Now Tom,
Are you putting me on? The only words that were familiar to me in this
entire treatise is "horse" and "fat". While reading, I was trying very hard
to comprehend but a little nagging voice kept poking me in the side
saying"he's got to be toying with you. He can't really expect this to make
sense to you or he would have written it in English, or Latin as the second
best choice. But, no, he has chosen Greek.
Pat
