Final answer:
The lower left ordinary of a coat of arms is usually adorned with motifs and symbols such as the fleur-de-lis in French heraldry, reflecting familial or political ties.
Step-by-step explanation:
The lower left ordinary of the coat of arms generally refers to the bottom left section when facing the shield. From the provided references, we have a mixture of information regarding the iconography related to the French monarchy and other historical contexts. Nonetheless, in traditional heraldic terms, ordinaries are simple geometric shapes on a shield. The lower part might contain symbols representing various familial or political allegiances or achievements. While the specific coat of arms isn't detailed in the provided references, the lower left area might often display a motif like a fleur-de-lis, which is a common symbol in French heraldry, indicating a connection to the French royal family. This symbol was not only a sign of royalty but was also used by other rulers such as the Mamluk Sultan, suggesting a wider adoption beyond just the French crown. Since a coat of arms includes different elements to denote the lineage, the lower left ordinary could also contain symbols representing the individual or family's role, property, or official capacity, as observed with other symbols like the eagles and arrows in the Great Seal of the United States represented in the Lansdowne Portrait. The use of such symbols would be significant in understanding the historical context in which they were granted and used.
