San Cecilio, Granada Cathedral. #StainedGlassSunday #Cathedral #Granada #Andalucia #Spain #Photography
Photograph of a circular stained glass window depicting a man wearing a red tunic and a blue-lined green cloak. His right hand is raised in benediction and he holds a large book with blue and gold decoration in his left hand. His bearded face looks toward the viewer's left and behind his head is a circular blue halo, edged in gold. The remainder of the background comprises a repeating pattern of gold flowers and black quatrefoils, the whole being surrounded by a circular border decorated with geometric shapes in multiple colours. The uppermost portion of this border is given over to the legend "S.CECILIO" in red lettering against gold.

Little Egret on the Guadalquivir, Cordoba. #FlyDay #Egrets #Birds #Nature #Wildlife #Cordoba #Guadalquivir #BirdPhotography #NaturePhotography #Photography
Photograph of a white egret (a species of heron) standing in a fast-flowing sage-green river. Behind the bird, can be seen a stone wall and dark green foliage. More dark green foliage occupies the right foreground. The bird has a long neck, which it holds erect, a black bill, and a white plume behind its head.

Lock and Key, at the Vindolanda Museum. #RomanFortThursday #Archaeology #Vindolanda #Northumberland #RomanBritain #Locks #Keys #Woodcarving #Photography
Photograph of a chunky wooden key with four teeth, resting upon a section of the wooden lock into which it presumably once fitted. The lock is rectangular in shape, with a large transverse groove from which lead three narrower longitudinal grooves. A circular hole may be seen at each end of the lock.

View to the East from Dunadd Hillfort, Kilmartin Glen, Argyll and Bute. #HillfortsWednesday #Archaeology #Prehistoric #IronAge #Picts #Pictish #Scotland #Photography
Photograph taken from near the top of Dunadd Hillfort, looking East along the River Add toward distant wooded hills. In the foreground, tussocky hillside drops away, exposed rocks peppering the scene. Immediately below can be seen the roof of a house, beyond which the river leads away from the viewer through green fields in which black cows graze. Above the hills, the sky is dominated by dark clouds portending a downpour.

San Pedro Pascual, Granada Cathedral. #StainedGlassSunday #Cathedral #Granada #Andalucia #Spain #Photography
Photograph of a circular stained glass window depicting a man in ecclesiastical dress, looking slightly downward and toward the viewer's right. His mitre and robe are both green, the former decorated with bands of gold and primary-coloured jewels, the latter with a similar collar. He wears a white pallium, carries a golden crozier in his right hand, and a small red book in his left. Both hands are clad in purple gloves. Tucked in the crook of his left arm is a sword, while his right hand is adorned with a golden ring on its third finger. Behind his head is a red halo, the remainder of the background comprising a regular pattern of circle-in-square and fleur-de-lis-in-hexagon motifs. The whole is enclosed within a circular border, the top half of which is patterned with red circles, orange rectangles, and blue lozenges; the lower half bears the legend "S.PEDRO.PASCVAL" in red lettering against gold.

Burns Monument, Alloway. #BurnsNight #RobertBurns #Poetry #Architecture #Alloway #Ayrshire #Scotland #NationalTrustForScotland #Photography
Photograph looking up to a hillside garden featuring asdorted trees and shrubs behind a stone wall. In the right foreground, an ironwork gateway through the wall bears a sign proclaiming the "BURNS MONUMENT AND GARDENS" and beyond this stands in centre frame a small lodge building. Further up the hill, toward the top left of frame, stands a tall circular monument of neo-classical design, comprising nine slender fluted columns with corinthian capitals, supporting an entablature upon which stands a gilded sacrificial tripod. The sky behind is blue with wispy clouds and the scene is illuminated by bright sunshine.

Felix Klein lectured “On Hilbert’s first note on the foundations of physics" at the Mathematical Society of Göttingen #OTD in 1918. He included excerpts from letters in which he and Hilbert give priority to Emmy Noether’s results on conservation of energy in general relativity. (1/n) 🧪 ⚛️ 👩‍🔬
Black and white photograph of Emmy Noether. She is standing just behind an ornate chair, wearing a white striped blouse with puffy shoulders, a fluffy bow at her neck, and a heavy long skirt cinched with a belt. Her dark hair is pulled back and she is looking a bit to the photographer's right.

Arms of Matthew Stewart, 2nd Earl of Lennox. Stained glass in the Great Hall of Stirling Castle. Quarterly, 1 & 4 Earldom of Aubigny; 2 & 3 Stewart of Darnley. Overall an inescutcheon for the Earldom of Lennox. #Heraldry #CoatOfArms #Stirling #StainedGlassSunday
A photograph of heraldic stained glass. A central shield is surmounted by a golden coronet and surrounded by a circular golden halo decorated with fleurs de lis, roses, buckles, and foliage. The shield is divided into quarters, the upper-left and lower-right of which each show three golden fleurs de lis on a blue background within a red border that is decorated with eight golden buckles; the upper-right and lower-left quarters, meanwhile, each show a horizontal band, checkered in blue and white, against a gold background within a red border whose inner edges feature cup-shaped indentations. Covering the centre of the shield is a smaller shield that displays four red roses arranged around a red saltire on a white background. Outside the halo is a regular diamond pattern of plain glass.
