Experts have translated this document (as with Facsimile #1) with completely different meanings than that of Joseph Smith.
The figure represented by Facsimile #2 is a common artifact known as a hypocephalus; there have been more than 100 of these found, each quite similar to the other.
Hypocephali are placed under the head or feet of the mummified person to assist them in remembering what to say and do in relation to the trials they would face after death.
Facsimile #2 was damaged (as was #1) when Joseph Smith received it. He took it upon himself to ‘fill in’ missing areas as he was inspired to do so.
