Gavaksha

[6] In these cases it can become an elaborate cartouche-like frame, spreading rather wide, around a circular or semi-circular medallion, which may contain a sculpture of a figure or head.

Here, and in many similar early examples, the interior of the arch in the motif contains low relief lattice imitating receding roof timbers (purlins).

[8] The rock-cut Lomas Rishi Cave was excavated during the reign of Ashoka in the Maurya Empire in the 3rd century BC, for the Ajivikas, a non-Buddhist religious and philosophical group of the period.

The immediately neighbouring cave in the same rock face has a plain undecorated recess at the entrance, which originally may have held a porch of similar design in plant materials.

Often the areas around these window or gable motifs have bands of latticework, apparently representing lattice railings, similar to those shown edging the balconies and loggias of the fort-palace in the relief of Kusinagara in the War over the Buddha's Relics, South Gate, Stupa no.

This is especially the case at the Bedse Caves,[10] in an early example of what James Fergusson noted in the nineteenth century: "Everywhere ... in India architectural decoration is made up of small models of large buildings".

[11] At the entrance to Cave 19 at Ajanta, four horizontal zones of the decoration use repeated "chaitya arch" motifs on an otherwise plain band (two on the projecting porch, and two above).

It has only two of the traditional projections imitating purlin beam-ends, and a wide decorative frame that spreads over several times the width of the actual window opening.

[15] Early examples include the Buddhist shikhara tower at the Mahabodhi Temple, Bodh Gaya, where the motifs cover most of the surface but do not actually interlock.

The bare castle-like appearance of the central square tower today probably does not reflect the original design, as the upper parts of the structure around it are missing.
