Vote #Orpiment for its role in global art history! #MinCup26 #arthist Consider this personification of wisdom from Kashmir or western Tibet:
Fragmentary Leaf from an Ashtasahasrika Prajnaparamita Sutra
Artist: Unidentified Artist, Kashmiri
Date: 12th century
Culture: Kashmir or western Tibet
Medium: Gold, lapis lazuli, cinnabar, indigo, and orpiment pigments and black ink on paper
Dimensions: Image: 8 1/16 × 6 1/2 in. (20.5 × 16.5 cm)
Classification: Paintings
Credit Line: Gift of Chino Franco Roncoroni, in celebration of the Museum’s 150th Anniversary, 2020
Object Number: 2020.74.2
Curatorial Department: Asian Art, The Met

"This painting depicts the personification of the wisdom text Prajnaparamita. She is represented in six-armed form, the central hands are held over the heart in a variation of the dharmacakramudra, whilst her upper hands display the sacred book (pustaka) and the thunderbolt scepter (vajra), whilst her lower hands hold a rosary (mala) and gesture boon granting. She wears golden jewelry on her body and a tripartite diadem adorns herhead, which is framed by a red halo. A girdle, seemingly of strings of pearls, secures her waistcloth, beautifully decorated with large red rosettes in blue hexagonal frames. Slender ribbons fly through the air, one supporting a blue lotus bloom and stem. She is seated in a mediation posture, enthroned on a golden lotus and she is encircled in a rainbow colored nimbus. Particularly noteworthy is the tonal modelling of the bodily forms, heightened with finely controlled orange-red lines. The swelling breasts and constricted waist are hallmarks of the Kashmir style."

The Roman Space Telescope was canceled five times in presidents' budget requests - twice during the Obama era and three times in the first Trump administration. Each time, Congress elected to save the mission.

Scoop: For nearly a year, NSF has struggled to make new grants. Now we know that it will not catch up. In fact, NSF will award just 6,100 new grants—a 30% y/o/y decline, itself down from a previous avg. of 11,000+. In fact, the last time NSF awarded so few grants was in the early '80s.
