Symbols and Iconography: Comprehensive Study Notes

Symbols and Signs: Definitions and Context

• Symbols are marks or characters used as conventional representations of objects, functions, or processes.
• Symbols are generally easy to understand, readily legible, and simple in design characteristics.
• Symbols are often used to connect ideas and meanings.
• Meaning of symbols is highly contextual: they take their meaning from the context in which they are produced and consumed; they are culturally specific, even as some become universal.
• Symbols are shaped by sources and resources, formed by cultural structures, communicated through diverse channels, and understood in terms of the societies that create them.
• If an alien saw a heart, they might not understand it; context dictates how we read signs.
• Signs and symbols can be literal, analogical, or metaphorical, and can mean more than themselves.
• Example: heart shape is not anatomically accurate but references the anatomical heart and the concept of love.
• Logos function as signs for the companies or groups they represent, but are generally distinct from symbols.
• Logos vs symbols: logos are broader brand identity marks (can include woodmarks, text, symbol/images, or a combination) and are designed to represent a specific company or brand; logos are not typically treated as symbols in the same sense.
• A future plan: logos will be examined separately from symbols (in a few weeks).

Visualizing a Logo vs a Symbol: WiFi as an Example

• We'll look at a logo today, then the symbol associated with the concept (WiFi) to contrast logo vs symbol.
• Definition recap: a symbol is a visual element that stands for an idea or concept with broad cultural associations; a logo is a brand identity mark.

Medieval and Renaissance Roots of the Heart Symbol

• The heart symbol has a long history beyond modern graphic design.
• Earliest identified heart symbol (as a signifier for romantic love) appears in the allegory of Duergarde (Sweet gaze), a 13th-century Romaine de la Poi manuscript.
• The miniature shows a figure offering his heart to his lover, illustrating the giving and reception of romantic love; an upside-down heart can be seen in close inspection.
• In medieval times, the heart appears in various forms:
  • Vade Cuthiers, Poirier, and Chasson Belle Bonsage in Chantilly Codex (courtly songs for dances and courtship).
  • Caudier’s depiction of the belle bonsage forming a heart shape, indicating romance and courtship; additional hearts are included for clarity.
• The “book of love” (poems connected to Sala) features a readily identifiable heart symbol, red and upright, reinforcing romantic love.
• The heart is used to symbolize love and affection in a variety of medieval and Renaissance contexts.

Sacred Heart: Evolution and Symbolic Meanings

• In 1486, Guebet Huch produces imagery of the stigmata (the five wounds of Christ) with the heart symbol not anatomically depicted but pierced by a spear—an abstract association with the crucified Christ.
• Sacred Heart evolves to symbolize God’s love, divine truthfulness, and illumination; Venitas (truthfulness) is indicated by light illuminating Christ’s face around the sacred heart.
• Jose de Paas’s 1770 painting Adoration of the Sacred Heart with Saints Ignatius Loyola and Luis Gonzaga merges the sacred heart with saints and divine love.
• In many Spanish Catholic works, the sacred heart is surrounded by putti (small winged baby angels) and signals Christ’s love, divine truth, and sanctified healing.
• The late 18th century marks a period in which medical discourse and dissection influence depictions: the heart imagery begins to merge with anatomical ideas.

Ideographs and Symbolic Evolution Beyond the Heart

• Symbols expand to broader ideographs with multiple associations and cultural meanings.
• Other symbols, such as various-star shapes and other traditional icons, carry longstanding cultural associations dating back to the ancient world.
• Today’s class focuses on symbols designed by individuals, organizations, or associations to convey specific messages.

The Red Cross: History, Design, and Cultural Contours

• The Red Cross symbol emerged from the First Geneva Convention (1863) as a universal sign of neutrality for medical personnel and humanitarian aid in war.
• Design origin and neutrality intent:
  • Henri Dunant (a Swiss observer) and collaborators (Louis Appia and General Henri Dufour) contributed to the emblem’s development.
  • The emblem is the inverse of the Swiss flag (a white cross on a red field) to denote neutrality, high visibility from a distance, and ease of on-the-fly reproduction.
• Color and visibility: red is a color associated with danger and medical aid; the mark is high-contrast and easily reproducible with simple two-line design.
• Global adoption and variations:
  • Since 1863, the emblem has been recognized by about 194 countries.
  • Some nations prefer the red crescent or red lion in contexts where the red cross is culturally inappropriate.
  • In 2004, a crystal-like variant emerged, offering alternatives beyond the red cross, yet still carrying the protective intent.
• Usage and safeguards:
  • It designates protection for medical personnel and humanitarian workers; misuse is considered a war crime.
  • In military and cultural contexts, its use is tightly regulated; in popular media (video games, advertising) it is generally discouraged to maintain the symbol’s seriousness.
• Controversies and misunderstandings:
  • Some countries use other emblems for contextual fit; the Red Cross remains a strong symbol of protection and neutrality.
  • The symbol’s easy reproduction leads to concerns about misuse (infiltration by combatants, etc.).

