The following autumn he attended Trinity College, Cambridge, where he met and formed a close friendship with the younger John Edleston. About his "protégé" he wrote, "He has been my almost constant associate since October, 1805, when I entered Trinity College. His voice first attracted my attention, his countenance fixed it, and his manners attached me to him for ever." In his memory Byron composed Thyrza, a series of elegies.
In later years he described the affair as "a violent, though pure love and passion". This statement, however, needs to be read in the context of hardening public attitudes toward homosexuality in England, and the severe sanctions (including public hanging) against convicted or even suspected offenders. The liaison, on the other hand, may well have been 'pure' out of respect for Edleston's innocence, in contrast to the (probably) more sexually overt relations experienced at Harrow School.
