Abandoning the expansionist policies of his predecessor Trajan, Hadrian established a policy of defence and consolidation during which Hadrian's Wall in Britain was constructed. Hadrian traveled more than any other emperor, visiting many, many provinces and towns, often ordering grandiose building programs to improve the infrastructure and quality of life in those regions.
Hadrian, 11 August 117 - 10 July 138 A.D., Roman Provincial Egypt
The Greek numeral sixteen (IV) above Nilus refers to what was considered the ideal height of the annual Nile flood, sixteen cubits. Less could mean drought or famine. Much more could mean dangerous flooding. Herodotus gives 24 cubits as the highest recorded rise of the Nile. The lowest Nile on record before the river was dammed was about 13 cubits in 966 A.D.
