"Charles V (Spanish: Carlos I; Dutch: Karel V; German: Karl V.; Italian: Carlo V; French: Charles Quint; 24 February 1500 ? 21 September 1558) was ruler of the Holy Roman Empire from 1519 and, as Charles I, of the Spanish Empire from 1516 until his voluntary retirement and abdication in favor of his younger brother Ferdinand I as Holy Roman Emperor and his son Philip II as King of Spain in 1556."--Wikipedia.
"Signer's works have acquired the label 'time sculpture.' They share traditional sculpture's concern with the crafting of physical materials in three dimensions, but they extend that concern into what may or may not be characterised as the fourth dimension: the dimension of time. Time sculpture investiges the transformation of materials through time, focusing the viewer's attention on the experience of the event, the changes wrought, and the forces involved."-- P. 9.
