An oval dome is a dome of oval shape in plan, profile, or both. The term comes from the Latin ovum , meaning "egg". The earliest oval domes were used by convenience in corbelled stone huts as rounded but geometrically undefined coverings, and the first examples in Asia Minor date to around 4000 B.C.
The tambour on which the dome rests dates to between 1090 and 1100, and it is likely that the dome itself was built at that time. There is evidence that the builders did not originally plan for the dome and decided on the novel shape to accommodate the rectangular crossing bay, which would have made an octagonal cloister vault very difficult.
[112] [113] There are two theories about the shape of this dome: a Byzantine-style dome on spherical pendentives with a ring of windows similar to domes of the later Justinian era, or an octagonal cloister vault following Roman trends and like the vaulting over the site's contemporary chapel of Saint Aquiline, possibly built with vaulting tubes ...
Analytical approaches were developed and the ideal shape for a dome was debated, but these approaches were often considered too theoretical to be used in construction. The Gothic ribbed vault was displaced with a combination of dome and barrel vaults in the Renaissance style throughout the sixteenth century.
A geodesic dome is a hemispherical thin-shell structure ... Off-the-shelf building materials (e.g., plywood, strand board) normally come in rectangular shapes ...
In architecture, a pendentive is a constructional device permitting the placing of a circular dome over a square room or of an elliptical dome over a rectangular room. [1] The pendentives, which are triangular segments of a sphere, taper to points at the bottom and spread at the top to establish the continuous circular or elliptical base needed for a dome. [2]

Elliptical domes have many applications in architecture; and are useful in covering rectangular spaces.The oblate, or horizontal elliptical dome is useful when there is a need to limit height of the space that would result from a spherical dome.
