Left: A Stern-Looking Lady Liberty; Right: Pancho Villa Headline
The headline reads “Villa Captures Carranza Garrison, …” referring to Francisco Villa (1878 – 1923), nicknamed Pancho Villa, a Mexican Revolutionary general, and Venustiano Carranza de la Garza (1859 – 1920), a leader of the Mexican Revolution who became President of Mexico. It’s not clear which of the many skirmishes with Carranza the headline refers to.
The designers seem to want us to read the mural as a very compact timeline from left to right starting with the Maya, moving to the Aztecs, to an eagle grasping a snake (as on the Mexican flag), to something in the middle no longer visible, to the Mexican Revolution, and finally to a very stern Lady Liberty.

Left: Ficus Spelled in its Small Brown Berries; Right: Ficus microcarpa, Indian Laurel, Branches
In this installment of Binomen Art, we’ll spend a little time with Ficus microcarpa, known by many names, but we always just call it, Indian Laurel. This particular specimen is over 30 years old and it is massive. As I was listening to the fruits (figs, right?) falling from the tree and rolling down the roof, the idea hatched to pay a small ode to this majestic tree. We spelled out the generic name Ficus with the brown fruits, on the base of the tree. The fruits on the tree are small, yellowish-green, rounded, and at the end of branches. The specific epithet, microcarpa, refers to the small fruit, which is claimed to be not edible.
What’s interesting, is that many pictures of F. microcarpa that you might find, show “aerial roots” - technically adventitious prop roots – growing down from the branches to the ground. However, you don’t see prop roots in the Indian Laurels in Southern California, like this one in the Imperial Valley. Likely, this is specific variety that doesn’t have that behavior, or the conditions are not right, being too dry.
The generic name, Ficus, according to the Quattrocchi is from the:
Latin ficus, i, and ficus, us for a fig-tree, Ficus carica L. or the edible fruit of the fig-tree, Greek sykon “fig”, Akkadian piqu or siqu “narrow”, piaqum, siaqum “to be narrow”…
If Quattrocchi is reaching back to Akkadian, you know this tree has roots.Left: F. microcarpa Berries on the Branch; Right: Ficus in Berries

This statue in Brawley California represents the American cowboy Casey Tibbs riding a bucking bronc. This is one of two statues celebrating Brawley’s signature event, the Brawley Cattle Call Rodeo. These photos are of the statue located at Park Plaza downtown (here). Read more about them here: Brawley Cattle Call horse statues get a make over.
Notice the small bucking bronc that caps the street sign post.

To date we’ve had special quesadillas – that deep-fried tortilla, cheese filled taste sensation – at Celia’s (see Special Quesadilla) and Camacho’s (see Camacho’s Place Mexican Restaurant in El Centro California). This time around we tried it again at Celia’s and at Nana Dora’s in Brawley. Both were very good.Celia’s (El Centro, California) Special Quesadilla (Left) and Sign (Right)

