Kircher's Spiral represents a unique work for the artist in scale, material and ambition of presentation. The patinated brass sculpture is 13 x 13 x 21 inches and polished stainless steel base is 17 x 25 x 10 inches.

Poggioli's preceding works came from research into the history of IUDs and medical industry's patents around female reproduction. The multi-year project began with a residency at SPACES in collaboration with Dittrick Medical History Center in Cleveland, followed by Kohler Arts/Industry Foundry Residency and in 2020 and 2024. Kircher's Spiral was cast during her residency in 2024, and first presented with a different pedestal in 2025 at the Fine Art Centre in Colorado Springs. The piece has since been re-patinated and paired with a stainless steel base.

Kircher's Spiral continues Poggioli's combining of industrially fabricated sculptural forms inspired by scientific inquiries. The work is inspired by a device by the same name, depicted in drawings from Athanasius Kircher's Musurgia Universalis 15th century text on sound, acoustics and architecture. Kircher proposes the spiral structure to be set inside architectural spaces or even as hand held devices, suggesting them as useful for thieves or "eavesdroppers" (possibly the origin of the word). Poggioli on the work:

"Earlier in the text [Kircher] studies human anatomy - at least assumptions of anatomy at the time - and seems to draw connections between spiral forms in the body (such as the cochlear) and their ability to potentially generate or transmit sound. I think it's ... interesting as a metaphor for surveillance - particularly as it relates to medical surveillance and architectural surveillance - two phenomena which exist at different scales but potential operate through similar structures."
