The poetry and art of Galileo Galilei
Bill Dennison ·'Scientists who made a difference' series
This blog accompanying the biographical sketch of Galileo Galilei looks at a selection of his writing as poetry and a selection of his scientific sketches as art. The ‘Poetry’ uses Galileo's exact words (translated into English) in prose form, using the title ‘The Greatest Astonishment' to focus on the cadence and word choice. The ‘Art’ uses a multiple panel illustration that Galileo used the describe the phases of the moon that he was able to observe with a telescope that he constructed. It is worth noting that Galileo spent a couple of years at the Academy of the Arts and Drawing in Florence. He really had an artistic 'eye' and an ability to write eloquently. Both the ‘Poetry’ and ‘Art’ of Galileo are found in his book Sidereus Nuncious (Starry Messenger), published in 1610.
The greatest astonishment
By Galileo Galilei
In the present small treatise
I set forth some matters
Of great interest
For all observers
Of natural phenomena
To look at
And consider.
They are of great interest,
I think,
First, from their intrinsic excellence;
Second, from their absolute novelty,
And lastly,
Also on account of the instrument
By aid of which
They have been presented
To my apprehension.
But that which will excite
The greatest astonishment by far,
And which indeed especially moved me
To call the attention
Of all astronomers and philosophers,
Is this,
namely,
That I have discovered
Four planets,
Neither known
Nor observed
By any one of the astronomers
Before my time,
Which have their orbits
Round a certain bright star,
One of these previously known,
Like Venus and Mercury round the sun,
And are sometimes in front of it,
Sometimes behind it,
Though they never depart from it
Beyond certain limits.
All which facts
Were discovered and observed
A few days ago
By the help of a telescope
Devised by me,
Through God's grace
First enlightening my mind.