Left: A Beautiful Web of the K. arizonica? Right: K. arizonica at night.
For years we knew this spider as only a “Phyllis Paddit” spider. It creates webs all over the Imperial Valley ranch where we stay. The webs are sticky and hard to remove. A type of flycatcher uses the webs to construct resilient nests. Despite all of this, I’d never seen one of these spiders. So I investigated.
The investigation trail went something like this:
- I happened to come across the web site Spiders of the Californias where I was contemplating the type of spider web I was seeing. Answer: funnel weaver.
- Okay, funnel weaver, but I needed more. So I started searching for spider web imagery, in particular, images of funnel weaver (family Agelenidae) webs. I happened to come across an image that looked very similar to the webs I was seeing. The caption of the photo was “Agelenidae or Filistata”.
- Suddenly it occurred to me that maybe there was an error in the transmission of the name, a classic case of Chinese whispers or the telephone game. The genus Filstata of spiders are called the filistatid. Sounds like Phyllis Paddit? Another case of funny naming is the “Swamp Molly” (see Swamp Mallet – Eucalyptus spathulata).
- The genus Kukulcania is another genus in the Filstatidae family – a family known as the crevice weavers. The genus is named for the Kukulcan, a Maya snake deity.
- Over time, I came to suspect the spider we call “Phyllis Paddit” is likely Kukulcania arizonica – the Arizona Black Hole Spider.
Some other interesting tidbits if this is indeed K. arizonica:
- These spiders are called cribellate spiders. In the Wikipedia entry for the related species, Kukulcania hibernalis (Southern house spider) there is this statement: “The southern house spider is a cribellate spider. That is, its spinnerets do not produce adhesive webbing. Instead, to capture prey the spider uses its legs to comb webbing across its cribellum, a spiked plate near the spinnerets. This combing action frays and tangles the strands, producing a fine, velcro-like netting that ensnares insect legs.”
- From the Wikipedia entry for Kukulcania arizonica: “This is a black spider with a velvety texture. It builds a silken tube in a crevice, often on the wall of a building, with silken threads radiating from the entrance. The female, around 13 mm in length (excluding legs), can live for several years.” Yup, radiating webs alright and about the right size.
- We only saw the spiders in the photos below at night. During the day, you would be hard-pressed to see them. Even at night, many of the specimens we approached retreated into their tunnels/crevices upon our approach.
There is more information about Kukulcania in the Field Guide to the Spiders of California and the Pacific Coast States.
As if to prove a point in terms of how much these spiders permeate the outdoors and indoors around here, we went to remove a book on insects from a shelf and out came a K. arizonica. Kulcania is not listed in the book, The Common Insects of North America, of course, because it isn’t an insect!
A quick visit to the Imperial Valley (and the sun) to escape the Seattle grey for a few days. At the end of the driveway where we stay, there are several Eucalyptus spathulata, commonly called Swamp Mallet. A mallet or marlock is a small tree-form or shrubby Eucalyptus found in Western Australia. (When we first heard of the tree, we heard it as “Swamp Molly” – as in a girl from the bayou.) At night the egrets come in to roost in these tree and it can smell quite rank underneath because of all the crawdads the birds eat.

