As mentioned in this question, this commentary mentions one "Theophylact" who was apparently a contemporary of Athanasius. Wikipedia only provides a list of figures who lived well past Athanasius's time, and in my research, I've only found information about the people on that list. Here's the quote from that commentary:
Some (for instance, Theophylact) understand this "as it were" to signify that the expression, "drops of blood," was simply parabolic; but it is far better to understand the words in their literal sense, as our Church does when it prays, "By thine agony and bloody sweat." Athanasius even goes so far as to pronounce a ban upon those who deny this sweat of blood.
