Simple Mortise & Tenon
This is the most basic and likely the first closed mortise connection.
A version of this joint, in stone, and without a peg, can be seen
in Stonehenge. It is beyond a doubt, the best connection for a vertical
post to support a horizontal beam.
An average frame, 1400 -1800 sq ft, would typically have 18 - 25 of these joints.
