As previously mentioned there is no doubt that the 'forked cross' or cross fourchee appeared encircled as a known blade marking in 1590, but who actually used it remains unknown...it was likely used by a number of makers on blades as was the case with many of these marks. The use of crosses on blades, particularly along with names and invocations was well established with the Vlfberht, Ingelrii and Gicelin blades of Frankish origin from mid 10th to mid 11th centuries, usually encapsulating the words or names. These were typically Greek crosses (potent) with serif type arm ends also known as the kruckenkruez (crutch cross) in later times (Jerusalem cross by the time of the crusades).

In the 6th and 7th centuries crosses were placed on scabbards for the protection of the sword, blessing it and guarding it in battle (Ellis-Davidson, 1962, p.93). It is known that earlier, various symbols including crosses were inlaid in blades usually in gold or brass (latten).

It seems that the nature of the cross appearing on this blade is distinguished by the forked ends as discussed, and that while crosses have appeared on blades over many centuries, this form is somewhat distinctive. These forked ends are seen on cross & orb marks on German blades assessed by Sir James Mann (Wallace Coll. A524, p.269) as 16th century. In previous discussions it has been noted that the forked end cross fourchee is seen on several examples of swords of justice of presumably 16th to 17th century. These are attributed typically to the Vehmic courts or tribunals of Westphalian regions primarily and the cross fourchee occurs between the letters 'S' configured as S+S .
(Sacrificum Sanctum). These courts were well in place by the 15th century having been established in Charlemagnes time.

While this type of cross cannot be firmly attributed to these secretive groups it is interesting to note the use of this type cross. The form can also be associated as previously mentioned to sacredotal instances concerning clerical vestments, and the use of the cross fourchee (or moline) on the chausuble worn. It is interesting that the 'pall cross' or Y shaped cross is seen in paintings of the Crucifixion in the 13th century and later. This perhaps may have been considered in the use of these forked terminals on the cross, of course along with other possibilities.

Whatever the case, it would seem quite likely that this type of cross inlaid in this manner predates the 1590 estimate as discussed in markings references.
Regarding the cross and orb, these date far into antiquity and were well in use in variation from Byzantine times (used even in Egypt by the Coptic Christians) and in Germany in the 15th century in printers guild marks, in Venice on blades in examples c.1520 and 1560 (Boccia & Coelho, 1975).
Interestingly this device was used in the badge of the Carthusian Order in Cologne c. 1084. Cologne of course was the precedent of Solingen in arms production and it seems possible this could be significant in its use by these makers, but clearly speculatively speaking.

In summary, I do not believe that earlier date for this blade than 1590 is compromised at all by the cited markings references shown. Typically these authors simply lifted the material from previous authors thus various entries cannot necessarily be considered supportive of each other. What would be excellent would be finding similar marking on well provenanced example which is dated.
