A variant spelling of 'ashoka' or a historical term related to South Asian rulers or Buddhist monuments.
This appears to be an alternate or variant transliteration of Sanskrit 'Asoka' (also spelled 'Ashoka'), the name of the great Mauryan emperor of India (268-232 BCE). The spelling varies based on transliteration conventions from Indic scripts.
The word 'asok' shows how English struggled with transliterating Sanskrit—different scholars would spell the same name different ways, creating ghost-variants that appear in old texts as 'Asok,' 'Ashok,' 'Asoka,' all referring to the same historical figure.
