I am glad you posted it. I had made a copy for my daughter-in-law (a doctor), and judged, perhaps wrong, that Mudcatters wouldn't be interested. I didn't know Hood's poetry; it is light and amusing. Mary's Ghost and Ghost are two more posted at the same site.

'Pompey's Ghost' is mentioned in Lucan, "De bello civili," appearing to Sextilus in Sicily, fortelling Caesar's murder. I haven't looked for a poem about this Pompey (Pompey and Caesar at one time rival commanders, at the time Caesar crossed the Rubicon.

Definitely not Hood's poem, but one about the Roman.
