Slide #19/ 1997 from "DNA Studies" series (detail)/ drawing, ink on paper/ 21"x34" This and the next piece result from a commission requiring DNA for theme. The intent was to create a series of time pieces evoking the DNA story, resulting in research on strands, ribbons, and helices and imposing a formal constraint.

Slide #20/ 1997 from "DNA Studies" series (detail)/ drawing, ink on paper/ 19"x23" This is another variation looking to satisfy the theme of the DNA commission.

Slide #21/ 1998 III from "Inferno" series/ iris print/ 19"x26" A very dark illustration for a page of Dante's Divine Comedy (Inf. III, 9) "All hope abandon, ye who enter in!". This print has been reviewed in Art on Paper (March'99) — see review.

Slide #22/ 1998 "Nowhere, Fog, November"/ iris print/ 19"x26" One of three 'Nowhere' pieces, studies based on the composition of several levels of texture rendered in different inks and background colors.

Slide #23/ 1998 "Tessiture Taciturne"/ iris print/ 19"x26" This is built over a favorite quiet and simple motif, to be enriched by a sumptuous and fine texture (the subtle nuances hardly showing on slides).

Slide #24/ 1998 "Tessiture Taciturne" (detail)/ iris print/ 19"x26" A detail of the previous piece shows the astounding precision and complexity of the line work: a means and not an end, but the result of years of experimentation and now well under control.

Slide #25/ 1999 from "Hundred Views" series (detail)/ iris print/ 19"x19" This is one among the "Hundred Views of a Polyline", a series built on a widened representation and interpretation of lines in the context of a classic theme by Max Bill. This series is an on-going research and has proven being very fertile, revealing many surprisingly beautiful possibilities arising from latent mathematical orders at all scales.

Slide #26/ 1999 "Ochre on Raw Sienna" / ink on paper/ 14"x14" This is a piece with a fine layering of colors similar to painters' glacis, using two very close colors to render this variation of a favorite theme.
