[7arg] That the leaves of the olive tree turn over at the summer and the winter solstice, and that the lyre at that same season produces sounds from other strings than those that are struck.IT is commonly both written and believed that at the winter and the summer solstice the leaves of olive trees turn over, and that the side which had been underneath and hidden becomes uppermost and is exposed to sight and to the sun. And 1 myself was led to test this statement more than once, and found it to be almost exactly true. But about the lyre there is an assertion that is less often made and is even more remarkable. And this both other learned men and also Suetonius Tranquillus, in the first book of his History of the Games, 1 [p. 175] declare to have been fully investigated and to be generally accepted; namely, that when some strings of the lyre are struck with the fingers at the time of the winter solstice, other strings give out sound.
