¶ Sum situs hic brevior. longumque remetior ensem.
Cuspide sepe minor. illuc tamen inde rerutor(?).

¶ Laevus e^:go situs ipse vocor / Veraeque fenestrae.
Sic celer in dextra velut hac sum nempe sinistra.

¶ Protrahor in terram situs en caudatus. et ante /
Postque ago persaepe traiectis ictibus ictus.

¶ Nominor a cunctis certe situs ipse bicornis.
Nec pete quam falsus / quam sim nunc callidus in te

Or "saepe" (often), which may be more likely than "sepe" (hedge or defensive barrier)

More likely laevus than levus

the last word seems faded compared to the rest

Added later: "scilicet ego."
