In old mythology we read
My whole was served by Ganymede.
[19]
AN old philosopher was my last,
And his wife was my first in the distant past.
Select two sticks that are smooth and straight,
Lay them with care and precision great,
One north and south, one east and west,
They are my whole, it must be confessed.
[20]
TO the grandest of monarchs that ever was seen
My first was presented by Sheba’s fair queen.
Far, far away back in the ages long past,
According to science, the earth was my last.
My whole, on a rock, is reputed to be
A danger encountered by sailors at sea.
