The present bronze compares closely with small German bronzes dating to the 16th century, such as some illustrated by Chipps Smith (op. cit
.). When Hackenbroch recorded the collection of Leon Bagrit, she attributed the present bronze to Loy Hering and dated it to Augsburg, circa
1525 (op. cit.
). However, Hering's medium of choice was his local limestone and the sculptor did not work in bronze. His limestone on slate relief of Rhea Silvia
in the Victoria and Albert Museum, London, is known in later bronze copies (inv. no. 4888-1858).
