Surgath
First documented attestation
In the De Secretis manuscripts (Clavicula Salomonis de secretis, 17th c. — Dresden N.91, Rps 3352 II, Venice b.93) as «Surgath», with its power and its drawn character. This is the stratum preceding the printed Verum.
Power in the manuscript (De Secretis, Latin)
«Surgath, ad aperiendas clausuras est Idoneus.»

This same character is also drawn (in red and green ink) in L'Art Magique (Wellcome MS.983, ~1709), the French witness closest to the printed Verum — public domain.
The character in the manuscript (colour)
How it is invoked (De Secretis, 17th c.)
To open closures admit the Arcanum: upon a lodestone trace the Cross of Saint Andrew (or two crossed magic wands), draw a circle with an inscribed square, and in each lunula place the characters Surgath, Menail, Remicheal, Ragadamor; with iron filings; placed before the locks, they will open without doubt.

How it is invoked (Grimorium Verum, 18th c.)
The printed Verum also includes him in the nail rite with Guland and Morail: take a nail from an old coffin, find a footprint, draw the three figures, fix the nail in the middle, and pronounce the stated formula; to remove the evil, the nail must be taken out and the characters effaced with the other hand.
