So, one thing is clear: the etching was made by a Farsi-speaking person. Whether he was an itinerant master from Iran or a Persianized Afghani is unclear. In any case, it may explain the human figure and ,- perhaps,- the date of 1850 in Persian calendar Jalali.
I beg to differ! Nothing is clear. The one who made the etching could have been simply copying it 1:1 from somewhere else.
