entrail

And in the thickest covert of that shade / There was a pleasant arbour, not by art / But of the trees' own inclination made, / With wanton ivy twine entrailed athwart, / And eglantine and caprifole among, / Fashioned above within their inmost part / That neither Phoebus' beams could through them throng / Nor AEolus' sharp blast could work them any wrong.

A cross entrailed.
