The aqueduct, near Lincoln’s Nettleham Road, has been known about for centuries, and archaeological investigations of it were carried out in the 1950s and 70s, with no firm evidence for their ever carrying water being found. However, with the recent start of a housing development on the site, the time came for sections of the piping to be removed and studied thoroughly.

Excavations also revealed that a road thought to have been a Roman construction is in fact post-medieval.

Simon Johnson, principal archaeologist at Pre-Construct Archaeology, who carried out the work, explained that visible calcium deposits suggest the pipes did carry water.

“There’s been persistent questions over whether the aqueduct ever functioned,” he said. “We’ve got at least one section where there is furring around the full circumference, suggesting it was used. Who knows for how long? You’re looking at decades to produce that sort of deposit, I should think.”

But he never lost his first love. Over a 30-year period, he traveled to the Middle East, Asia and Europe, amassing a collection of antiquities that has led to a new exhibit at the Hallie Ford Museum of Art, "Ancient Glass: Selections from the Collection of Richard Brockway.

The works on view at Hallie Ford's Study Gallery are small but precious: drinking vessels, tableware, toiletry vessels, beakers and storage bottles from Egypt, the Near East, Greece and Rome, selected to demonstrate the evolution of glass artists' skill and mastery of glassblowing techniques.

Although not considered valuable in their own time, the works have amassed value over time.

"Everything in here is very functional, very utilitarian," Olbrantz said.

"These pieces would have been like our dishes, our pots and pans."

Still, these are among the earliest glass works in history, often simple but elegant in their shapes and speaking to us across thousands of years of history.

Little is known about the early years of glass, although by 2,500 BCE, solid glass beads and amulets were being made, and the oldest fragments of hollow glass vessels appeared in the 16th and 15th centuries BCE in Egypt and Mesopotamia.

At the beginning of the 18th century BCE, Egyptians developed a method for producing hollow glass vessels, making a core mold of compacted clay or dung and winding molten glass around it.

Among the notable pieces in the exhibit is a gleaming blue Ushabti from the New Kingdom. The tiny mold-cast work is a mummy-shaped figure meant to be placed in a tomb to do the work of the deceased in the afterlife. A complete collection would consist of 401, one for each day of the Egyptian year, plus 36 foremen.

A small but striking piece is the Eye of Horus, a mold-cast work of the late period, probably originally found on a statue or statuette of Horus, the falcon-headed god of Upper and Lower Egypt.

Among the Roman works is a large single-handed pitcher, from the first through third centuries CE, a work that Brockway has donated to the Hallie Ford Museum. The free-blown piece has an applied neck coil and handle.

Among the largest pieces is a Light Blue Cinerary Urn, a Roman work from the first through third centuries CE, a free-blown work.

The urn was used to hold cremated ashes but has transcended its mundane past to become a work of art visibly touched by the centuries.

A companion piece, also elegant and simple, is a light blue elongated storage vessel, a Roman work from the fifth to sixth centuries."
