petrean , also: petraean

The Petrean Society is the alumni/alumnae association of individuals involved in the Peterhouse Boys' and Peterhouse Girls' schools.

In 1839 he opened the Petrean fellowships at Exeter College to natives of Cheshire by conveying a small incorporeal hereditament to Lord Petre for that purpose.

The Sylloge centulensis, from an eighth- or ninth-century manuscript of the monastery of Corvey, compiled on a trip from Rome to Spoleto to Ravenna, records "what we might term Petrean poetry", a style lying between classical and medieval forms.
