pilaster
Let an agent explain pilasters and their form and use, distinguish them from related elements, identify them in architectural styles, and support learning architectural vocabulary.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain pilasters and their form and use, distinguish them from related elements, identify them in architectural styles, and support learning architectural vocabulary.
A shallow rectangular column or pier projecting only slightly from a wall, with a base, shaft and capital like a column but primarily decorative or lightly structural, used in classical, Renaissance, Baroque and later architecture to articulate facades, frame openings and suggest the classical orders, and distinguished from engaged columns, which are round, and from lesenes, which lack base and capital; pilasters are a standard element of architectural vocabulary.
What it is for: Flat decorative columns on walls.
It can be explain form and use; distinguish related elements; identify in styles; support learning.
