Jan Danilowicz (1570–1628) – castellan of Lviv, Grand Deputy Cup–Bearer (pidczaszy) of the Crown, from 1614 voivode of the Ruthenian Voivodeship. He was the son of the Lviv standard-bearer Stanislaw Danilowicz and his wife Katarzyna of Tarlowie. Grandfather of the King of the Polish-Lithuanian Commonwealth Jan III Sobieski. The artist portrayed Jan Danilowicz following classical standards of Ukrainian representational portraiture: the figure is facing three-quarters to the right, with the right hand resting on the belt and the left holding the hilt of the sabre. The face is shaped extensively, with loose strokes. The high forehead, the crease between the eyebrows and the concentrated gaze of the eyes suggest a highly educated and sensitive person. The painter conveys the delicate intellect and inner nobility of the portrayed man. Light-coloured spots of the hands and the head dominate in the richly ornamented caftan lined with the dark fur of the red delia and the olive-coloured background. Above on the left, there is a decorative drapery and underneath is the inscription: «Iones Danilowic Palatinus Tenus Russie».
