• Constantinople was full of inventors and craftsmen. The "philosopher" Leo of Thessalonika made for the Emperor Theophilos (829–42) a golden tree, the branches of which carried artificial birds which flapped their wings and sang, a model lion which moved and roared, and a bejewelled clockwork lady who walked. These mechanical toys continued the tradition represented in the treatise of Heron of Alexandria (c. AD 125), which was well-known to the Byzantines.