Copyright Symbol: History, Meaning, and Legal Boundaries

• The copyright symbol (the circle enclosing a C) was reinforced through a revision of copyright law; it did not come into universal, one-time creation in 1790 but evolved over time.
• Legal specifics (as discussed in the lecture):
  • In the United States, copyright extends to
    $75\text{ years after the death of the maker}$
  • The 75-year term is connected to lobbying by industry (notably Disney) to extend protection for works such as Mickey Mouse beyond earlier terms.
  • The copyright symbol is widely embedded in metadata of digital works rather than visually on all works.
• The symbol’s purpose: to acknowledge authorship and to protect reproductions of a particular work from unauthorized copying.
• Distinction between copyright and trademark:
  • Copyright protects a specific work.
  • Trademark protects brand identity (logos, names, marks used commercially).
• The open question about usage in practice:
  • Some symbols and logos are not legally copyrighted or trademarked in certain contexts, but cultural and ethical norms still discourage misuse.

The Peace Symbol: Gerald Holton and Multivalent Readings

• The peace symbol (CND symbol) was developed in 1958 by Gerald Holton (some references spell the surname as Colton in informal retellings) during the Cold War era.
• Dual readings of the symbol:
  • Semaphore-based reading: the lines within the circle combine to form letters N and D (nuclear disarmament).
  • Alternative reading: the central element as a broken cross (death of man) with the circle representing potential unborn life, i.e., the unborn child and the threat to future generations.
• Historical context and influence:
  • It drew on Rudolph Koch’s Book of Signs (1930) for symbolic lineage and typographic symbolism.
  • The symbol’s intent was universal: easy to reproduce, easily understood, and capable of proliferating across contexts.
• Usage history and cultural impact:
  • From posters for nuclear disarmament to hippie movement iconography, and Vietnam War protests.
  • It became a broad peace symbol used by anti-war and pro-peace groups worldwide.
• Open licensing:
  • Holton did not seek copyright or trademark protection; the symbol was intended to proliferate freely.

The Recycle Symbol: Gary Anderson, the CCA, and the Mobius Idea

• The recycle symbol originated in 1970 from a nationwide design competition sponsored by the Container Corporation of America (CCA) to mark recyclability of materials (especially paper products).
• Designer and concept:
  • Gary Anderson submitted a design that inverted into the familiar three-arrow loop.
  • The CCA added a layered meaning by inverting the symbol and placing a tree at the center to underscore the paper recycling relationship—from raw material to recycled product.
• Trademark considerations:
  • The CCA attempted to trademark the symbol as a corporate mark, but environmental groups and other stakeholders argued against granting exclusive rights to a symbol with broad environmental significance.
  • As a result, the recycling symbol itself remains open and variably used across contexts and regions.
• Symbolic variability and scope:
  • Different materials (aluminum, steel, glass, plastic, paper) may use variations of the three-arrow motif to denote recycling.
  • The symbol serves to indicate the recycling process (reclaimed material becoming a new product) but is not a single, universal, legally defined icon.
• Historical lineage of the symbol:
  • The recycling motif traces to earlier trade symbols such as the amphora symbol (sixth century) used for standard trade measurements, which later evolved into shorthand in the sixteenth century and then into modern digital contexts.

The At Symbol: From Ancient Trade to Email Addresses

• The word and symbol @ have a long, layered history:
  • In the sixth century, the at-like symbol appeared in trade contexts as a sign associated with amphorae (a vessel used to trade goods like grain and oil).
  • In the sixteenth century, it appeared as shorthand in Latin for ad (meaning ‘at’), especially in church archives and treasuries.
  • In the nineteenth century, it appeared on typewriter keyboards as a practical symbol to indicate the “at” context in various texts.
  • In modern digital communication, the at symbol separates user names from domain hosts (e.g., user@example.com) and enabled scalable addressing on networks.

Power Symbol: State of On/Off and UI Adoption

• The power symbol (a circle with a vertical line) represents the universal on/off state on many devices.
• Rationale:
  • It combines the concepts of “on” and “off” into a single, easily recognizable glyph.
  • It is highly legible from a distance and across cultures.
• Cultural persistence and changes:
  • While once ubiquitous on devices, newer interfaces (touchscreens, biometric sensors) reduce reliance on a physical power button, yet the symbol persists on many TVs, remotes, and appliances.

Wireless Fidelity (WiFi) Symbol: Origin and Adoption

• The term WiFi is widely used; in Europe the standard is often referred to as EV.
• Development and standardization:
  • The concept and symbol were developed in the context of IEEE standards.
  • John O’Sullivan is credited with key work in wireless connectivity (the broader development of WiFi protocols was collaborative).
• Cultural context:
  • In late 1990s and early 2000s, airports, hostels, and public spaces displayed the WiFi symbol to indicate wireless internet access.

