Laser Scanning 1

As well as compositional analysis, a key element of our project is the laser scanning of our selected range of musical instruments from Roman Egypt. The Petrie has some amazing examples of instruments that struggle to survive outside of the arid Egyptian environmental conditions – we have wooden clappers, metal bells, reed flutes and panpipes. Laser scanning these items allows the recreations of these objects, either through 3D printing or through the making of replicas using authentic materials and techniques. This will allow the instruments to be played, giving us the chance to hear the music of Roman Egypt in the 21st century.

The Classical & Archaeological studies department at Kent is equipped with a laser scanner and our technician Lloyd Bosworth joined us up at the Petrie for a day of scanning. The focus of the day’s activities were the Roman copper alloy bells and cymbals from the collection. The scanner sits on top of its own freestanding tripod, and has a fully articulated arm on which the scanning gun sits. This means you can scan objects on a table by pulling on the trigger and moving something similar to a barcode scanner over the artefact. Simple really. Or at least Lloyd makes it look simple – after having a go myself it’s clear that it requires a lot of hand eye co-ordination in order to keep the scanning gun the correct distance from the object, whilst also capturing every surface of the artefact.

However, once I stepped aside it was a successful day, and Lloyd scanned all of our chosen objects. These included a round bell similar to modern sleigh bells – a particular challenge was trying to scan the gap in the surface where the ball-shaped clapper was inserted. Our selection also includes a number of small bells attached to tiny bracelets, which we think were worn by children as an amuletic device (and also perhaps to keep tabs on where they were!). We also scanned a fantastic bell in the shape of the head of Bes, the dwarf god of ancient Egypt who protected mothers and children, and whose worship continued into the Roman period.

Once all the scan data is processed, the digital models of the instruments can be passed to our craft practitioners who can use the highly accurate measurements and surface details to create our replicas. We’ll update again soon on our progress!
