© Science Museum / Science & Society Picture Library
An allegorical title page. On the left stands Destiny, 'whose governor is knowledge', holding a geometric compas and 'the sphere of Destiny', an armillary sphere. She is facing a blindfolded Fortune, 'whose ruler is ignorance', who holds 'the wheel of fortune' aloft. Between them stands the Castle of Knowledge, a trophy that only knowledge can attain. On its turrets are men with a quadrant and an astrolabe. Illustration from 'The castle of knowledge' by Robert Record (1510?-1558), published in London in 1556.
