what do you call the top of a column
Column At the top of the shaft is a capital, upon which the roof or other architectural elements rest. In the case of Doric columns, the capital usually consists of a round, tapering cushion, or echinus, supporting a square slab, known as an abax or abacus. Ionic capitals feature a pair of volutes, or scrolls, while Corinthian capitals are decorated with reliefs in the form of acanthus leaves. Either type of capital could be accompanied by the same moldings as the base.[2][3] In the case of free-standing columns, the decorative elements atop the shaft are known as a finial.
Totem pole Those from cultures that do not carve totem poles often assume that the linear representation of the figures places the most importance on the highest figure, an idea that became pervasive in the dominant culture after it entered into mainstream parlance by the 1930s with the phrase "low man on the totem pole"[24] (and as the title of a bestselling 1941 humor book by H. Allen Smith). However, Native sources either reject the linear component altogether, or reverse the hierarchy, with the most important representations on the bottom, bearing the weight of all the other figures, or at eye level with the viewer to heighten their significance.[25] Many poles have no vertical arrangement at all, consisting of a lone figure atop an undecorated column.
