OXFORD . HISTORY of SCIENCE MUSEUM – GRAFFITI, SYMBOLS, & SCRATCHINGS
The History of Science Museum in Broad Street, Oxford, has a wonderful collection of scientific instruments dating from the Middle Ages to C19. There is a rich hoard to be investigated. As you enter, you will see an outstanding display of the many instruments that over the ages have been used to measure the passage of time. A superb pair of armillary spheres is / are featured HERE. Only the Museo Galileo in Florence has given me such pleasure.

GRAFFITI, SYMBOLS, & SCRATCHINGS
On each side jamb of the entrance to the Museum, there is a fine collection of graffiti of several kinds. Below is a selection of the marks from either side, left first. These include names and dates, with a Bull (1753) on one side, and a later Bull (1891) on the other; and a couple of probable mason’s marks, together with random scratchings accumulated over time.
MARIAN MARKS and PROTECTION (APOTROPAIC) SYMBOLS
By C17 the concept of thwarting evil by means of incised marks on churches and other buildings (eg the TITHE BARN Bradford-on-Avon) was weakening, yet superstition and the fear of evil lingered on. This building – the original Ashmolean – dates to the late C17. By this time, many medieval incised devices – eg scratch dials – had become things of the past. However, to some extent the comfort of cutting marks to ward off evil persisted. This would explain the various Marian marks VV (Virgo Virginum) on the jambs.
There is also a good collection of compass-drawn circles of varying completeness, accuracy, and depth. In medieval times these were the simplest form of demon trap, luring evil inside a circle from which it could not escape. The principle continued in later centuries.
