The First Man in Rome by Colleen McCullough

Gaius Marius detected an odd shadow in him: there was the faintest tinge of exhaustion in the skin beneath his eyes, and his mouth was tight-lipped yet not of the right form to be tight-lipped.
    Gaius Julius Caesar Junior, twenty-two this year, was sturdier than his brother and even taller, a golden-blond fellow with bright blue eyes. Highly intelligent, thought Marius, yet not a forceful or opinionated young man.
    Together they were as handsome, Roman-featured, finely set-up a pair of sons as any Roman senator father might hope to sire. Senators of tomorrow.
    "You're fortunate in your sons, Gaius Julius," Marius said as the young men disposed themselves on the couch standing at right angles to their father's right; unless more guests were expected (or this was one of those scandalously progressive houses where the women lay down to dine), the third couch, at right angles to Marius's left, would remain vacant.
    "Yes, I think I'm fortunate," said Caesar, smiling at his sons with as much respect as love in his eyes. Then he turned on his elbow to look at Gaius Marius, his expression changing to a courteous curiosity. "You don't have any sons, do you?"
    "No," said Marius unregretfully.
    "But you are married?"
    "I believe so!" said Marius, and laughed. "We're all alike, we military men. Our real wife is the army."
    "That happens," said Caesar, and changed the subject.
    The predinner talk was cultivated, good-tempered, and very considerate, Marius noticed; no one in this house needed to put down anyone else who lived here, everyone stood upon excellent terms with everyone else, no latent discord rumbled an undertone. He became curious to see what the women were like, for the father after all was only one half of the source of this felicitous result; espoused to a Puteolan pudding though he was, Marius was no fool, and he personally knew of no wife of the Roman nobility who didn't have a large input to make when it came to the rearing of her children. No matter whether she was profligate or prude, idiot or intellectual, she was always a person to be reckoned with.
    Then they came in, the women. Marcia and the two Julias. Ravishing! Absolutely ravishing, including the mother. The servants set upright chairs for them inside the hollow center of the U formed by the three dining couches and their narrow tables, so that Marcia sat opposite her husband, Julia sat facing Gaius Marius, and Julilla sat facing her two brothers. When she knew her parents weren't looking at her but the guest was, Julilla stuck out her tongue at her brothers, Marius noted with amusement.
    Despite the absence of licker-fish and oysters and the presence of heavily watered wine, it was a delightful dinner served by unobtrusive, contented-looking slaves who never shoved rudely between the women and the tables, nor neglected a duty. The food was plain but excellently cooked, the natural flavors of meats, fruits, and vegetables undisguised by fishy garum essences and bizarre mixtures of exotic spices from the East; it was, in fact, the kind of food the soldier Marius liked best.
    Roast birds stuffed with simple blends of bread and onions and green herbs from the garden, the lightest of fresh-baked rolls, two kinds of olives, dumplings made of delicate spelt flour cooked with eggs and cheese, deliciously country-tasting sausages grilled over a brazier and basted with a thin coat of garlic and diluted honey, two excellent salads of lettuces, cucumbers, shallots, and celery (each with a differently flavored oil-and-vinegar dressing), and a wonderful lightly steamed medley of broccoli, baby squash, and cauliflower dashed over with oil and grated chestnut. The olive oil was sweet and of the first pressing, the salt dry, and the pepper—of the best quality—was kept whole until one of the diners signaled the lad who was its custodian to grind up a pinch in his mortar with his pestle, please. The meal finished with little fruit tarts, some sticky squares of sesame seed
