It's always a pleasure to come across fan vaulting. This way of supporting and embellishing a stone roof is peculiar to English Gothic and dates from the years around 1500. This particular example is in the south porch of Cirencester church and consequently is invariably lit by a raking light from the entrance: often they are lit by artificial light to show off their beauty. It received some restoration in 1865 by George Gilbert Scott and he, doubtless, simply made good what he found.
