Rare Antique Copper Persian Urn

I have a RARE ANTIQUE COPPER URN W/ LID and STAND.  Some generous person donated this unique piece to an Animal Rescue Resale Thrift Shop and I purchased this vessel there.  I haven’t noticed any markings on the bottom or inside.  However, it has a lot of patina (which may be covering it).  The item has inscriptions intricately etched into the body and the lid.  I was told the writings may be Persian.  The copper lid appears to have a brass knob.  The height w/o the stand is 15.5”.  The height including the stand is 18.5”.  The width is 13” and the depth is 10”.  All measurements are approximate.  I have unsuccessfully scoured the internet trying to find a similar item. 

Thank you in advance for your time and expert opinion/estimate.
