The architectural elements of the Burgos altar are probably the work of Bigarny, as is also the Annunciation group, while the Holy Family must be attributed to Diego de Siloe.
This altar exemplifies the last phase of Bigarny's art, showing that the sculptor had assimilated the Renaissance style: in both decorative elements and also in the modelling of the figures, the Italian influence is now marked.
It is difficult to distinguish the hands of Felipe Bigarny and Diego de Siloe who together contracted for the execution of this altar.
Some scholars think that the design is Bigarny's and the execution de Siloe's.
Филипп Бигарни (~1470 - 1543)
Bigarny, one of the group of artists whom Charles V gathered about him, formulated in his Burgos altar the altar-type of offical art.
