gold or gilded stirrups.  
The court marshal of GDoL, Piotr Wiesiolowski (Ogonczyk coat of arms),

riding on a chestnut stallion next to Dorohostajski, is dressed in a prevailing then Hungarian style of  costume, his horse furniture more like of the winged hussars, and he has a sword under his thigh.  All gilded and ornamented with precious and semiprecious stones and perhaps pearls. 

                                                                                              ***

Nota bene our then king and groom, Sigismund III Vasa, is depicted as mounted on a dark chestnut stallion 

and his bride and queen to be, Constance of Austria with her royal entourage in the carraige: her mother archduchess  Maria Anna, her sister Maria Christierna and king's sister princes Anna.
