The prints span an eleven year period ostensibly to record a whole solar or sunspot cycle. That the purpose of the exercise may have been to investigate the supposed effect of planetary configuration on the abundance of solar spots is indicated by the presence of charts of planetary positions pasted on the verso of the mount boards and corresponding in date precisely to the prints.
