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.

"I don't think that we should allow ourselves to be bullied into thinking that the BBC is only any good, if it reflects the prejudice of the last person who shouted at it." ~AA

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.

A photograph of heraldic stained glass. A central shield is surmounted by a golden coronet and surrounded by a circular golden halo decorated with intertwined studded belts and small roses. The shield is divided into quarters, the upper-left and lower-right of which each display a blue diagonal stripe, running from upper-left to lower-right, on a gold background. The upper-right and lower-left quarters each feature a red background with a white chevron, upon which two red lions in passant posture approach a single red rose from either side. Outside the halo is a regular diamond pattern of plain glass.

Cliff Palace, Mesa Verde National Park, Colorado. #MesaVerde #Colorado #Archaeology #Architecture #Photography
Photograph of semi-ruined dwellings nestling beneath an overhanging cliff. The buildings are constructed from honey-coloured stone, comprising houses, towers, and courtyards. They run from lower-left of frame toward the mid-right, where they are obscured by foreground foliage. The massive overhanging cliff is of similar colour to the buildings, looming over them in a manner that somehow seems both protective and threatening. At the top-right of frame, a patch of sky is largely filled by bright white clouds with small glimpses of blue between them.

Exactly a year since I stopped tweeting and fully committed to this place. So much nicer over here.
A seagull soars in a cloudless blue sky, its wings tipped with black but otherwise pure white. The gable end of my parents' roof encroaches into the bottom of frame.

North Gate of Housesteads Fort, Northumberland. #RomanFortThursday #Housesteads #HadriansWall #RomanBritain #Archaeology #Monochrome #BlackAndWhite #Photography
Black and white photograph of a roman gateway at Housesteads Fort. The bases of two square towers remains, up to a height of four or five courses of squared-off stone. A stone cistern can be seen in front of the left-most tower. Between the towers, a wide opening is punctuated by a central stone pier of square cross-section. The double pathway that it creates is grassed over, as is the land both inside and outside the gate. The wall of the fort, again about four or five course in height, extends on either side of the gateway. In the distance, Hadrians Wall runs in a north-easterly direction toward the leftmost edge of a patch of woodland that occupies the mid-right of frame. Further away, there is another wooded area just above centre-frame, standing in expansive grassland. The sky is mainly clear, but decorated with light cloud.

Arms of Sir Malcolm MacGregor, 5th Baronet MacGregor, in St Conan's Kirk, Loch Awe. Argent an oak tree eradicated in bend sinister proper, upon which a sword bendwise azure supporting on its point a crown gules. For the crest, a lion's head proper crowned or. #Heraldry #Woodcarving #Photography
Wooden carving of a coat of arms belonging to Sir Malcolm MacGregor, 5th Baronet MacGregor. The shield bears an uprooted oak tree, tilted such that its roots are lower left and its branches upper right. Across this lies a sword, its pommel at lower right and its point at upper left. The point of the sword supports a crown with five visible spikes. The whole shield is tilted at 45 degrees clockwise from vertical, and carved drapery artfully crosses its lower portion. Above the shield is a jousting helm, surmounted by a crest comprising, in profile, a lion's head wearing a crown similar to that depicted on the shield. The background is adorned with pinecones and the name MacGregor of Glen Strae is displayed prominently at the bottom of the carving.

Brent Knoll, from Ancient Earthworks & Camps of Somerset (Edward J. Burrow, 1924). #HillfortsWednesday #Watercolour #BrentKnoll #Somerset #NorthSomerset
Black and white watercolour of a conical hill. The base of the hill is wooded, but the top is bare with hints of earthworks; a tall mast juts from the summit into a lightly clouded sky. In the foreground, a lane crosses the frame from lower-left toward mid-right. A few houses and a barn cluster near the foot of the hill, one cottage being particularly prominent toward the right of frame.

Black and white photograph of a seagull, wings extended but pulled back, legs outstretched, leaping from the top of a street rubbish bin, heading down toward the lower right of frame. The bird is white, apart from black markings at the very tips of its wings. In the background, in soft focus, is a whitewashed stone building with a black door and other less identifiable features.
