“At length they saw a man coming (namely Paul), of a low stature, bald (or shaved) on the head, crooked thighs, handsome legs, hollow-eyed; had a crooked nose; full of grace; for sometimes he appeared as a man, sometimes he had the countenance of an angel. And Paul saw Onesiphorus, and was glad.”
–from the apocryphal “Acts of Paul and Thecla” 1:7