I’ve been stewing over this post for some time because it has been hard for me to wrap my head around how sundials work. I think the modern age has rotted my brain.
We were back in Piemonte in the second half of May this year (2013), and this time we paid special attention to sundials. On a previous trip, Mondovì Sundials (Meridiane e Elementi di Gnomonica), we started to get interested in the sundials that we were seeing and how to read them. In this post, we show twenty sundials and try to delve into how they work. If you are easily confused or, looking for a complete sundial 101 explanation, this isn’t it. However, here are some good references I came across that you might consider:
- Shadows Pro – Sundial Overview – All roads in researching sundials on the Internet sooner or later lead to the Shadows Pro software. I’ve used the free (limited) version to create some images below.
- The Sundial Primer
- How to Make a Sundial, How Does a Sundial Work and Some Sundial History
- Sundials on the Internet – Includes lots of sundial resources, a bit busy and hard to navigate.
- Analemma – Learn more about the “figure-8” that you often see on sundials.
- Queen’s College Sundial – Contains a detailed explanation of the Queen’s College dial. Along the way you get a good explanation of how to read the time of year from a sundial that includes the path of sun (declination arcs).
- Timekeeping in the Ancient World: Sundials – Contains one of the best historically-motivated explanations of hyperbolae created on a sundial that trace the path of sun, and in particular, the summer solstice and winter solstice lines.
- The British Sundial Society Page - Has a good model of sundial with solstice lines and callouts to all the parts of a sundial.
- The Sundial and Geometry – An Introduction for the Classroom [pdf] by Lawrence E. Jones. This was one of the easiest introductions to read.
- Timelines – Walking Shadow Lines – Includes many images of sundials with annotations explaining how the dials are used. In particular, many sundials of the Prague Clementinum are shown.
- Sulla Cresta dell’Onda site has a page dedicated to sundials of Mondovì (Le meridiane di Mondovì).
Twenty Sundials in Piedmont (Piemonte)
The sundials featured in this post are not so much a reflection of towns that have many sundials, rather, the collection of sundials here reflect where we happened to be. That said, almost any town you happen to visit in Piemonte, if you look, will have a few sundials. (In my mind, Piemonte seems to have more sundials than other regions we have visited in Italy. I don’t have facts to back that up.)
All of the sundials (meridiana in Italian) we show here are vertical sundials. Vertical sundials are such that the sun can strike them, all or some part of the year. There can be northern facing sundials, which does make my head spin a little to think about.
Location: On the path to Santuario di Santa Lucia outside of Villanova Mondovi (location).
Orientation: Faces southeast. Notes: Contains four zodiac signs.
- Capricorn(♑) – the Goat, winter solstice.
- Aries (♈)– the Ram, spring equinox.
- Libra (♎) - the Scales, autumn equinox.
- Cancer (♋) – the Crab, summer solstice.
From The Sundial Primer site I found this interesting: “The names or signs of constellations are used in sundials instead of dates to specify declination lines. Because of the effects of precession over the period of 2,300 years since the constellations were first named, the signs of the zodiac have slipped by a whole sign, i.e. at the vernal equinox (defined as the first point of Aries), the sun is actually in the constellation Pisces.”
Location: Briaglia (location)
Orientation: North by northwest approximately.
Saying: Vesperis Aestivis ad Iucunda Convivia Silent Comit… [Pleasant evenng meals during the summer]
Notes: We ate a very nice dinner at Trattatoria Marsupino in this building. We go the pleasant meal part right.
The coordinates of Briaglia are 44.4000° N, 7.8833° E (44 24’ N, 7 53’E). This more or less northern facing dial is unusable from about early November to early February. This date range is what I simuated using using Shadows Pro, a useful program for ceating sundials and simulating shadows on the dial for times throughout the year. To create these images, I created a vertical sundial at the coordinates for Briaglia, with the sundial declination of approximately 158 degrees west. The red line is the summer solstice and the winter solstice is not visible because it’s not useful for this dial.
From the Shadows Pro help “The vertical declining sundial can represent all the states between a vertical direct east dial and a vertical direct west dial, as well as the vertical direct south (north) dial and the northern (southern) dial.” Also applicable to this dial and also from Shadows Pro “A sundial declining towards the North will be lit a litle during the morning and a little during the evening, but not during the day. In Winter, the sundial may not be lit at all.”
This dial, during a small part of the year, is lit during the morning. We did not show that here.
The picture was taken on 5/24/13 at 7:30 pm. I also simulated what the sun dial should be showing (removing daylight savings time) and I get about 6:30 pm. The gnomon shadow is hard to make out in the photo, but it’s just over VI.

Image 4: Approximately the first day in Winter when the sun starts hitting the dial.
Location: Carrù (location)
Notes: We were visiting someone in this building. Nearby is the famous “Bue Grasso di Carrú” sculpture. Italian hours (hours since last sunset) are shown.

Notes: Date taken 5/23/13 at 8:17 am (local time). The gnomon shadow is near 7, so the dial doesn’t account of daylight savings time. Because the shadow is below the equinox line, we are in summer.

Orientation: Uncertain, but approximately south-facing.
Saying: Senza sole nulla son Io [Without the sun I have nothing]
Notes: This sundial shows daylight savings time in Arabic numbers and non-daylight savings time in Roman numerals. This photo was taken: 5/26/13 at 8:31 am (local time). On this date, Italy would be on daylight savings time (“spring” ahead) so we read the Arabic numbers and we see we are between 8 and 9 am.

The three images of the simulated sundial are from the program Shadows Pro. To create these images, I created a vertical sundial at the coordinates above, facing west. The red line is summer solstice and the blue line is winter solstice declination line.

Hours Shown in the Sundials Here
French Hours(Ore Francesi) which was an early name for the equal hour system with two 12 hours days that began at midday and midnight.
Italian or Italic Hours (Ore Italiche) – the number of hours elapsed since the most recent sunset (hour 0) with 24 equal hours per day. Also referred to as an Hours Before Sunset Sundial.
Babylonian Hours – the number of elapsed since the most recent sunrise (hour 0) with 23 equal hours per day.
Unequal Hours or Biblical – 12 hours between sunrise an sunset, or during the night between sunset and the following sunrise. The duration of the hours can vary between 40 to 80 minutes during the year.
