Decipherment of ancient Egyptian scripts

Decipherment of ancient Egyptian scripts.
The decipherment of ancient Egyptian scripts was accomplished in the early nineteenth century by several European scholars, especially Jean-François Champollion (pictured) and Thomas Young. Egyptian writing, which included the hieroglyphic, hieratic and demotic scripts, ceased to be understood in the fourth and fifth centuries AD. Afterwards, it was believed that Egyptian scripts were exclusively ideographic, representing ideas, rather than phonetic, representing sounds. The Rosetta Stone, discovered in 1799, bore a parallel text in hieroglyphic, demotic and Greek, but deciphering the Egyptian text through its Greek translation proved difficult. Young, building on the work of Antoine-Isaac Silvestre de Sacy and Johan David Åkerblad, identified several phonetic signs in demotic. In the early 1820s Champollion realised the hieroglyphic script had both phonetic and ideographic elements. He identified the meanings of most phonetic hieroglyphs and established much of the grammar and vocabulary of ancient Egyptian.

Suillus luteus

Suillus luteus.
Suillus luteus is a bolete fungus common in its native Eurasia and widely introduced elsewhere. English names such as "slippery jack" refer to the brown cap, which is slimy in wet conditions. The mushrooms are edible, though not highly regarded, and are often eaten in soups, stews or fried dishes. The fungus grows in coniferous forests in its native range, and pine plantations where introduced. It forms symbiotic associations with living trees by enveloping the underground roots. The fungus produces spore-bearing mushrooms above ground in summer and autumn. The cap often has a distinctive conical shape before flattening with age. Instead of gills, the underside of the cap has pores with tubes extending downward that allow mature spores to escape. The pore surface is yellow, and covered by a membranous partial veil when young. The stalk is pale with small dots near the top. It bears a distinctive ring that is tinged brown to violet on the underside.

Muhammad II of Granada

Muhammad II of Granada.
Muhammad II was the Nasrid ruler of the Emirate of Granada in Al-Andalus on the Iberian Peninsula from 1273 until his death in 1302. Succeeding his father Muhammad I, he maintained Granada's independence in the face of its larger neighbours, the Christian kingdom of Castile and the Muslim Marinid state of Morocco. He added the Tower of the Ladies and the Tower of the Points to his father's palace and fortress complex, the Alhambra (pictured). To defend Granada against the Christians, he recruited soldiers from North Africa and organized them into the Volunteers of the Faith. He instituted the Nasrid royal protocol and the court chancery and increased the importance of the vizier in government. Muhammad II built a series of strongholds in strategic positions that remained for centuries as the backbone of Granadan border defences. He was known by the epithet al-Faqih, the canon lawyer, reflecting his education and his support for scholars and poets.
