Researchers date the sarcophagus mainly to the beginning of the first half of the 11th century, but there are also hypotheses regarding the 10th or 12th century. The carving is made in the same Byzantine style as on the marble sarcophagus of Yaroslav the Wise; in particular, similar images of cypress trees and crosses are used. This type of decoration is common in Byzantine reliefs from the 11th century. A. N. Grabar noted that similar decoration (in particular, rows of arches) is found on some sarcophagi depicted in the Minology of
Basil II miniatures. It associated the slate sarcophagus, like the sarcophagus of Yaroslav the Wise, as an example of
Constantinople sculpture of the first third of the 11th century. According to N. E. Makarenko, the difference in the design of the walls indicates that the two masters made the sarcophagus at the end of the 10th-11th centuries in different manners and is the result of Byzantine influence coming through the Balkans. V. G. Putsko agrees with him, believing that at least two craftsmen worked on the sarcophagus. However, he explains the difference in decor by the fact that the masters did not copy entire compositional schemes, only individual elements. M. K. Karger believes that by the 11th century, local stone-cutters in
Kyiv made sarcophagi for the Kyiv nobility. “Among them, along with smooth-walled ones, sarcophagi are also known, completely covered with
bas-relief carvings.” Although the carving motifs on the sarcophagus are traditional for Byzantine sculpture of the 11th century, they are also found on monuments of the 12th-13th centuries, for example, on reliefs from Smyrna from the late 11th-12th centuries or
Thessaloniki from the 12th-13th centuries. This extends the dating of the slate sarcophagus to the 11th-12th centuries. == Attribution ==
