[1] The headword is present active participle, masculine nominative singular, of e)nth/kw (cf. epsilon 1446, epsilon 1464, epsilon 1473); presumably extracted from the quotation given.
[2] Adler notes the suggestion by Jonathan Toup (1713-1785) that this unidentifiable quotation concerns 'Crassus or Manius'. This 'Crassus' is the super-rich M. Licinius Crassus, who in fact died in battle in Parthia, before this gruesome way of killing him could be put into effect; nevertheless, late sources claim that this was done to him post mortem. As to 'Manius', this is M.' Aquillius (cos. 101 BCE, with Marius); he was indeed killed, in 88, by King Mithradates VI of Pontus (mu 1044), using this method (Appian and other sources in Broughton MRR II.43), on the grounds of actions, prompted by avarice, that had provoked the First Mithradatic War.
