The flame of thought which brings fulfilment

Dyma fanyldeb o gerflun yn y Prif Adeilad Prifysgol Caerdydd. Dw i'n meddwl taw llywiwr yw'r dyn. O dan y cerflun yw arysgrif Groeg 'Phrontidos telesphoron selas' ('Mae'r fflam meddwl sy'n dod â chyflawniad').

This is a detail of a carving in the Main Building of Cardiff University. I think that the man is a navigator. Under the carving is a Greek inscription 'Phrontidos telesphoron selas' ('The flame of thought which brings fulfilment.').
