So,looking for a good weather and sun I found this picture.Mihai Cantacuzino(Michael Kantakouzenos),a prince from Byzantine Emperors' family was one of the high officials of the Lord of Wallachia.He was high steward(stolnic) and spatharus(cavalry commander and sword of the lord bearer).
In 1690 he visited,with her mother,The Holy Land and St.Catherine Monastery from Sinai Mountain.At that time these territories were under the Ottomans.For Wallachia were hard times- Russia on its right and Austria,which took Belgrade several times,on the left-. Michael being a very rich man, from lord's family, his dignities were"on paper" only,like today. That could be an explanation for his walk,far from the country,in those conditions.
