kitharas

In wall paintings of the eighteenth dynasty we see flutes, double flutes, and harps of all sizes, from the small one carried in the hand, to the great harps, almost seven feet high, with twenty-one strings; the never-failing sistrum (a kind of rattle); kitharas, the ancestors of our modern guitars; lutes and lyres, the very first in the line of instruments culminating in the modern piano.
