 On some temples, the steps extend only across the front façade, or they may wrap around the sides for a short distance, a detail that is called a return, as seen at the temple of Despoina at Lycosoura.It is common for the hidden portions of each level of the stereobate to be of a lower grade of material than the exposed elements of the steps and the stylobate; each higher level of the crepidoma typically covers the clamps used to hold the stones of the lower level together.The lower margins of each level of the crepidoma blocks are often cut back in a series of two or three steps to create shadow lines; this decorative technique is termed a reveal.
