Head of Bacchus. Hadrianic Period, 117–138 AD. Kelsey Museum of Archaeology

"Left: Head of Bacchus. Marble, pigment. The image in the middle shows an application of color based on the locations of pigments found on the object’s surface during examination. The image on the right is a hypothetical reconstruction of the finished surface based on similar sculptures and wall paintings.

The traces of red pigment in the hair are relatively easy to see, but we suspected there might be microscopic traces of color in other areas. To find out, we explored the surface of the head for pigment using a Dino-Lite digital microscope as well as multispectral imaging (MSI). To our surprise, we discovered a lot of color, including traces of what could be red lead or cinnabar/vermilion on the inner corner of the mouth, and black and red pigment along the inside of the eyes and in the tear ducts. The biggest surprise was revealed in the MSI imaging: luminescent areas of Egyptian blue in the garland of ivy leaves in the hair.

This physical evidence, along with curators Elaine Gazda’s and Nicola Barham’s knowledge of Roman sculpture and painting, allowed us to create this digital reconstruction of what the Bacchus head might have looked like in full color. Note: the red pigment in the hair was likely underpaint for the final color, while the blue in the leaves was likely mixed with a yellow pigment to create green"

"The site of Tintagel Castle has been inhabited at least since the late Roman period, and a community flourished here in the 5th to 7th centuries. In the 12th century Tintagel gained literary fame when Geoffrey of Monmouth named it as the place where King Arthur was conceived. These Arthurian associations may have inspired Richard, Earl of Cornwall, to build a castle at Tintagel in the 1230s"

Cabezo de Alcalá is an archaeological site located near Azaila, in the region of Aragón, Spain. The ancient name of the city is unknown, although some researchers have suggested that it may have been Sedeisken.

This town was destroyed as a result of the Sertorian War, one of the Roman civil wars of the first century BC. Between 74 and 72 BC, the troops of Pompey laid siege to the town, which supported Sertorius.

In order to breach the fortified enclosure, they constructed a ramp using materials taken from the houses in the outer districts. The ramp enabled them to cross the moat and the walls, allowing them to enter the city and destroy everything in their path. The settlement was never rebuilt.
