Bit of a cheat for #RomanFortThursday this time, with a section of wall from Isca Dumnoniorum (Exeter). Built around CE 200, the city wall shown here encloses a rather larger area than the original wooden-walled legionary fortress of CE 55. #Archaeology #RomanWall #RomanBritain #Exeter #Photography
Photograph of a stretch of wall, two or three metres in height, running from the right foreground to the left middle distance, with grass in front. A tree stands at the left of frame, on this side of the wall. In its closest section, the upper two thirds of the wall are of original roman construction, comprising rectangular purple stones of volcanic origin (Rougemont Trap) laid in regular courses. The lower section represents later underpinning (the ground level having been lowered) in a red coloured stone (Heavitree Stone) and is of a much rougher and more irregular construction. Further away, closer to the tree, the roman work has been replaced or patched with medieval masonry comprising a rather random assemblage of smaller stones.

Oceanus, in the Alcazar de los Reyes Cristianos, Cordoba. #MosaicMonday #Archaeology #Mythology #Photography
Photograph of a mosaic depicting the head of the Titan Oceanus. He has a droopy moustache, a pointy beard, and appears to have an octopus and crab claws emerging from his long shaggy hair. He is surrounded by marine life, including fish and what may be shrimps.

Arms (possibly subtly erroneous) of William Keith, 2nd Earl Marischal of Scotland. Stained glass in the Great Hall of Stirling Castle. Argent a chief paly of six or and gules. #Heraldry #Stirling #Scotland #StainedGlassSunday #Photography
A photograph of heraldic stained glass. A central shield is surmounted by a golden coronet and surrounded by a circular golden halo decorated with stylised fronds and small saltire-bearing roundels. The shield is largely white, save for a band of six vertical stripes, alternating gold and red, occupying its upper third. Outside the halo is a regular diamond pattern of plain glass.

Doorways - Pueblo Bonita, Chaco Canyon, New Mexico. #ChacoCanyon #NewMexico #Archaeology #Architecture #Photography
Photograph showing a series of doorways receding into the distance, each within the frames of the closer ones. The doorways are rectangular and open into mortarless walls constructed from densely-stacked thin stones of a light honey colour.

Two views of a Common Darter. #Dragonfly #FlyDay #Insects #Bugs #Nature #Wildlife #MacroPhotography #Photography
A red dragonfly perches upon a rock in three-quarter profile, facing toward the viewer's left and illuminated by strong sunlight. Its wings are spread and its front legs are slightly raised. The rock is rough and mainly light brown with patches of white, hosting a small growth of lichen on its shady side. In the background can be seen assorted foliage in soft focus. Extreme close-up of a red dragonfly in left-facing three-quarter profile, perching upon a rock in strong sunlight. Its eyes and body dominate the image, while its wings extend beyond the frame on both sides. Its front legs are slightly raised and individual spines can be distinguished along their length. The surface of the rock is rough and its colour is light brown. Behind, foliage is defocussed to the point of abstraction, forming a light green backdrop to contrast dramatically with the insect's coluration.

Remains of a military bathhouse of the mid-Severan period, Vindolanda, Northumberland. #RomanFortThursday #Vindolanda #RomanBritain #Archaeology #Monochrome #BlackAndWhite #Photography
Black and white photograph showing the ruins of a roman military bathhouse. Walls stand several courses high, surrounding an open area that would once have formed part of the hypocaust system. A number of pillars still stand, but the floor they would have supported is missing. Beyond the building, in the distance, is a landscape of grass and occasional trees. The sky above is a featureless white expanse.

"The immense stone rampart of Dolebury Camp, at the North-East angle" from Ancient Earthworks & Camps of Somerset (Edward J. Burrow, 1924). #HillfortsWednesday #Watercolour #Dolebury #IronAge #Somerset
Monochrome watercolour showing a massive stone rampart at left, separated by a ditch from a lesser rampart toward the lower-right of frame. In the distance, fields lead down to the Bristol Channel, beyond which is glimpsed the coast of South Wales. The sky appears laden with cloud.

Rainbow over Loch Leven, Ballachulish. #Rainbow #LochLeven #Highlands #Scotland #Photography
Snatched photograph of a rainbow hovering low over a sea loch. In the foreground are trees, in the midground two sailboats on the loch, and in the distance grassed and wooded hills. The rainbow stands out brightly against the latter. Above, the sky is an ominous grey.

SUPERB and angrily unvarnished response, by former BBC chairman, Lord Patten.

Eros & Psyche, in the Alcazar de los Cristianos Reyes, Cordoba. #MosaicMonday #Archaeology #Mythology #Photography
Photograph of a mosaic depicting two mythological figures embracing. The figure on the left (Psyche) is female and faces away from the viewer, wearing a rather diaphanous dress. She seems to have delicate butterfly-like wings emerging from her upper back. The figure on the right (Eros) is naked apart from a parted cloak and faces toward the viewer. He sports a pair of large bird-like wings on his back. The colour palette includes flesh tones, white, black, and various golden brown hues.
