·     No glyphs given in K&H (but the meaning sibik/sabak = “ink” is given, just no glyph).

·     Zender-TRGiCMW.p13.pdfp8 has a passing mention to SIBIK:

o “…a small, winged supernatural who elsewhere appears as a personified tree (TE’), and as the patron of the month Pax (SIBIK-TE’)” as portrayed on Sculptured Throne Back held in the Museo Amparo (a.k.a. the Sáenz Throne, after its first owner).

o Sim: the SIBIK-glyph appears on the Pax God’s nose, somewhat like a tag to the iconography.

·     K&L.p30.#2.3: this is a representation of a split shell, with ink in it (black part).

·     For PAL TI Sarcophagus Lid Edge glyph-block #14 Guenter-TKJP.p57 reads KUCH? instead of SIBIK but this reading is now considered outdated.

·     Iconographic origin: a medium-sized seashell, sawn open to reveal inner chambers which can be filled with ink (lost reference, paper devoted to a shell).

·     Features – this glyph is subject to quite extreme variation:

o Top: (optional) “KUCH”: A KAWAK flanked by three touching dots in a triangular formation on each side (such a component is also present at the top of t’o and k’o).

o Bottom – boulder always divided into 2 parts by a horizontal line (optionally bold):

§ Top: (often) 3 non-touching dots in a triangular formation, pointing up = “upside-down face” – but large variation in this: it can also be empty, or have a single or two non-touching dots). Often empty if the optional “KUCH” is present, as this is sufficient to identify the glyph.

§ Bottom – divided into 2 parts by a straight vertical band:

·       (Often) (slightly) curved L-shaped band from ceiling to one side of the vertical band.

·       Two touching dots sticking out of the straight vertical band, on the side of the vertical band opposite to the curved L-shaped band (when L-shaped band is missing, the two touching dots can occur alone).

·       (Optionally) three non-touching dots in a triangular formation, on the side opposite to the two touching dots (i.e. they can replace the L-shaped band) – the dots can be optionally dark (representing the ink?).

·       (Optionally) the side with the two touching dots can be dark (representing yet more the ink?).

o There is a head variant which has many of the distinctive characteristics from the more abstract variant infixed into an anthropomorphic head.

·     IB = “bean” and SIBIK = “ink/soot” have many characteristics in common (see also IB):

o They both have an optional top part – “left and right protected scrolls” in the case of IB and “KUCH” in the case of SIBIK.

o The non-optional parts of the two share many characteristic infixed elements:

§ The 3-dot triangle pointing up, of non-touching dots.

§ The vertical band with two touching dots on one side, resembling a TE’-like wood property marker.

§ An L-shaped element on the other side of the vertical band.

·     Distinguishing between IB and SIBIK:

o IB shares its optional “protected scrolls” top element with many other glyphs, and SIBIK shares its optional “KUCH” top element with t’o and one variant of k’o.

o The most drastically reduced form – T709 – could really be either IB or SIBIK, as it has only the distinguishing elements which are common to both.

o Context and the presence of one of their respective optional top elements helps to determine which of the two glyphs is present in an inscription.

o The presence of three non-touching darkened (cross-hatched or fully filled black) dots in a triangular formation – in the lower half of the glyph – is a distinctive characteristic which immediately identifies SIBIK.
