Reconstruction drawings of the archaeological heritage which abounds in the historic kirkyards of Aberdeenshire will be just one of the exhibits on display at the Georgina Scott Sutherland Library, Garthdee from 29 September - 2 December.

A selection of work by Aberdeen City Council Archaeological Illustrator and Gray's graduate, Jan Dunbar, will be displayed alongside original artefacts from Aberdeen and the surrounding area. Shown with preparatory drawings, photographs and finished publications, they will give a glimpse into this fascinating and unusual career.

On show will be one of the only complete local medieval jugs found in Aberdeen. The King St jug was found during building of a new basement of Chivas Brothers at 13 King Street in 1872. The find was reported in the Aberdeen Free Press at the time and then the jug was stored in the basement of that building, surviving more than 100 years in the cellar without being thrown out. In more recent times its home has been the foyer of Aberdeen Art Gallery.

The exhibition will comprise a wealth of other artefacts including: a cremation pot from near Laurencekirk, a number of flints, an early Bronze Age halberd, a medieval antler hammer excavated on Queen Street, a medieval 'buzz-bone' or musical instrument, as well as coins and axe-heads.

Archaeological illustration involves a great deal more than drawing finds. While producing neat, accurate and detailed drawings is a major part of the job, the illustrators at Aberdeen City Council Archaeology Unit are also responsible for all sorts of exhibition and publication work, producing maps and plans, illustrative material for books and educational projects and occasionally helping out on site.

As Jan explains, "The purpose of a find drawing is to convey as much information as possible about the object, and each drawing should be clear and accurate and show one or more sections and a scale. Depending on the object, several different views can be shown at once. Objects are drawn in pencil for archive purposes and in ink for publication.

"Recording on site is meticulous. Every feature and layer is drawn onto a plan, which can be tied into the Ordnance Survey grid. Two tapes are used to triangulate points, positioning features accurately on the plan. Sections are drawn through features such as pits to record all the different layers, and wall faces are drawn to show building sequences and techniques."

Jan concluded, "Interpreting the sites is a job for the archaeologists and historians but visualising their findings has become increasingly important, with the installation of information boards and the continued drive to make exhibitions and publications more appealing to the public. Reconstruction drawings and artists' impressions allow a bit more freedom of expression, although they are all carefully researched and checked by specialists for historical accuracy."

The exhibition has been organised by The Robert Gordon University's Library Collections team in collaboration with the Aberdeen City Council Archaeology Unit. All objects on display are from Aberdeen Art Gallery and Museums Collections.
