I’ve started to look at a new Super Caster holder design for Giant Caster matrices. Here is the next concern: with respect to head bearing and a base line on the matrix, Giant Caster mats appear to align to a constant base line, and English matrices appear to align close to the centre line of the matrix, see the above picture of English alignment mats arranged in ascending point size, with the head bearing to the right, foot to the left.
I commented about this situation in my Super Caster book:
“The centre line of an English Monotype matrix holder for any size appears to be designed to locate down the middle of the type face. Any variance in thermal expansion during operation was effectively cut in half, i.e. half the expansion was above the centre line of the face on the type body and half below, call it centre alignment.”
This situation could use more mathematical analysis, I now think the centre line might be down the middle of the type body, not the middle of the face, based on visually lining up insets. The only reason I can guess for dong it this way is slightly greater accuracy, which was always the top theme at English Monotype.
It will be interesting to see how this affects the final matrix holder design; theoretically, with the constant base line close to the bottom (nick side) of the mat, the large Giant Caster mats will stay away from the Type Carrier.

This is an English Super Caster matrix holder modified by the factory to hold Ludlow matrices. Photo by Jason Dewinetz.
The seal on the left dates from the 12th century, and the other dates from the 13th century. They were found in an old box during an inventory of artifacts at Lincoln Cathedral. Their discovery and verification was announced in September 2018. At the time this photo was taken, they were being displayed in the Treasury in Lincoln Cathedral (on the north side of St. Hugh's Choir).
The following is quoted extensively from the online journal "Museum Crush," article "The 12th century medieval seal matrix found in a cathedral box" (Richard Moss, 20 September 2018):
"An overlooked box in a cathedral storeroom has yielded a...rare 12th century seal matrix used by the medieval Dean and Chapter to officially give documents a seal of approval.
"Dating from the time when the cathedral was under construction – work began in 1092 and continued in several phases throughout the medieval period – the silver seal with a classic pointed oval ecclesiastical design, is one of only a handful of comparable silver institutional matrices to have survived. Another like it, but from the 13th century is the Chichester matrix at the British Museum.
"The engraved metal die or ‘matrix’ would have been pressed into a material such as wax, clay or even paper to authenticate a document in much the same way that we use signatures today. It would also have been used to literally seal documents and transactions officially drawn up by the cathedral throughout the Norman period and beyond.
"The discovery was made during an audit of the Cathedral’s extensive collections as part of an ongoing National Lottery funded project to improve the visitor experience, and was found in a box of previously uncatalogued replicas. It was believed to be Victorian in date until a closer look revealed the truth.
"Experts, including academics from the University of East Anglia and the British Museum, agree that the matrix dates from the early medieval period.
"The seal depicts the patron saint of Lincoln Cathedral, the Virgin Mary, who is shown crowned and seated on a throne, holding the infant Christ in her lap. In her left hand she holds a flowering rod topped by a fleur-de-lis.
"Alongside the Chapter Seal, [another rare matrix was] also discovered in the same box, [a]...13th century seal matrix of the Vicars Choral..."
another method of creating a matrix by electro-depsiting a copper “flower” on the face of type. This was how duplicate matrices could be fabricated if punches or matrices were lost or damaged, and how type was pirated by competing foundries.
Erice est une ville située au nord-ouest de la Sicile dans la province de Trapani (12 km de Trapani), sur le mont San Giuliano, à 756 m d'altitude. L'occupation du mont Éryx remonte au Néolithique et à l'Âge du bronze. Le site est une des principales cités des Élymes.
La cité est conquise par les Carthaginois au VIe ou Ve siècle. Ils élèvent une muraille cyclopéenne sur un soubassement mégalithique élyme, pour se défendre des Syracusains.
Phylogenomic overview in Gegenees.Both heat-plots of the similarity matrices and trees created from the same data are shown. A. A Gegenees heat-plot over a set of Bacillus strains that had previously been analyzed by MLST [17]. The heat-plot is based on a fragmented alignment using BLASTN made with settings 200/100. The cutoff threshold for non-conserved material was 30%. A dendrogram was produced in SplitsTree 4 (using neighbor joining method) made from a Nexus file exported from Gegenees. B. cytotoxicus was set as outgroup. The clustering is very similar to previously published trees. The scale bar represents a 1% difference in average BLASTN score similarity. B. A Gegenees heat-plot over a set of yeast genomes that has been analyzed before with different phylogenomic methods. These genomes are more distant from each other and a BLASTN comparison does not resolve them well (data not shown). A fragmented alignment in TBLASTX mode was performed with settings 200/200. The cutoff threshold for non-conserved material was 20%. A dendrogram was produced in SplitsTree 4 (using neighbor joining method) made from a distance matrix Nexus file exported from Gegenees. Y. lipolytica was set as outgroup. The clustering here is also very similar to the previously published trees [2]. The scale bar represents a 10% difference in average TBLASTX score similarity.
