 Although the leaves are not as refined and do not evince the same technical ability as those of Hand G, they contain realistic and unflinching depictions of human distress and a number of iconographic and stylistic innovations that suggest they are copies of prototypes by Jan. Charles Sterling notes similarities between Hand H and passages in the New York "Crucifixion and Last Judgement diptych" miniature, a work for which completion dates as wide as 1420-1438 have been suggested, and which is known to have been finished by members of Jan's workshop.He notes the influence on van Eyck's successor in Bruges, Petrus Christus, who is known to have served as a journeyman in Jan's studio from the early 1430s.He suggests that the "Agony in the Garden" in particular was influential on painters in the 1430s, especially on southern German painters such as Hans Multscher and Lodewijck Allynckbrood who produced a number of works clearly indebted to Hand H.
Hands I–K are all working in a similar Eyckian style, perhaps following underdrawing or sketches by Hand G, and are usually seen as members of Jan's workshop, although many now think work continued after Jan's death, which was by 1441 (Hubert had died in 1426).
