And seven years further skill admit

To raise them to their perfect height.

When nine such periods have passed,

His powers, though milder grown, still last;

When God has granted ten times seven,

The aged man prepares for heaven.

XXXVI. (105) Solon therefore thus computes the life of man by the aforesaid ten periods of seven years. But Hippocrates the physician says that there are Seven{7}{it is hardly necessary to remind the reader of the description of the seven ages of man in Shakespeare. As You Like It, Act II. sc. 7.} ages of man, infancy, childhood, boyhood, youth, manhood, middle age, old age; and that these too, are measured by periods of seven, though not in the same order. And he speaks thus; “In the nature of man there are seven seasons, which men call ages; infancy, childhood, boyhood, and the rest. He is an infant till he reaches his seventh year, the age of the shedding of his teeth. He is a child till he arrives at the age of puberty, which takes place in fourteen years. He is a boy till his beard begins to grow, and that time is the end of a third period of seven years. He is a youth till the completion of the growth of his whole body, which coincides with the fourth seven years. Then he is a man till he reaches his forty-ninth year, or seven times seven periods. He is a middle aged man till he is fifty-six, or eight times seven years old; and after that he is an old man.
