Jane Akshar has done one of her much appreciated write ups of a lecture at the Mummification Museum in Luxor, with Francisco Tiradritti talking about the work in the Tomb of Hawra.
The team started work at the tomb of Harwa in 1996 although a survey had been done a year earlier. Harwa was a very important official, steward of the God’s wife of Amun or Divine Votaress and there are 8 known statues of him (see the website http://www.harwa.it/harwa.php?action=reset also for a life see http://www.harwa.it/vecchisiti/sito99/harwlife.htm ) and they are in different styles the ones in the Cairo Museum and 1 in BM are Old Kingdom, the block statues are New Kingdom and there is a shrine that is Middle King. This is because the 15th Dynasty was part of the great Renaissance of Egypt. Although all periods had copied previous styles the Nubian Kings specialised in this by with a Nubian twist.
The rest of the write up is on Jane's blog.
