Task: Question Answering
Input (English): Passage: Because of shared characteristics, including common use of horror vacui, similar spatial approaches and use of depth, as well as similar hinges and methods of construction, Leeuwenberg has suggested that production of a number of the miniatures was overseen by a single master named Adam Dircksz, Dircksz was first identified through a signature on a prayer nut now in the Statens Museum Copenhagen, reading "Adam Theodrici me fecit" (Adam Dircksz has made me). The Latin name "Adam Theodrici" may be translated into English as "Adam of Theodoric", but art historians usually use the Dutch version of his name, Adam Dircksz. Although it was rare in the 16th century for artists to sign a work, when done, it usually took the "me fecit" (made me) form, in effect of making the object speak.Almost nothing is known about Dircksz except that the works were produced c. 1500–30. The signature may indicate that he was a woodcutter, sculptor, medallist, or just simply the patron. Dircksz is thought to have been active between 1500 and 1530, and responsible for some sixty of the surviving examples. He may have led a workshop in the southern Netherlands, given that Flemish inscriptions appear on some of the carvings. Alternatively, it was located more northerly, possibly in the north of Brabant or at Delft in Holland. In any case, apart from Henry VIII and Catherine, all of the original owners come from the Netherlands.Regardless of the number of works that Dircksz or his workshop can be attributed with, art historians often debate what the artistic and technical precedents for the miniatures might be. Scholten observes how, to a large extent, it seems "as if this exquisite sculpture was born ex nihilo around 1500", but points out that "giant strides are rarely made in art history", pointing to affinities with silversmith's art, especially the miniature architectural elements often found in ecclesiastical silver and ornaments. 
Question: What is the name of the person that points out "giant strides are rarely made in art history"?
Output (English): Scholten.
