Description:
The title Analemma refers to the diagram of the sun's position in space when observed from a fixed location on Earth at consecutive times in a year. When seen horizontally, this tracing of the sun's orientation resembles Figure 8, which is also a symbol of infinity.
Our Industrial societies condition humans to perceive time linearly, as an intangible omnipresence in an infinite space. The Analemma series is a portrait of a path of light that allegorically crystalizes the passage of time, as a material object that allows connecting the past, present, and future through the physical substance.
This body of sculptures consists of twelve glass pieces varying in size. The centerpiece in the series is a figure 8 glass sculpture emerging in stages from a spheroid and gradually morphing step by step back to the same sphere. Each sculpture in the arrangement embodies a phase of light as it appears to reflect from a concave mirror circling a fixed light source.
In the Analemma series of glass sculptures, Rostami and a team of glass blowers developed a technique to trap the air inside molten glass and form the interior bubble by timing its cooling-off period and applying slight exterior pressure. During this process, they captured the liquefied geometric forms inside the solid glass.
These sculptures act as vessels, windows, light instruments, and lenses that can show both micro and macro visions to transform the perception of their surrounding space.

When light rays hit the curved surface of a rotating concave mirror, they bend into different spatial forms, one of which looks like figure 8 similar to an Analemma.
