Some recent sketches of the Roman Baths in bamboo dip-pen and pencil, with watercolour washes. The Baths are a great winter sketching location; outdoors but warmed by the thermal springs, and with lots of passing people to add interest and life. The hot water that’s bubbling up fell as rain on the nearby Mendip hills around 10,000 years ago; since then it’s filtered down through rock to a depth of two miles (hence the heat) and travelled fifteen miles cross-country!