The Accessible Icon: Disability Representation and Design Rationale

• Evolution from older to newer accessibility icons:
  • Earlier icons used disproportionate human body ratios; newer designs standardize limb proportions to align with common human figures.
  • The seated wheelchair figure icon evolved to emphasize active mobility (head forward, arm back, leg forward) to convey agency and movement.
• Functional design choices:
  • The icon’s cutouts were designed for stencil-based street art: a single stencil can produce the full symbol when spray-painted.
• Open-source and municipal adoption:
  • The updated icon has been released as open-source, enabling broad adoption without copyright restrictions.
  • It is used in major cities (e.g., New York, Los Angeles, Toronto) but is not universally adopted by every city or institution.
• Limitations and representation gaps:
  • The symbol primarily represents mobility-impaired individuals who use wheelchairs and does not fully represent other disabilities (vision, hearing, cognitive, mental health).
• Practical/ethical note:
  • While open to widespread use, there is ongoing discussion about ensuring inclusive representation in universal accessibility symbols.

Computer Icons and Early Digital Pictograms (Game Boy/Icons)

• The earliest Game Boy and related digital icons used pixelated, disjointed forms typical of early handheld devices.
• Icon design aims:
  • Create universally understandable icons that transcend language barriers.
  • Allow simple, scalable symbols to convey functions like cut, delete, etc.
• Susan Kare and related design lineage (contextual recall):
  • Early Mac icons (e.g., scissors for cut, trash bin for delete) established a foundation for later pixel/icon design in computing hardware and software.
• Relationship to 1980s–1990s digital symbolism:
  • The era emphasized minimal, legible icons meant to be recognized quickly across platforms.

Emojis: History, Development, and Cross-Platform Variation

• Shigetaka Kurita and the origin of emojis (1998–1999):
  • Created for a Japanese mobile carrier (NTT DoCoMo) to enhance electronic messaging and convey emotion.
  • The term emoji is derived from English: emotion icons; emoticon is an earlier term (emotion pictographs via text).
• Evolution and typology:
  • The original emoji set included universal symbols (heart, star, hand gestures, accessibility icons, etc.) and was expanded over time.
  • Emojis are culturally influenced and often rely on fonts (Zapf Dingbats and other typefaces) and platform-specific rendering.
• Cross-platform variation and brand influence:
  • Different platforms (iOS, Android, Windows, etc.) render the same Unicode emoji differently, leading to variation in appearance.
  • The emoji glyphs are not immutable; platform designers influence their appearance (e.g., iPhone vs. Google Pixel emoji) while maintaining underlying semantics.
• Brand and user experience implications:
  • Brands may stylize their emoji sets to reinforce identity and brand equity.
  • Users may experience consistency challenges when switching devices, prompting preference for standardized glyphs or customizable emoji palettes.
• Current landscape (as discussed in the lecture):
  • A broad ecosystem of emojis with continued evolution, user-generated creativity, and AI-assisted customization in some contexts.

Key Takeaways: Connections, Implications, and Ethical Notes

• Distinction recap: symbols vs signs vs logos. Symbols carry meaning within cultural and contextual frames; signs can be literal or metaphorical; logos function as brand identity marks but are not necessarily symbols in the broader semiotic sense.
• History matters: many modern symbols (Red Cross, peace symbol, recycling, copyright, power, WiFi, accessibility icons, emojis) have long histories and layered meanings that interact with culture, law, and technology.
• Open vs restricted use:
  • Some symbols are open (e.g., peace symbol, recycling symbol) to encourage broad adoption, while others carry legal protections (copyright, trademarks) or ethical considerations for usage (medical neutrality, humanitarian contexts).
• Cultural sensitivity and accuracy:
  • Symbols can traverse cultural boundaries but must be mindful of cultural appropriateness (e.g., Red Cross vs Red Crescent; disability icons across diverse experiences).
• Design rationale:
  • Simplicity, contrast, and ease of reproduction are recurring design goals for symbols intended to travel across media and contexts.
• Real-world relevance:
  • Understanding these symbols helps in analyzing posters, advertisements, books, and digital interfaces, as well as in recognizing ethical and legal dimensions of iconography in media production.
• Connections to foundational principles:
  • Semiotics: signs and symbols operate within systems of meaning shaped by culture and history.
  • Visual communication: legibility, universality, and interpretive flexibility influence symbol design and use.
• Practical implications for exam preparation:
  • Be able to distinguish between symbols, signs, and logos and explain how context shapes meaning.
  • Recall key historical origins and designers associated with major symbols (e.g., Red Cross, Peace symbol, Recycling symbol, Copyright symbol, Emoji history).
  • Understand legal and ethical considerations around symbol use (copyright vs trademark, neutrality in humanitarian contexts, open-source vs restricted symbols).
  • Recognize how symbols evolve (e.g., sacred heart imagery evolving with medical discourse) and how new icons (disabled-access icon, WiFi) gain cultural purchase.
• Examples and hypotheticals to remember:
  • Alien reader example for heart symbol: context changes meaning.
  • Street-art stencil vs printed poster: design choices (cut-out shapes, reproducibility).
  • Open-source accessibility icon used across major cities vs non-adoption by some institutions.
  • Cross-platform emoji rendering differences affecting communication and brand alignment.
